Optimize Performance
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 fre offset value
To set an offset:

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:

The signal generator alerts you if the
output frequency or amplitude is out of range.
