R&S FSP Remote Control – Description of Commands
TRACe Subsystem
Example:
TRAC:IQ ON
' Switches on acquisition of I/Q data.
TRAC:IQ:SYNC ON
'Switches on synchronization of the aquision of I/Q measurement data with the
trigger time.
TRAC:IQ:SET NORM,10MHz,32MHz,EXT,POS,0,2048
'Reads 2048 I/Q values starting at the time of trigger.
'Filter type: NORMAL (analogue)
'RBW: 10 MHz
'Sample Rate: 32 MHz
'Trigger: external
'Slope: positive
TRAC:IQ:AVER ON
' Enables averaging of the recorded I/Q data..
TRAC:IQ:AVER:COUN 10
' Selects averaging over 10 data sets..
TRAC:IQ:DATA?
'Starts the measurement and reads out the averaged data.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A-T
This command is available from firmware version 1.32 or higher.
TRACe<1|2>:IQ:DATA:FORMat COMPatible | IQBLock | IQPair
This command sets the data output formatting (using the TRAC:IQ:DATA? command).
Parameter: COMPatible: 512k I data and 512k Q data is alternately transferred
IQBLock: First, all I and then all Q data is transferred
IQPair: I/Q data is transferred in pairs
Example:
"TRAC:IQ:DATA:FORM IQP"
Characteristics: *RST value: COMP
SCPI: device-specific
Mode: A
TRACe<1|2>:IQ:DATA:MEMory[:RF]? <offset samples>,<# of samples>
This command permits the readout of previously acquired (and frequency response corrected) I/Q data
from the memory, with indication of the offset related to the start of measurement and with indication
of the number of measurement values. Therefore a previously acquired data set can be read out in
smaller portions. The maximum amount of available data depends on the settings of command
TRACe:IQ:SET, the output format on the settings in the FORMat – subsystem.
The command requires that all requested measurement data be completely
retrieved before the device accepts any further commands.
If no baseband IQ data is available in the memory because the associated mea-
surement has not yet been started, the command generates a query error.
