Welcome to the 4 Series B MSO. The 4 Series MSO Oscilloscopes (MSO44B, MSO46B) are 4- and 6-channel oscilloscopes with the world's first FlexChannel^® inputs, enabling you to efficiently and cost-effectively perform mixed signal debugging on virtually any design.

Electrostatic discharge (ESD) can damage oscilloscope and some probe inputs. This topic discusses how to avoid this type of damage.

Electrostatic discharge (ESD) is a concern when handling any electronic equipment. The instrument is designed with robust ESD protection, however it is still possible that large discharges of static electricity directly into the signal input may damage the instrument. Use the following techniques to prevent electrostatic discharge from damaging the instrument.

• Discharge the static voltage from your body by wearing a grounded antistatic wrist strap while connecting and disconnecting cables, probes, and adapters. The instrument provides a ground connection to which to attach a wrist strap (on the Probe Comp ground connector).
• A cable that is left unconnected on a bench can develop a large static charge. Discharge the static voltage from all cables before connecting them to the instrument or device under test by momentarily grounding the center conductor of the cable, or by connecting a 50 Ω termination to one end, before attaching the cable to the instrument.
• Before you apply power, connect the instrument to an electrically-neutral reference point, such as earth ground. To do this, plug the three-pronged power cord into an outlet grounded to earth ground. Grounding the oscilloscope is necessary to ensure safety and to take accurate measurements.
• If you are working with static sensitive components, ground yourself. Static electricity that builds up on your body can damage static-sensitive components. Wear a wrist strap to safely send static charges on your body to earth ground.
• The oscilloscope must share the same ground as any circuits that you plan to test.

Make sure that you received everything you ordered. If anything is missing, visit tek.com/contact-tek to find contacts in your area.

Check the packing list that came with your instrument to verify that you have received all standard accessories and ordered items. If you purchased factory installed options, tap Help > About to confirm that the option(s) are listed in the Installed Options table.

Use the correct process to eliminate the chance of pinching your thumb or rear-panel-connected cables while rotating the handle.

WARNING:Hold the top of the handle to rotate the handle on the instrument. Do not hold the handle from the sides and rotate, as this can pinch the base of your thumb between the handle and the case.

CAUTION:If you have routed any cables between the handle and the case, be careful when rotating the handle so that you do not pinch the cables.

Lock an instrument to a test bench or equipment rack to prevent property loss.

To secure the instrument to a workbench, rack, or other location, attach a standard laptop security lock to the rear panel of the instrument.

Probes connect the instrument to your device under test (DUT). Use a probe that best matches your signal measurement needs.

Connecting Probes

Connect TPP Series, TekVPI+, TekVPI, or other supported Tektronix analog probes by pushing them into a FlexChannel connector. The probe base latch locks with a 'click' when the probe is fully seated.

TekVPI probes automatically set the channel input parameters for that probe (bandwidth, attenuation, termination, and so on). If a probe has a Menu button, push that button to open an on-screen configuration menu. Follow instructions provided with active probes to set their parameters (auto zero, degauss, and so on).

To connect a TLP058 FlexChannel Logic Probe or a TDP7700 Series TriMode™ Probe:

1. Move the locking lever to the unlocked position, then let go to reset locking lever to the center position.
2. Insert the probe into a FlexChannel connector until fully seated and the lock mechanism clicks.
3. Move the locking lever to the locked position. The status light should be a solid green.
4. To disconnect the TLP058 probe, move and hold the locking lever at the unlocked position and pull out the probe. Do not pull on the ribbon cable while removing the probe.

Connect a BNC probe or cable by pushing it onto a channel BNC bayonet connector and turn the lock mechanism clockwise until it locks.

Note:Connecting a probe does not automatically enable that channel (make it active). Use the instrument controls or programmatic interface to turn on a channel and open its configuration menu to verify or change probe or cable settings (bandwidth, attenuation, termination and so on).

The front panel controls provide direct access to key instrument settings such as vertical, horizontal, trigger, cursors, and zoom. The connectors are where you input signals with probes or cables, or insert USB devices.

Note:Refer to the instrument help for detailed information on using the controls to display waveforms and take measurements.

1. Acquisition and Cursors controls:
   • Run/Stop starts and stops waveform acquisition. The button color indicates the acquisition status (green = running and acquiring; red = stopped). When stopped, the oscilloscope shows waveforms from the last completed acquisition. The Run/Stop button on the screen also shows the acquisition status.
   • Cursors button turns screen cursors on or off. Use the Multipurpose knobs to move the cursors. Double-tap the cursor readouts, or on a cursor bar (line), to open the configuration menu to set cursor types and functionality.
   • Fast Acq™ enables or disables the fast acquisition mode. FastAcq provides high-speed waveform capture that reduces the dead time between waveform acquisitions, enabling the capture and display of transient events such as glitches and runt pulses. It is helpful in finding elusive signal anomalies. Fast acquisition mode can also display waveform phenomena at an intensity that reflects their rate of occurrence.
   • Single/Seq enables making a single waveform acquisition, or a specified number of acquisitions (as set in the Acquisition configuration menu). Pushing Single/Seq turns off Run/Stop mode and takes a single acquisition. The button color indicates the acquisition status (quick green flash = single acquisition acquired; solid green = waiting for trigger event). Pushing Single/Seq again takes another single acquisition.
   • High Res applies unique finite impulse response (FIR) filters based on the current sample rate. This FIR filter maintains the maximum bandwidth possible for that sample rate while rejecting aliasing. The filter removes noise from the oscilloscope amplifiers and ADC above the usable bandwidth for the selected sample rate. Implementation of the filter in hardware, ahead of the trigger and storage, reduces trigger jitter and enables using Fast Acq mode while in High Res mode.

     High Res mode also guarantees at least 12 bits of vertical resolution. The number of bits of resolution is displayed in the Acquisition badge at the bottom of the screen. The Horizontal badge also updates to show the sample rate and record length settings while in High Res mode.

   • Clear deletes the current acquisitions and measurement values from memory.
2. Multipurpose knobs: The Multipurpose knobs A and B move cursors and set parameter values in configuration menu input fields. Selecting an menu field that can use a Multipurpose knob assigns the indicated knob to change the value in that input field. The ring around each knob lights when you can use that knob to do an action. Push a Multipurpose knob to enable the Fine mode for making smaller increment changes. Push the knob again to exit Fine mode.
3. Trigger controls:
   • Force forces a trigger event at a random point in the waveform and captures the acquisition.
   • Level sets the amplitude level that the signal must pass through to be considered a valid transition. The color of the Level knob LED indicates the trigger source except for dual-level triggers.

     The Level knob is disabled when the trigger type requires two level settings or other trigger qualifiers (set from the Trigger configuration menu). Push the knob to set the threshold level to 50% of the peak-to-peak amplitude range of the signal.

   • Slope sets the signal transition direction to detect for a trigger (low to high, high to low, or either direction). Push the button to cycle through the selections. The Slope button is disabled when the trigger type requires other slope qualifiers (set from the Trigger configuration menu).
   • Mode sets how the instrument behaves in the absence or presence of a trigger event:
     • Auto trigger mode enables the instrument to acquire and display a waveform whether or not a trigger event occurs. If a trigger event occurs, the instrument displays a stable waveform. If a trigger event does not occur, the instrument forces a trigger event and acquisition and displays an unstable waveform.
     • Normal trigger mode sets the instrument to acquire and display a waveform only when there is a valid trigger event. If no trigger occurs, the last waveform record acquired remains on the display. If no last waveform exists, no waveform is displayed.
4. Vertical controls:
   
   
   • Position moves the selected waveform (Channel, Math, Reference, Bus) and its graticule up or down on the screen. The color of the Position knob indicates which waveform the knob is controlling. Push the knob to set the threshold level to 50% of the peak-to-peak amplitude range of the signal.
   • Scale sets the amplitude units per vertical graticule division of the selected waveform. The scale values are shown on the right edge of the horizontal graticule lines, and are specific to the selected waveform in both Stacked or Overlay modes (in other words, each waveform has its own unique vertical graticule settings regardless of display mode). The color of the Scale knob indicates which waveform the knob is controlling.
   • Channel buttons turn on (display), select, or turn off Channel, Math, Reference, or Bus waveforms. The number of channel buttons depends on the instrument model. The buttons operate as follows:
     • If the channel is not displayed, pushing a Channel button turns on that channel to the Waveform view.
     • If the channel is on the screen and is not selected, pushing that channel's button selects that channel.
     • If the channel is on the screen and is also selected, pushing that channel's button turns that channel off (removes it from Waveform view).
   • Math button adds or selects a Math waveform on the Waveform view.
     • If no Math waveform exists, pushing the Math button adds a Math waveform to the Waveform view and opens the Math configuration menu.
     • If only one Math waveform is displayed, pushing the button turns off the Math waveform (removes it from Waveform view). Push the button again to display the waveform.
     • If two or more Math waveforms are displayed, pushing the button cycles through selecting each math waveform.
   • Ref button adds or selects a Reference (saved) waveform on the Waveform view.
     • If no Reference waveform exists, pushing the Ref button opens the Browse Waveform Files configuration menu. Navigate to and select a waveform file (*.wfm) and tap Recall to load and display the reference waveform.
     • If only one Reference waveform is displayed, pushing the button turns off the Reference waveform (removes it from the Waveform View). Push the button again to display the waveform.
     • If two or more Reference waveforms are displayed, pushing the button cycles through selecting each Reference waveform.
   • Bus button adds or selects a bus waveform on the Waveform view.
     • If no Bus waveform exists, pushing the Bus button adds a Bus waveform to the Waveform view and opens the Bus configuration menu.
     • If only one Bus waveform is displayed, pushing the button turns off the Bus waveform (removes it from Waveform view).
     • If two or more Bus waveforms are displayed, pushing the button cycles through selecting each Bus waveform.
5. Horizontal controls:
   • Position moves the waveform and graticule side to side on the screen (changing the trigger point position in the waveform record). Push the knob to center the trigger event to the center graticule on the Waveform view.
   • Scale sets the time per major horizontal graticule division and samples/second parameters for the oscilloscope. Scale applies to all waveforms. Push the knob to enable the Fine mode for making smaller increment changes. Push the knob again to exit Fine mode.
   • Zoom opens the Zoom mode. Push Zoom again to close zoom mode.
   • Zoom knob (center knob) increases or decreases the area of the zoom box in the Zoom Waveform Overview, which in turn controls the zoom amount of the waveforms shown in the main Zoom view.
   • Pan knob (outer knob) moves the Zoom box left or right in the Zoom Waveform Overview, which in turn controls the part of the waveform shown in the main Zoom view.
   • Navigate (left and right arrow) buttons puts the oscilloscope in Zoom mode and positions the previous or next search point in the waveform record to the center graticule of the Waveform view. There must be a Search badge present in the Results bar before the Navigate function will operate. Press and hold a front panel navigate button to continue moving to the next search point in that direction.

     The front panel Navigate buttons can also be used for the Previous and Next button functions on measurement badges.

6. Miscellaneous controls:
   • Touch Off turns touch screen capability off. The Touch Off button is lighted when the touch screen is turned off.
   • Save is a one-push save operation that uses the current File > Save As settings to save screen shots (including open menus and dialog boxes), waveform files, instrument settings, and so on.
     • If a File > Save or File > Save As operation has occurred since the last instrument startup, pushing Save saves the file types to the location last set in the Save As configuration menu.
     • If no file save operation has occurred since the last instrument startup, pushing Save opens the Save As configuration menu. Select a tab to select the type of file to save (Screen Capture, Waveform, and so on), set any associated parameters, and where to save it, and select OK. The specified file or files are saved. The next time you push Save, the same type files are saved.
     • Screen Captures capture the entire screen, including most displayed configuration menus and dialog boxes.
   • Default Setup restores the oscilloscope settings (horizontal, vertical, scale, position, and so on) to the factory default settings.
   • Autoset automatically displays a stable waveform.
7. Ground and Probe Compensation connectors: The Ground and Probe Compensation connectors are located at the lower right side of the instrument, near the front panel. The Ground connector (the small hole in the case) provides an electrically grounded (through a resistor) connection point to attach an anti-static wrist strap, to reduce electrostatic damage (ESD) while you handle or probe the DUT.

   The Probe Compensation connections provide a ground connector (upper tab) and 1 kHz square wave source (lower tab) for adjusting the high-frequency response of a passive probe (probe compensation). The oscilloscope uses this signal to automatically compensate supported probes, including the ones that ship with the product.

8. USB Host ports (USB 3.0 and 2.0): USB ports are located at the lower right corner of the front panel, and on the rear panel. Connect USB flash drives to which you can save or recall data (such as instrument software updates, waveforms, settings, and screen captures), or connect peripheral devices such as a mouse or keyboard.
9. FlexChannel probe connectors: FlexChannel connectors support all TekVPI+ and TekVPI measurement probes, BNC passive probes, the TPL058 FlexChannel Logic Probe, and BNC cables. You connect most probes simply by pushing them into the connector until the probe seats with a click.

   
   

   

   
   

10. Aux In auxiliary trigger input connector. A connector to which you can connect an external trigger input signal. Use the Aux In trigger signal with the Edge trigger mode.

5. Configuration Menus let you quickly change the parameters of the selected user interface item. You can open configuration menus by double-tapping on badges, screen objects, or screen areas. See Configuration menus.

Each area of the user interface has a specific function that helps manage information or controls. This topic shows and describes the key user interface elements.

1. The Waveform Record View is a graphical high-level view of the overall waveform record length, how much of the record is on the screen (shown in brackets), the location of key time events including the trigger event, and the current position of waveforms cursors.
   
   
   

   If you are displaying a Reference waveform that is shorter than the current acquisition record length, or you are changing the horizontal time scale while the oscilloscope acquisition is stopped, the brackets change position to show the part of the waveform record that is being viewed relative to the current acquisition total record length.

   
   
   

   If cursors are active on a waveform, the Waveform Record View shows the relative cursor positions as small vertical dashed lines.

   
   
   

   When in Zoom mode, the Waveform Record View is replaced with the Zoom Overview. See Zoom user interface.

2. The Expansion Point icon on the waveform view shows the center point around which the waveform expands and compresses when changing horizontal settings.
   
   
3. The Trigger Position Indicator shows where the trigger event occurred in the waveform record. The trigger icon is displayed in the waveform slice that is the trigger source.
   
   
4. The Zoom icon (in upper right corner of Waveform and Plot views) toggles zoom on and off. The front panel Zoom button and knobs also turn on zoom mode and change the position and horizontal size of the Zoom Box.
   
   
5. The Trigger Level Indicator icon(s) shows the trigger level on the trigger source waveform. Some trigger types require two trigger levels.
6. Measurement and Search badges show measurement and search results. See Badges. See Add a measurement.
7. The Results Bar Handle opens or closes the Results bar, to maximize waveform screen viewing when needed. To reopen the Results bar, either tap the handle icon or swipe left from the right side of the display.
8. The System badges show global instrument settings (Horizontal, Trigger, Acquisition, Run/Stop status, and Date/Time). See Badges.
9. The Inactive Channel buttons add channel waveforms to the Waveform view and add an associated Channel badge to the Settings bar.

   The Add New Math, Add New Ref, and Add New Bus buttons add the corresponding signal to the Waveform view, and add an associated Waveform badge to the Settings bar. You can add any number of Math, Reference, and Bus waveforms, limited only by system memory.

   The optional AFG button opens the AFG configuration menu to set and enable the AFG output. This button is only present if the AFG option is installed.

   The optional DVM button lets you use an analog probe to take DC, AC RMS, or DC+AC RMS voltage measurements on your DUT. Tap the button to add a DVM badge to the Results Bar and open a configuration menu. The DVM option also enables a trigger frequency counter, accessible from the Mode & Holdoff panel in the Trigger badge menu. This button is only present if the DVM option is installed.

10. Double-tap a badge to open its associated configuration menu. See Badges. See Configuration menus.

    If you add more Channel or Waveform badges than can fit in the waveform badge display area, tap the scroll buttons at each end of the waveform badge area to scroll and display hidden badges.

11. The Waveform Handles on each waveform identify the source of that waveform (Cx for channels, Mx for Math waveforms, Rx for Reference waveforms, Bx for bus waveforms). The waveform handles are at the zero-volt level of the waveform by default. The currently selected waveform handle is a solid color; unselected waveform handles are outlined.

    Double-tapping a waveform handle opens the configuration menu for that waveform.

    For digital channels, the waveform handle shows the channel number, each individual digital signal labeled D0–D7 and displayed with a different color.

    
    
    

    Double-tapping a digital waveform handle opens the digital channel configuration menu.

    Dragging a digital signal handle over another handle swaps those two signals on the waveform.

12. The probe Dynamic Range Limit Markers are displayed just within the left-hand graticule edge, based at the channel vertical trace handle position and extending up and down to the dynamic range limits of the probe. The markers are only displayed if compatible probes are used. Signals must be within the probe dynamic range for the oscilloscope to correctly display and measure the signals.

    The markers are displayed, for about three seconds, after any Offset, Position, or Scale control change that leaves the channel dynamic range limits within the acquisition window. After about three seconds the markers become short lines at the left edge of the graticule. If the dynamic range is too small to display the arrows, the arrows are omitted. Examples of all three marker versions are shown.

    

Badges are rectangular icons that show waveform, measurement, and instrument settings or readouts. Badges also provide fast access to configuration menus. The badge types are Channel, Waveform, Measurement, Search, and System.

Channel and Waveform badges

Channel and Waveform (Math, Ref, Bus, Trend) badges are shown in the settings bar, located along the bottom left of the screen. Each waveform has its own badge. The badges show high-level settings for each displayed channel or waveform. Double-tap a badge to open its configuration menu.

Most Channel and Waveform badges also have Scale buttons, shown by single-tapping the badge. Use the Scale buttons to increase or decrease the vertical scale setting for that waveform.

You can drag Channel and Waveform badges to change their position in the Settings bar and open the badge right-click menu to access a quick-action menu.

There are two ways to delete Channel and Waveform badges.

• Right-click the badge and turn it off.
• Flick the badge off the bottom edge of the display to remove it from the Settings bar. Flicking upwards from the bottom edge of the Settings bar recovers the badge. Badge recovery is only possible within 10 seconds of removal.

Channel badges are listed in the channel order unless you have moved them. Channel badges may also display short error or warning messages. For more information double-tap the badge to open its configuration menu, or search the instrument Help.

Waveform badges (Math, Ref, Bus, Trend) are listed in the order created (unless they have been moved), and are grouped together by type. Deleting a Waveform badge does not change the order or names of the remaining badges.

Measurement badges

Measurement badges are located in the Results bar. They show measurements or search results. The badge title also shows the measurement source or sources. To add a Measurement badge, tap the Add New Measurement button and select a measurement.

Double-tap a Measurement badge to open its configuration menu to change or refine settings. The default measurement badge readout shows the measurement's mean (μ) value.

Some measurements and their badges are only available as options. For example, Power measurements are only listed in the Add New Measurement menu if the required power option is installed.

Wide Badge: Wide badge displays all the phases results in a separate column. All sub-measurements are listed in the results badge in the first column. The common result such as Frequency is applicable to all the (3) phases and displayed as single value. The configured sources for each phase are displayed in channel colors. The Wide Badge applies to IMDA measurements only.

To add statistical readouts to individual measurement badges, double-tap a measurement badge to open its configuration menu and select Show Statistics in Badge. The measurement badge displays the standard deviation (σ) value. The standard deviation is zero, when the population is one.

Some Measurement badges also have Navigation buttons, shown by single-tapping the badge.

The < (Previous) and > (Next) buttons center the waveform in the display at the position of the previous or next measurement point in the record (for measurements that take more than one measurement per acquisition).

The Min' and Max' navigation buttons center the waveform in the display at the minimum or maximum value for that measurement in the current acquisition.

The prime symbol (') shown on measurement readings and Min/Max buttons indicates that the value shown (or moved to in the case of Min/Max buttons and waveforms) is from the current acquisition. Lack of a prime symbol means the value is from all acquisitions.

The Measurement badge displays Status and Failures information when pass/fail testing is enabled through the configuration menu. The Status line shows Pass (green) or Fail (red) according to the conditions defined in the Pass/Fail Testing panel. The number of Failures are displayed when statistics are shown in the badge. The Pass/Fail status, number of Failures, and the Limit(s) set in the Pass/Fail Testing panel are available in the Measurement Results table.

Signal Clipping and Badges

WARNING:Clipping is caused by excessive or dangerous voltage at the probe tip, and/or a vertical scale setting that is not adequate to display the entire vertical range of the waveform. Excessive voltage at the probe tip can injure the operator and cause damage to the probe and/or instrument.

This instrument shows a warning triangle symbol and the words Clipping in a Channel badge when a vertical clipping condition exists. Any measurement badges associated with that channel also indicate a clipping condition by turning the measurement text red and listing the type of clipping (positive or negative).

To close the clipping message, change the vertical scale to show the entire waveform, disconnect the probe tip from the excessive voltage source, and check that you are probing the correct signal using the correct probe.

Clipping causes inaccurate amplitude-related measurement results. Clipping also causes inaccurate amplitude values in saved waveform files. If a math waveform is clipped, it will not affect amplitude measurements on that math waveform.

Error Messages and Badges

This instrument shows a warning triangle symbol and an error message abbreviation in a Channel badge when an error occurs.

To remove the message from the badge, clear the error as indicated in the table.
