ESG Family Signal Generators Programming Commands and Examples
:FREQuency Subsystem
:FREQuency Subsystem
The frequency subsystem is used to set the controls and the parameters associated with
carrier signal frequency.
Continuous Wave Frequency
:FREQuency[:CW] <val><unit>
:FREQuency[:CW]?
:FREQuency:FIXed <val><unit>
:FREQuency:FIXed?
This command sets the signal generator’s CW output frequency. The choices for the
variable <val> may range from 100 kHz to the signal generator’s maximum specified
output frequency.
The current RF output frequency is always shown in the frequency area of the display
(unless you have altered the display by turning on frequency reference mode, entering an
offset or a multiplier, or if a frequency sweep is selected). Use this command to change the
RF output frequency. Frequency becomes the active function and the current value is also
shown in the active entry area of the display.
At *RST, this value is set to the signal generator’s maximum specified output frequency.
Fixed Frequency
:FREQuency:FIXed <val><unit>
:FREQuency:FIXed?
This command sets the carrier frequency for the signal generator’s RF output. The choices
for the variables (depending on your signal generator’s model number) <val> and <unit>
range from 100 kHz (minimum) to 1 GHz, 2 GHz, 3 GHz, or 4 GHz (maximum).
*RST Value: signal generator’s maximum specified output frequency.
Frequency Mode
:FREQuency:MODE CW|FIXed|LIST
:FREQuency:MODE?
This command sets the frequency mode of the signal generator. The choices are CW or
Fixed, and List.
*RST Value: CW
