TRACe Subsystem R&S ESCI
1166.6004.12 6.232 E-1
TRACe<1|2>:IQ:SYNChronize[:STATe] ON | OFF
This command switches on or off the synchronization of the start of I/Q data acquisition to the trigger
event. Prior to this command, I/Q data acquisition has to be switched. The sampling rate must be 32
MHz. The synchronization ensures the correct calculation of I/Q average values as the data
aquisition is always started with the same phase reference in relation to the trigger event.
Note: This command is not supprted for sampling rates other than 32 MHz.
Example:
"TRAC:IQ ON" 'Switches on I/Q data acquisition
"TRAC:IQ:SYNC ON ON" 'Switches on synchronization of I/Q data acquisition to the trigger
event
"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:AVER ON 'Enables averaging of the I/Q measurement 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: ON
SCPI: device specific
