SENSe:ROSCillator:INTernal:POWer:STANdby
Syntax
[SENSe:]ROSCillator:INTernal:POWer:STANdby {OFF | ON}
[SENSe:]ROSCillator:INTernal:POWer:STANdby?
Description
This command controls whether standby power is provided to the optional internal oven-controlled oscil-
lator (OCXO), if present, when the front-panel power switch is in the standby mode.
l When ON is selected, the internal oven-controlled oscillator remains powered and stable in standby
mode as long as ac power is present or the optional internal battery power lasts. This increases power
consumption in standby, but the oscillator will be at full accuracy and stability immediately after
power-on.
l When OFF is selected, the internal oven-controlled oscillator is powered off in standby mode. This min-
imizes standby power consumption; however, this will power-cycle the oscillator. When powered on,
the oscillator's calibrated accuracy may be affected, and the oscillator may not be stable until the end
of the specified warm-up time. If the optional battery is present, you should select OFF before dis-
connecting the instrument from ac power for an extended period to prevent discharging the battery.
Power cycling the oven-controlled oscillator may affect instrument calibration accur-
acy.
Remarks
l The standby power setting is stored in non-volatile memory, and is unchanged after a Factory Reset
(*RST command) or an Instrument Preset (SYSTem:PRESet command).
l Standby power is disabled when the instrument is shipped from the factory or after a SYSTem:SECur-
ity:IMMediate command.
Return Format
The query returns the gate source: 0 (OFF) or 1 (ON).
Examples
The following example disables standby power:
