Programming Commands and Examples ESG Family Signal Generators
:FREQuency Subsystem
Reference Oscillator Source State
:ROSCillator:SOURCe:AUTO ON|OFF|1|0
:ROSCillator:SOURCe:AUTO?
This command sets the signal generator’s capability of automatically selecting between the
internal reference oscillator and an external reference oscillator to either on or off. When
this function is turned on, the signal generator detects when a valid reference signal is
present at the 10 MHz IN connector and automatically switches from internal to external
reference operation. Conversely, when this function is turned off, the signal generator uses
the internal reference only, even if an external reference is connected.
*RST Value: ON
Set Phase Reference
:PHASe:REFerence
This command sets the current output phase as a zero reference. Phase adjustments are
then set as relative to this zero reference.
Start Frequency
:FREQuency:STARt <val><unit>
:FREQuency:STARt?
This command sets the frequency of the first point in the sweep. The choices for the
variables <val> and <unit> may range from 100.0 kHz to the signal generator’s maximum
specified frequency.
*RST Value: signal generator’s maximum specified frequency.
Stop Frequency
:FREQuency:STOP <val><unit>
:FREQuency:STOP?
This command sets the frequency of the last point in the sweep. The choices for the
variables <val> and <unit> may range from 100.0 kHz to the signal generator’s maximum
specified frequency.
*RST Value: signal generator’s maximum specified frequency.
