12 Press the Perform Cal Step softkey to enter the data into the
counter and initiate the reference oscillator calibration.
If the calibration step PASSES, after a few seconds the counter
momentarily displays:
“Calibration step succeeded.”
–The Cal Count on the screen increments.
If the calibration step FAILS, after a few seconds the counter displays:
“Calibration step failed
After several seconds, “Calibration step failed” is cleared.
–The Cal Count does not increment.
NOTE If the calibration fails, the current calibration constants remain
unchanged.
13 If the calibration fails (“Calibration step failed”), first verify the
input frequency is correct and the source output is connected and
turned on. Then, refer to the troubleshooting procedures on
page 150.
14 To check for error messages, refer to the “Remote Oscillator
Calibration Summary” below for information on how to read the
error message(s) from a remote computer.
NOTE If you do not have a remote computer available (requires a LAN,
USB or GPIB interface) or are not proficient at programming,
contact the nearest Agilent Service Center for information and
help on sending the counter to Agilent for repair and/or
calibration.
NOTE If you are able to read the error message(s), consult “Error
Messages” starting on page 163 for what to do after receiving a
