3-49. Time Marker Verification
This procedure uses the following equipment:
•
PM 6680 Frequency Counter with a prescaler for the Channel C input
(Option PM 9621, PM 9624, or PM 9625) and ovenized timebase (Option PM 9690
or PM 9691)
•
BNC(f) to Type N(m) adapter
•
N to BNC cable supplied with the Scope Calibrator
Set the PM 6680’s FUNCTION to measure frequency with auto trigger, measurement
time set to 1 second or longer, and 50
Ω
impedance.
Set the Calibrator Mainframe to Marker mode. Press on the Calibrator Mainframe
to activate the output. Then follow these steps to for each period listed in Table 3-23.
