R&S FSP Remote Control – Description of Commands
SENSe Subsystem
6.200 Operating Manual 1164.4556.12 - 06
[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:TUN:SAV"
Characteristics: *RST value: –
SCPI: device-specific
Mode: A
[SENSe<1|2>:]ROSCillator:SOURce INTernal | EXTernal | EAUTo
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.
As of firmware version 4.4x, you can you also select EAUTo. This paramater selects an external
reference signal, but switches to the internal reference signal if no external reference is detected. If the
external reference oscillator is selected (EXT | EAUT), the reference signal must be connected to the
rear panel of the instrument.
The reference settings are not changed after a preset.
Example:
"ROSC:SOUR EXT"
Characteristics: *RST value: –
SCPI: conform
Mode: A
*RST is not influencing this parameter.
[SENSe<1|2>:]ROSCillator:SOURce:EAUTo?
This command queries the current source of the reference signal, if the external reference source EXT
(INT) is used. The command returns INT if the internal reference source is used and EXT for an
external reference source.
This command is a query and therefore has no *RST value.
Example:
"ROSC:SOUR:EAUT?"
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
INTernal Uses the internal reference signal.
EXTernal Uses the external reference signal.
EAUTo Uses the external reference signal, but automatically switches to the internal
reference signal, if no external reference signal is detected. Note that you have
to change the reference source back to EXT and EAUT once the connection to
the external reference is reestablished.
You can query the current status with [SENSe<1|2>:]ROSCillator:SOURce:
EAUTo?
