Troubleshooting

No Modulation at the RF Output

There are three power search modes: manual, automatic, and span.

When Power Search is set to Manual, pressing Do Power Search executes the power search calibration routine

for the current RF frequency and amplitude. In this mode, if there is a change in RF frequency or amplitude, you will need to press Do Power Search again.

When Power Search is set to Auto, the calibration routine is executed whenever the frequency or amplitude of the RF output is changed.

When Power Search is set to Span, pressing Do Power Search executes the power search calibration routine over a selected range of frequencies at one time. The power search corrections are then stored and used whenever the signal generator is tuned within the selected range of frequencies.

No Modulation at the RF Output

Check the MOD ON/OFF annunciator on the display. If it reads MOD OFF, press Mod On/Off to toggle the modulation on.

Although you can set up and enable various modulations, the RF carrier is modulated only when you have also set Mod On/Off to On.

For digital modulation, make sure that I/Q Off On is set to On.
