R&S ESU Remote Control – Description of Commands
TRACe Subsystem
Example: "TRAC:IQ:SET NORM,10MHz,32MHz,EXT,POS,0,2048"
'Reads 2048 I/Q-values starting at the trigger point.
'Filtertype: NORMAL (analog)
'RBW: 10 MHz
'Sample Rate: 32 MHz
'Trigger: External
'Slope: Positive
"TRAC:IQ:SET NORM,1MHz,4MHz,EXT,POS,1024,512"
'Reads 512 I/Q-values from 1024 measurement points before the trigger point.
'Filter type: NORMAL (analog)
'RBW: 1 MHz
'Sample Rate: 4 MHz
'Trigger: External
'Slope: Positive
Characteristics: *RST values: NORM,3MHz,32MHz,IMM,POS,0,128
SCPI: device-specific
Mode: A-T
TRACe<1|2>:IQ:SRATe 10.0 kHz to 81.6 MHz
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: 10.0 kHz to 81.6 MHz
Example: TRAC:IQ:SRAT 4MHZ
Characteristics: *RST value: 32 MHz
SCPI: device-specific
Mode: A-T
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 <filter type> = CFILter, the sample rate is determined by the selected filter band-
width. In this case, the currently set sample rate can be determined using the
query command. Entering a value causes an execution error if <filter type> =
CFILter.
