R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Remote Control – Description of Commands
Mode: A-T
SCPI: device-specific
TRACe:IQ:SRATe 400 Hz to 100 MHz
TRACe Subsystem
This command sets the sampling rate for the I/Q data acquisition. Thus the sample rate can be
modified without affecting the other settings.
Return value: 400 Hz to 100 MHz (326.4 MHz with the option R&S FSQ-B72)
sampling rates >81.6 MHz require a bandwidth of 50 MHz, set with the TRAC:IQ:
SET command.
Example: TRAC:IQ:SRAT 4MHZ
Characteristics: *RST value: 32 MHz
SCPI: device-specific
Mode: A-T
TRACe:IQ[:STATe] ON | OFF
For using these default settings with command TRAC:IQ:DATA? the following
minimum buffer sizes for the response data are recommended:
ASCII format: 10 kBytes
Binary format: 2 kBytes
If = CFILter, the sample rate is determined by the selected filter bandwidth.
In this case, the currently set sample rate can be determined using the
query command. Entering a value causes an execution error if =
CFILter.
This command switches the I/Q data acquisition on or off.
It is possible to combine I/Q data measurement with gated trigger function for following
settings:
• Sample rate 81.6 MHz
• Gate source EXTERN
The gate parameters (gate mode, gate polarity, gate delay, and gate length) are
configured by the subsystem SENSe:SWEep:EGATe, when TRACE:IQ:STATe is
set to ON.
All other measurement functions will be switched off as soon as the I/Q measurement
function is switched on. Additionally, a trace display is not possible in this
operating mode. Therefore all traces are set to "BLANK". Finally, split screen operation
will automatically be stopped.
Example: TRAC:IQ ON
'Switches on I/Q data acquisition
TRAC:IQ:ONL ON
'Switches the online output of the I/Q data on.
