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.
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 160.
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.
If the calibration fails, the current calibration constants remain unchanged.
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 Keysight
Service Center for information and help on sending the counter to Keysight for
repair and/or calibration.
If you are able to read the error message(s), consult “Error Messages” on
page 174 for what to do after receiving a specific calibration error message.
