 Network Analyzers using TRVNA software

The trigger system operates at the analyzer level.

The Analyzer can be in one of the following three states:

•Stop — the Analyzer waits for the trigger system to enter the Waiting for Trigger state.

•Waiting for Trigger — measurement stops, the Analyzer waits for the trigger signal. If the Internal trigger source (see Trigger Source) is selected, it is automatically generated.

•Measurement Cycle — all channels are measured in turn.

The figure below shows the states of the Analyzer, and the transitions between them.

Analyzer States and Transitions

The table below describes the transitions between analyzer states.

SYSTem:PRESet, *RST

Abort of the current measurement cycle.

ABORt

Changing Analyzer settings by user or by the SCPI command.

For example: Stimulus > Start

For example: SENSe:FREQuency:STARt

When the trigger initiation mode has been set to Hold.

Stimulus > Trigger > Hold

INITiate:CONT OFF

1.2

Stop –> Waiting for Trigger

Every time if the trigger initiation mode has been set to Continuous.

Stimulus > Trigger > Continuous

INITiate:CONT ON

Once when the trigger initiation mode has been set to Single.

Stimulus > Trigger > Single

INITiate

1.3

Waiting for Trigger  –> Measurement Cycle

Automatically, if the trigger source is set to Internal.

Stimulus > Trigger > Trigger source > Internal

TRIGger:SOURce INTernal

At a signal arrival at the external trigger input, if the trigger source is set to External.

(except TR1300)

Stimulus > Trigger > Trigger source > External

TRIGger:SOURce EXTternal

Upon receipt of SCPI command, if the trigger source is set to Bus.

Stimulus > Trigger > Trigger source > Bus

TRIGger:SOURce BUS

TRIGger:SINGle, TRIGger, *TRG

1.4

Measurement Cycle –> Waiting for Trigger

At the end of a measurement cycle, when the trigger initiation mode has been set to Continuous.

Stimulus > Trigger >  Continuous

INITiate:CONT ON

After measuring a point, when the On Point trigger function is active.

(except TR1300)

Stimulus > Trigger > Ext Trigger > Event > On Point

1.5

Measurement Cycle –> Stop

At the end of a measurement cycle, when the Continuous trigger initiation mode is disabled.
