This subsystem is used to synchronize the analyzer's actions (in particular, the start of a measurement sequence) with events.

TRIGger<Ch>[:SEQuence]:HOLDoff <numeric_value>

Sets a delay time between the trigger event and the start of the measurement (Trigger Delay).

<Ch>

Channel number. If unspecified the numeric suffix is set to 1.

 

<numeric_value>

Delay time.  

Range [def. unit]

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

*RST value

0 s

 

SCPI, Command Types

Confirmed, command or query

 

Example:

TRIG:SOUR TIM
Activate internal timer as trigger source.

TRIG:HOLD UP
Set a delay time of 10 ms.

 

 


TRIGger<Ch>[:SEQuence]:LINK
'POINT' | 'SWEEP' | 'PPOINT' | 'SEGMENT'

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

 

Example:

SEGM:ADD; SWE:TYPE SEGM
Select segmented frequency sweep.

TRIG:LINK 'SEGM'
Select a trigger segment as triggered measurement sequence.

 

 


TRIGger<Ch>[:SEQuence]:SLOPe
POSitive | NEGative

Qualifies whether the trigger event occurs on the rising or on the falling edge of the external TTL trigger signal.

<Ch>

Channel number.

 

POSitive |

Rising edge.

NEGative

Falling edge.

*RST value

POSitive

 

SCPI, Command Types

Confirmed, command or query

 

Example:

TRIG:SOUR EXT
Activate external signal as trigger source.

TRIG:SLOP NEG
Trigger on the negative edge of the (external TTL) trigger signal.

 

 


TRIGger<Ch>[:SEQuence]:SOURce
IMMediate | EXTernal | TIMer | MANual

Selects the source for the events that the analyzer uses to start a sweep.

<Ch>

Channel number.

 

IMMediate

Free run measurement without waiting for trigger events

EXTernal

Trigger by external signal applied to pin 2 of the USER CONTROL connector on the rear panel.

TIMer

Periodic internal trigger signal. The period of the timer is specified by the TRIGger[:SEQuence]:TIMer command.

MANual

Trigger signal generated by pressing the Manual Trigger softkey.  

 

 

*RST value

IMMediate

 

SCPI, Command Types

Confirmed, command or query.

 

Example:

TRIG:SOUR MAN
Activate manual trigger mode. The analyzer starts the next sweep when the Manual Trigger softkey is pressed.

 

 


TRIGger<Ch>[:SEQuence]:TIMer <numeric_value>

Sets the period of the internal periodic signal that can be used as a trigger source (TRIGger<Ch>[:SEQuence]:SOURce TIMer).

<Ch>

Channel number. If unspecified the numeric suffix is set to 1.

 

<numeric_value>

Timer period  

Range [def. unit]

1E-005 s to 13680 s [s]. UP and DOWN increment/decrement the timer period in 10 ms steps.

*RST value

1 s

 

SCPI, Command Types

Confirmed, command or query

 

Example:

TRIG:SOUR TIM
Activate internal timer as trigger source.

TRIG:TIM 0.1
Set a timer period of 100 ms.
