Operating information
The TPP0850 Probe is a high impedance probe with 50X attenuation that is designed for use with Tektronix 4/5/6 Series Mixed Signal Oscilloscopes.
Connect the probe as shown in the illustrations below. Compensate the probe before initial use.
Compensate the TPP Series probes
Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. The oscilloscope can automatically test and store compensation values for an unlimited number of probe/channel combinations.
About this task
The oscilloscope stores the compensation values for each probe/channel combination, and automatically recalls the compensation values when you plug in the probe. Probe compensation status is shown in the Probe Setup panel of the Channel configuration menu.
- If the Probe Compensation Status field displays Pass, the probe is compensated and ready for use.
- If the Probe Compensation Status field displays Default, the attached probe has not been compensated and needs to have this probe compensation procedure run.
- If the Probe Compensation Status field displays Fail, the attached probe has failed the probe compensation procedure. Reconnect the probe and run probe compensation again.
- If there is no probe compensation status field shown in the panel, the oscilloscope cannot store compensation values for that probe. See the oscilloscope Help for how to manually compensate passive probes not supported by the probe compensation function.
Before you begin
The oscilloscope must be powered on for at least 20 minutes before compensating a probe.
Procedure
 | Note:Doing a Default Setup does not delete probe compensation values. A factory calibration does delete all stored probe compensation values. |
- Connect the probe tip and ground lead of the probe to the PROBE COMP terminals.
Note:Connect only one probe at a time to the PROBE COMP terminals. - Repeat these steps to compensate supported probes on other channels of the oscilloscope.Note:For most accurate measurements, open the Probe Setup panel and verify the Probe Compensation Status is Pass whenever you attach a probe to a channel.
Standard accessories
| WARNING:Do not substitute accessories from other products for use with this probe. Only use the accessories that are included with this probe. |
| WARNING:To avoid electric shock when using the probe or accessories, keep your fingers behind the finger guard of the probe body and away from the shaded area shown in the accessory illustrations below. |

Pollution degree description
A measure of the contaminants that could occur in the environment around and within a product. Typically the internal environment inside a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.
- Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs. Products in this category are generally encapsulated, hermetically sealed, or located in clean rooms.
- Pollution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is caused by condensation must be expected. This location is a typical office/home environment. Temporary condensation occurs only when the product is out of service.
- Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.
- Pollution Degree 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor locations.
Pollution degree rating
Pollution Degree 2
Measurement and overvoltage category descriptions
Measurement terminals on this product may be rated for measuring mains voltages from one or more of the following categories (see specific ratings marked on the product and in the manual).
- Overvoltage Category I. For equipment intended to be connected to a mains supply in which means have been taken to substantially and reliably reduce transient overvoltages to a level where they cannot cause a hazard.
- Measurement Category II. For measurements performed on circuits directly connected to the low-voltage installation.
- Measurement Category III. For measurements performed in the building installation.
- Measurement Category IV. For measurements performed at the source of low-voltage installation.
| Note:Only mains power supply circuits have an overvoltage category rating. Only
measurement circuits have a measurement category rating. Other circuits within the
product do not have either rating. |

Probes and test leads
Before connecting probes or test leads, connect the power cord from the power connector to a properly grounded power outlet.
Keep fingers behind the protective barrier, protective finger guard, or tactile indicator on the probes. Remove all probes, test leads and accessories that are not in use.
Use only correct Measurement Category (CAT), voltage, temperature, altitude, and amperage rated probes, test leads, and adapters for any measurement.
Beware of high voltages
Understand the voltage ratings for the probe you are using and do not exceed those ratings. Two ratings are important to know and understand:
- The maximum measurement voltage from the probe tip to the probe reference lead.
- The maximum floating voltage from the probe reference lead to earth ground.
These two voltage ratings depend on the probe and your application. Refer to the Specifications section of the manual for more information.
| WARNING:To prevent electrical shock, do not exceed the maximum measurement or maximum floating voltage for the oscilloscope input BNC connector, probe tip, or probe reference lead. |
