User-installed, Oscilloscope-resident Disk Drive Measurement Package

Design, manufacturing and failure analysis engineers at disk drive companies; silicon vendors who design read-channel components; read/write head and media manufacturers - all desire to make measurements that are specific to their industry. Performing measurements on disk drive signals that comply with the IDEMA standards is crucial to meeting their objectives.

Tektronix now offers a solution that provides custom disk drive measurements for the industry leading TDS oscilloscopes. Peak detect measurements include track average amplitude positive (TAA+), track average amplitude negative (TAA-), track average amplitude total (TAA), 50% pulse width positive (PW50+), 50% pulse width negative (PW50-), 50% pulse width (PW50), overwrite and resolution. Timing measurements include time - trough-to-peak, and time - peak-to-trough. PRML measurements include autocorrelation non-linear transition shift and signal-to-noise ratio. Voltage and time asymmetry measurements are available for MR head designers. Measurement statistics are also available.

TDSDDM1 Disk Drive Measurement software is a software package from Tektronix that delivers industry-specific disk drive measurements. It comes on floppy disks, is easily installed into a TDS500D/600C/700D oscilloscope and doesn't require any external processing or connections. After installation, the application is accessible from the front panel.
