R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Remote Control – Description of Commands
6.12.1 INPut:DIQ Subsystem
The INPut:DIQ subsystem controls the digital baseband input.
This subsystem is available only with option R&S FSQ-B17.
INPut Subsystem
INPut:DIQ:CDEVice?
This command queries the current configuration and status of the Digital Baseband input of option
R&S FSQ-B17. The returned string includes the name of the connected device, the serial number of
this device, the port name and the sample rate, separated by comma, e.g. “AMU200A,100266,Out A,
80000000.0”.
The suffix is irrelevant.
Example: "INP:DIQ:CDEV?"
queries the current input configuration.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is a query and therefore has no *RST value.
INPut:DIQ:RANGe:AUTO ON | OFF
This command controls the auto set function of the digital baseband input full scale value.
Depending on the digital baseband signal source, the full scale value of the I/Q data is passed to the
R&S FSQ LVDS input interface.
If the full scale level of the signal source is outside the R&S FSQ supported range, it shows the “BDI”
enhancement label. The “BDI” label is also visible if the signal source does not support automatic
matching.
The suffix is irrelevant.
The command is available with option R&S FSQ-B17.
Parameter: ON
Automatically matches the full scale value of the digital baseband input to that of
the signal source.
OFF
The R&S FSQ does not match the full scale value. You can set it manually with
“INPut:DIQ:RANGe[:UPPer]”.
Example: "INP:DIQ:RANG:AUTO OFF"
disbales automatic matching of the full scale value.
"INP:DIQ:RANG 1.2"
sets the voltage to 1.2 V.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
