R&S ESCI TRACe Subsystem
1166.6004.12 6.231 E-1
Examples:
"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.
'Filtertype:NORMAL (analog)
'RBW:1 MHz
'Sample Rate:4 MHz
'Trigger:External
'Slope:Positive
Characteristics: *RST values: NORM,3MHz,32MHz,IMM,POS,0,128
Note:
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
SCPI: device specific
Mode:A-T
TRACe<1|2>:IQ:SRATe 15.625kHz to 32MHz
This command sets the sampling rate for the I/Q data acquisition. Thus the sample rate can be
modified without affecting the other settings.
Value range: 15.625 kHz, 31.25 kHz, 62.5 kHz,
125 kHz, 250 kHz, 500 kHz,
1 MHz, 2 MHz, 4 MHz, 8 MHz, 16 MHz, 32 MHz
Example: "TRAC:IQ:SRAT 4MHZ"
Characteristics: *RST value: 32 MHz
SCPI: device specific
Mode: A-T
TRACe<1|2>:IQ[:STATe] ON | OFF
This command switches the I/Q data acquisition on or off.
Note: The I/Q data acquisition is not compatible with other measurement functions. Therefore all
other measurement functions will be switched off as soon as the I/Q measurement function
is switched on. Additionally a trace display is not possible in this operating mode. Therefore
all traces are set to "BLANK". Finally split screen operation will automatically be stopped.
Example: TRAC:IQ ON 'Switches on I/Q data acquisition
Characteristics: *RST value: OFF
SCPI: device specific
Mode:A-T
