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:EGATe <State>
Activates or deactivates the gate function for IQ data measurements. This command is
only valid for TRAC:IQ ON and trigger modes "EXT" and "IFP". The gate trigger is
specified using
TRACe<n>:IQ:SET
on page 858. For details see Chapter 11.6.2, "I/Q
Gating" , on page 867.
