This subsystem is used to synchronize the analyzer's actions (in particular, the start of a measurement sequence) with events.
Command tree: TRIGger<Ch>
Sets a delay time between the trigger event and the start of the measurement (Trigger Delay).

|
Range [def. unit] |
0 s to 13680 s [s]. UP and DOWN increment/decrement the trigger delay in 10 ms steps. |

Device-specific, command or query
|
|
Example: |
See TRIGger<Ch>[:SEQuence]:HOLDoff:MODE
|
Qualifies whether the trigger delay is valid for all physical ports (including external generator) or source port-specific. This setting is available if the triggered measurement sequence is a partial measurement (TRIGger<Ch>[:SEQuence]:LINK 'PPOint').
|
<Ch> |
Channel number
|
|
Parameters |
PALL – Same trigger delay at all ports (TRIGger<Ch>[:SEQuence]:HOLDoff) PSPecific – Port-specific trigger delay defined via TRIGger<Ch>[:SEQuence]:HOLDoff:PORT<Pt> (for physical analyzer ports) or TRIGger<Ch>[:SEQuence]:HOLDoff:GENerator<Gen> (for external generators). |
|
*RST value |

Gen. 1', 'SME02', 'gpib0', '21' Configure an R&S SME02 generator as external generator no. 1. TRIG:HOLD:PORT1 0.001; PORT2 0.002; GEN1 0.003 Define port-specific trigger delays at the analyzer ports 1 and 2 and at the external generator port 1.

|
|
<delay> |

SCPI, Command Types |
Device-specific, command or query
|
|
Example: |
See TRIGger<Ch>[:SEQuence]:HOLDoff:MODE
|
Selects the Triggered Meas. Sequence. The identifier for the sequence is a string variable.
|
<Ch> |
Channel number
|
|
'SWEep' | |
Trigger event starts an entire sweep. |
|
'SEGMent' | |
Trigger event starts a sweep segment, if segmented frequency sweep is active (see example below). If another sweep type is active, the trigger event starts an entire sweep. |
|
'POINt' | |
Trigger event starts measurement at the next sweep point. |
|
'PPOint' |
Trigger event starts the next partial measurement at the current or at the next sweep point. |
|
*RST value |
'SWEep'
|
|
SCPI, Command Types |
Confirmed, command or query. The query returns the complete string; see example below.
|
|
Example: |
SEGM:ADD; :SWE:TYPE SEGM Select segmented frequency sweep. TRIG:LINK 'SEGM' Select a trigger segment as triggered measurement sequence. TRIG:LINK? Query the triggered measurement sequence. The response is 'SEGMENT'.
|
Selects the trigger source for pulsed measurements (option R&S ZVA-K27) using an Extension Unit R&S ZVAXxx equipped with a Pulse Modulator option (R&S ZVAX-B71 or Z&S ZVAX-B73).
