Input C Check
To verify the specification of the different RF
prescalers (Input C), use the following basic
test setup:
–
Connect the output of a signal generator
covering the specified frequency range to
the RF input of the counter.
–
Connect the 10 MHz REF OUT from the
generator to the EXT REF IN on the rear
panel of the counter.
