SOURce:ROSCillator Subsystem
This subsystem contains the commands for setting the external and internal reference frequency.
Command Parameters Default

Remark
[SOURce:]ROSCillator:EXTernal:FREQuency 10 MHz Hz
[SOURce:]ROSCillator[:INTernal]:ADJust[:STATe] ON | OFF
[SOURce:]ROSCillator[:INTernal]:ADJust:VALue 0 ... 4095
[SOURce:]ROSCillator:SOURce INTernal | EXTernal
[SOURce:]ROSCillator:EXTernal:FREQuency 10 MHz
The command informs the instrument of the frequency of the external reference (10 MHz).
Example:
ROSC:SOUR EXT
'selects the external source. The reference must be input at the REF IN input.
ROSC:EXT:FREQ 10 MHz
'informs the instrument that the external reference frequency is 10 MHz'.

10 MHz - - Compliant
[SOURce:]ROSCillator[:INTernal]:ADJust[:STATe] ON | OFF
The command determines whether the calibrated (OFF) or a user-defined (ON) adjustment value is
used for fine adjustment of the frequency. With STATe ON, the instrument is no longer in the
calibrated state. However, the calibration value is not changed and the instrument resumes the
calibrated state after switching the Adjustment State to Off.
Example:
ROSC:SOUR INT
'selects the internal source.
ROSC:ADJ ON
'activates use of a user-defined adjustment value.
ROSC:ADJ:VAL 1400
'sets the adjustment value to 1400.
*RST value Resolution Options SCPI
OFF - -. Device-specific
[SOURce:]ROSCillator[:INTernal]:ADJust:VALue 0 ... 4095
The command specifies the frequency correction value (adjustment value).
Example:
ROSC:ADJ:VAL 1400
'sets the adjustment value to 1400.
*RST value Resolution Options SCPI
