Example:
TRAC:IQ:STAT ON
Enables acquisition of I/Q data
TRAC:IQ:SET NORM,10MHz,32MHz,EXT,POS,100,4096
Measurement configuration:
Sample Rate = 32 MHz
Trigger Source = External
Trigger Slope = Positive
Pretrigger Samples = 100
Number of Samples = 4096
INIT;*WAI
Starts measurement and wait for sync
FORMat REAL,32
Determines output format
To read the results:
TRAC:IQ:DATA:MEM?
Reads all 4096 I/Q data
TRAC:IQ:DATA:MEM? 0,2048
Reads 2048 I/Q data starting at the beginning of data acquisition
TRAC:IQ:DATA:MEM? 2048,1024
Reads 1024 I/Q data from half of the recorded data
TRAC:IQ:DATA:MEM? 100,512
Reads 512 I/Q data starting at the trigger point (<Pretrigger
Samples> was 100)
Usage:
Query only
TRACe<n>:IQ:DIQFilter <State>
This command is only available when using the Digital Baseband Interface (R&S FSV-
B17).
By default, a decimation filter is used during data acquisition to reduce the sample rate
to the value defined using TRACe<n>:IQ:SRATe.
If the filter is bypassed, the sample rate is identical to the input sample rate configured
for the Digital I/Q input source (see INPut:DIQ:SRATe on page 762).
Suffix:

Parameters:
<State> ON | OFF
ON
The digital I/Q filter bypass is on, i.e. no filter or resampler is
used during I/Q data acquisition.
OFF
The filter bypass is off, i.e. decimation filter and resampler are
used during I/Q data acquisition.
*RST: OFF
Example: TRAC:IQ:DIQF ON
