R&S FSP Remote Control – Description of Commands
TRACe Subsystem
<trigger slope>: Used trigger slope.
Values: POSitive | NEGative
<pretrigger samples>: Number of measurement values to be recorded before the
trigger point.
Range: -130559 (= -(128*1024-1-512)) to 130559 (= 128*1024-1-512)
(Negative values correspond to a trigger delay.)
<# of samples>: Number of measurement values to record.
Value range: 1 to 130560 (= 128*1024 – 512)
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
RFPower requires the TV and RF Trigger option R&S FSP-B6.
After selecting IFPower and RFPower, the trigger threshold can be set with com-
mand TRIG:LEV:IFP or TRIG:LEV:RFP.
For <trigger mode> = IMMediate the value must be 0.
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
