<TriggerMode> IMMediate | EXTernal | IFPower | BBPower | PSE
Selection of the trigger source used for the measurement.
For details on trigger sources, see "Trg/Gate Source"
on page 268.
For IMM mode, gating is automatically deactivated.
*RST: IMM
<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]
Digital input: 0 to (MaxNofSamples -1); MaxNofSamples as
defined in Table 3-16
Range: 0 to (MaxPreTriggerSamples * 128 MHz/sample
rate).
*RST: 0
<NumberSamples> Number of measurement values to record (including the pretrig-
ger samples).
For digital input via the R&S Digital I/Q Interface (R&S FSV-B17)
the valid number of samples is described in Table 3-15.
If the I/Q bandwidth extension option R&S FSV-B160 is activa-
ted, the maximum number of samples is described in Chap-
ter 3.5.6.2, "Sample Rate and Maximum Usable Bandwidth (RF
Input)", on page 470.
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
