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 to the channel 1 output as shown below (the
frequency counter input should be terminated at 50 ).
2 Set the instrument to the output described in the table below and
measure the output frequency. Be sure the instrument output is enabled.
* With Option 010 OCXO the measurement error is ±1 Hz
3 Compare the measured frequency to the test limits shown in the table.
