Internal Timebase Verification
This test verifies the output frequency accuracy of the instrument.
All output frequencies are derived from a single generated frequency.
1 Connect a frequency counter as shown below (the frequency counter
input should be terminated at 50
Ω).
2 Set the instrument to the output described in the table below and
measure the output frequency. Be sure the instrument output is enabled.
3 Compare the measured frequency to the test limits shown in the table.
