Improving Accuracy with Self-Calibration Routines

Performing the Tracking Generator Self-Calibration

Routine

(Option 011 only)

In order for the tracking generator to meet its specifications, allow the cable TV analyzer to warm up for 30 minutes after being turned on before attempting to make any calibrated measurements. Be sure to calibrate the cable TV analyzer and the tracking generator only after the cable TV analyzer has met operating temperature conditions.

N O T E

Since the tracking-generator self-calibration routine uses the absolute amplitude level of the cable TV

analyzer, the cable IV analyrer amplitude should be calibrated prior to using CAL TRK GEN

1.To calibrate the tracking generator, connect the tracking generator output (RF OUT 75 0) to the cable TV analyzer INPUT 75 0 connector, using an appropriate cable and adapters.

N O T E

A low-loss cable should be used for accurate calibration. Use the 75 fI cable shipped with the cable TV analyzer.
