RF Output
RF Output
No RF Output
—Check the RF Output On/Off key (In RF Source tab). If it is off, turn the RF
Output On to turn the output on (selection is underlined).
— Ensure that the amplitude is set within the source range.
— If the transceiver is playing a waveform, ensure that marker polarity and
routing settings are correct (see “Saving Marker Polarity and Routing
Settings” on page 35).
Power Supply Shuts Down
If the power supply does not work, it requires repair or replacement. If you are
unable to service the transceiver, send the transceiver to an Keysight service
center for repair (see “Contacting Keysight Technologies” on page 52).
No Modulation at the RF Output
Check the Modulation On/Off key, and ensure it is set to on.
RF Output Power too Low
— Check to see if the amplitude offset is set and if necessary, reset to 0 dB:
Choose Input/Output from the drop-down panel followed by Amplitude
Setup key of RF Source tab. Set Amptd Offset to 0 dB. See also “Setting an
Output Offset” on page 22.
