<TriggerSlope>
POSitive | NEGative
Used trigger slope.
*RST:
POS
<PretriggerSamp>
Defines the trigger offset in terms of pretrigger samples. Nega-
tive values correspond to a trigger delay.
This value also defines the interval between the trigger signal
and the gate edge in samples.
Range:
RF input without gating: 0 to (200 MS - 1)
RF input with gating: 0 to [(200 MS * SR/128 MHz)-1]
Range:
0 to (MaxPreTriggerSamples * 128 MHz/sample
rate).
*RST:
0
<NumberSamples>
Number of measurement values to record (including the pretrig-
ger samples).
Range:
1 ... 209715200(= 200*1024*1024);
*RST:
128
Example:
TRAC:IQ:SET NORM,10 MHz,32 MHz,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,10 MHz,4 MHz,EXT,POS,1024,512
Reads 512 I/Q-values from 1024 measurement points before the
trigger point.
sample rate = 4 MHz
trigger = External
slope = Positive
Manual operation:

TRACe<n>:IQ:SRATe
<SampleRate>
This command sets the final user sample rate for the acquired I/Q data. Thus, the sam-
ple rate can be modified without affecting the other settings.
Note
: The smaller the user sample rate, the smaller the usable I/Q bandwidth, see
