SENSe:ROSCillator Subsystem
This subsystem controls the reference oscillator. The suffix in SENSe<1|2> is not significant in this
subsystem.

:[SENSe<1|2>:]ROSCillator:SOURce INTernal | EXTernal
This command controls selection of the reference oscillator.
Example:
":ROSC:SOUR EXT"
Features: *RST value: –
SCPI: conforming
Modes: A, VA, BTS, MS
If the external reference oscillator is selected, the reference signal must be connected to the rear
panel of the instrument. *RST has no influence on this setting.
:[SENSe<1|2>:]ROSCillator:EXTernal:FREQuency 1MHz to 16MHz
This command defines the frequency of the external reference oscillator.
Example:
":ROSC:EXT:FREQ 5MHz"
Features: *RST value: 10MHz
SCPI: conforming
Modes: A, VA, BTS, MS
The value of the external reference frequency (1MHz to 16MHz) is rounded in steps of 1MHz.
:[SENSe<1|2>:]ROSCillator[:INTernal]:TUNe 0 to 4095
This command defines the value for the tuning of the internal reference oscillator.
Example:
":ROSC:TUN 128"
Features: *RST value: –
SCPI: device-specific
Modes: A, VA, BTS, MS
The reference oscillator should be tuned only if an error has been detected in the frequency accuracy
check. After PRESET or switching on the instrument, the saved value of the reference frequency is
restored.
:[SENSe<1|2>:]ROSCillator[:INTernal]:TUNe:SAVe
This command saves the new value for the tuning of the internal reference oscillator. The factory-set
value in the EEPROM is overwritten.
Example:
":ROSC:TUN:SAV"
Features: *RST value: –
SCPI: device-specific
Modes: A, VA, BTS, MS
