<trigger slope> Used trigger slope.
Values: POSitive
<pretrigger samples> Number of measurement values to be recorded before the
trigger point.
Range:–16253439 (= –(2
24
–1–512k –512)) ... 523775 (=
512*1024 – 512 – 1). Negative values correspond to a trigger
delay.
<# of samples> Number of measurement values to record.
Value range:1 ... 523776(= 512*1024 – 512)
Example
TRAC:IQ:SET NORM,10MHz,32MHz,EXT,POS,0,2048
Reads 2048 I/Q–values starting at the trigger point.
sample rate: 32 MHz
trigger: External
slope: Positive
TRAC:IQ:SET NORM,10MHz,4MHz,EXT,POS,1024,512
Reads 512 I/Q–values from 1024 measurement points before the trigger point.
filter type: NORMAL
RBW: 10 MHz
sample rate: 4 MHz
trigger: External
slope: Positive
Characteristics
*RST values: –,–,32MHz,IMM,POS,0,128
Note: For using these default settings with the TRACe<1|2>:IQ:DATA? command 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
This command sets the sampling rate for the I/Q data acquisition. Thus the sample rate can be
modified without affecting the other settings.
