-20GHz to 20GHz

0Hz

Explanation

 When is set in "Number" form, the default unit is Hz, for example,

20000. In addition, can also be set in "Number + Unit" form, for

example, 20kHz.

 The default unit of the return value is Hz.

 After the RF frequency offset is set, you can use the up/down direction keys or

knob to modify the offset at the current step. You can query or set the current

step using the

command.

 When the frequency offset is 0 Hz, the frequency displayed in the interface

(namely the setting frequency) is equal to the actual output frequency.

 When the frequency offset is not 0 Hz, the output frequency is determined by

the setting frequency and frequency offset. The three parameters satisfy the

equation: setting frequency (display frequency) = output frequency +

frequency offset. You can use the

command to query

and set the RF frequency.

Return Format

The query returns the RF frequency offset, for example, 20000.

Example

:FREQ:OFFS 20kHz
:FREQ:OFFS?
