RF Output Power Problems

RF Output Power Problems

Check the RF ON/OFF annunciator on the display. If it reads RF OFF, press RF On/Off to toggle the RF output on.

RF Output Power too Low

1.Look for an OFFS or REF indicator in the AMPLITUDE area of the display.

OFFS tells you that an amplitude offset has been set. An amplitude offset changes the value shown in the AMPLITUDE area of the display but does not affect the output power. The amplitude displayed is equal to the current power output by the signal generator hardware plus the value for the offset.

To eliminate the offset, press the following keys:

Amplitude > More (1 of 2) > Ampl Offset > 0 > dB.

REF tells you that the amplitude reference mode is activated. When this mode is on, the displayed

amplitude value is not the output power level. It is the current power output by the signal generator hardware minus the reference value set by the Ampl Ref Set softkey.

To exit the reference mode, follow these steps:

a.Press Amplitude > More (1 of 2).

b.Press Ampl Ref Off On until Off is highlighted.

You can then reset the output power to the desired level.

2.If you are using the signal generator with an external mixer, see “Signal Loss While Working with a Mixer” on page 190.

3.If you are using the signal generator with a spectrum analyzer, see “Signal Loss While Working with a Spectrum Analyzer” on page 192.

The Power Supply has Shut Down

If the power supply is not working, it requires repair or replacement. There is no user-replaceable power supply fuse. Refer to the Service Guide for instructions.
