Optimizing Performance for All Models
Using an Output Offset, Reference, or Multiplier
When set to Auto, power search automatically executes when a significant instrument setting
changes. The Do Power Search feature enables you to decide when to execute a power search to
compensate for changes, such as temperature drift or a change in the external input.
Using an Output Offset, Reference, or Multiplier
Setting an Output Offset
Using an output offset, the signal generator can output a frequency or amplitude that is offset
(positive or negative) from the entered value.
RF Output = entered value – offset value
Displayed Value = output frequency + offset value
To set an offset:
— Frequency: Press Freq > Freq Offset > offset value > frequency unit.
— Amplitude: Press Amptd > More > Amptd Offset > offset value > dB.
Examples
When using the signal generator as a local oscillator (LO), you can use the offset to display the
frequency of interest, as illustrated below:

Entered (and displayed)
Value:
300 MHz 300 MHz 2 GHz The entered value must be positive.
Offset: 50 MHz −50 MHz −1 GHz An offset value can be positive or negative.
Output Frequency: 250 MHz 350 MHz 3 GHz
The signal generator alerts you if the
output frequency or amplitude is out of range.
