frequencies above 10 GHz, the RF preselector might not be properly
centered. Press

Preselector
. The characterization will take several minutes and the analyzer
must not be interrupted during this time. If the analyzer 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 analyzer 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

allows the analyzer 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.
