NOTES
Chapter 1 Performance Tests
Operational Verification
Set the first Synthesizer (the one connected to the Counter's rear-panel
Reference 10MHz connector) to output a 10 MHz, 1V rms, sine-wave
signal.
Set the second Synthesizer (the one connected to the CHANNEL 1 input) to
output a 2 MHz, 100 mV rms, sine-wave signal.
Press and release the Counter's Reset/Local key.
Verify that the Counter displays a reading of approximately 2 MHz and
that the Ext Ref annunciator is activated.
Mark Pass or Fail for Test 4 in the Performance Test Record on page 1-30.
This completes the Operational Verification.
If you intend to perform the Complete Performance Tests next, do not
•
disconnect the cable from the Counter's Reference 10MHz connector.
This connection is used in the Complete Performance Tests.
•
Do not turn off the Counter if you intend to perform the Complete
Performance tests. Turning the Counter off and back on resets the
reference oscillator (REF OSC) selection to internal (INT) and the
channel selection to CHANNEL 2.
