Troubleshooting
Check the Basics
— If the previously performed alignments did not resolve the problem, press
System, Alignments, Restore Align Defaults. Then press System,
Alignments, Align Now, Align Now All.
— If the instrument exhibits large amplitude errors (> 10 dB) especially at
frequencies above 10 GHz, the RF preselector might not be properly
centered. Press AMPTD, Signal Path, Presel Center. If the signal amplitude
error is corrected, the preselector characterization should be performed.
Press System, Alignments, Advanced, Characterize Preselector. The
characterization will take several minutes and the instrument must not be
interrupted during this time. If the instrument is interrupted during the
characterization process, the characterization data will be destroyed and it
will be necessary to perform the entire process again.
— Is the instrument displaying an error message? If so, refer to the Instrument
Messages Guide.
— Check if the external frequency reference is selected but not available.
Verify that it is selected by pressing Input/Output, Freq Ref Input. If
External is selected, changing the setting to Sense allows the instrument to
sense the presence of an external reference and use it only if it is available.
The frequency of the reference should be set correctly.
— If you are using a Windows program other than the instrument application,
you may notice it running slow. Place the instrument application in single
sweep/measurement.
