[SENSe<1|2>:]ROSCillator:SOURce INTernal | EXTernal
This command controls selection of the reference oscillator.
If the external reference oscillator is selected, the reference signal must be connected to the rear
panel of the instrument.
Example: "ROSC:SOUR EXT"
Characteristics: *RST value: –
SCPI: conforming
Mode: all
[SENSe<1|2>:]ROSCillator[:INTernal]:TUNe 0 to 4095
This command defines the value for the tuning of the internal reference oscillator.
The reference oscillator should be tuned only if an error has been detected in the frequency accuracy
check. After rebooting the instrument, the factory-set reference frequency or the previously saved
reference frequency is restored.
Note: This command is only available at service level 1.
Example: "ROSC:TUN 128"
Characteristics: *RST value: –
SCPI: device-specific
Mode: all
[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.
Note: This command is only available at service level 1.
Example: "ROSC:TUN:SAV"
Characteristics: *RST value: –
SCPI: device-specific
Mode: all
