Using an Output Offset and Reference
Setting an Output Offset
Using an output offset, the source 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 (or power) + offset value
To set an offset:
— Frequency: Click Input/Output, RF Source, Frequency Setup, Freq Offset >
offset value > frequency unit keys.
— Amplitude: Click Input/Output, RF Source, Amplitude Setup, Amptd
Offset > offset value > dB keys.
Examples
When using the source as a local oscillator (LO), you can use the offset to
display the frequency of interest, as illustrated below:

Comments
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 source alerts you if the 
output frequency or amplitude is out of
range.
