Calibrating Jitter Systems
Periodic calibration of the jitter generation and measurement systems
is recommended to maintain best accuracy. You can execute built–in
Jitter Measurement calibration routines before making critical
measurements.
Run Jitter Measurement before runing Jitter Generation Calibration.
This Jitter Measurement calibration takes about 15 minutes for all
rates. You can calibrate one particular rate by selecting the
appropriate calibration routine.
If your CTS 850 test set supports a 45 Mb/s rate, this screen below
will show that rate in addition to all the others displayed.
