[SENSe<1|2>:]ROSCillator:EXTernal:FREQuency
1MHz to 20MHz
This command informs the instrument on the frequency of the external reference oscillator. This
frequency is used as starting point for the synchronization of the internal reference frequencies.
The value of the external reference frequency (1 MHz to 20 MHz) is rounded in steps of 1 Hz.
Example:
"ROSC:EXT:FREQ 5MHz"
Characteristics:
*RST value:
-
SCPI:
conforming
[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.
This command is only available at service level 1.
Example:
"ROSC:TUNE 128"
Characteristics:
*RST value:
–
SCPI:
device-specific
[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.
This command is only available at service level 1.
Example:
"ROSC:TUNE:SAV"
Characteristics:
*RST value:
–
SCPI:
device-specific
