(Read-Write) Specifies whether the PNA trigger source is set to Internal (continuous) or Manual.

• For SIMPLE, single-triggering of a single channel, use Sens:Sweep:Mode SINGle which sets the number of trigger signals each channel will ACCEPT (Continuous, Groups, Single, or HOLD - none.)

• This command is a subset of TRIG:SEQ:SOURce, which can also set the trigger source to External.

• See a map of user interface to SCPI triggering commands.

• For more information on triggering, see the PNA Trigger Model.

• See the Example program:  Triggering the PNA using SCPI.

Parameters

<boolean>

ON (or 1) - Internal (continuous) trigger.

OFF (or 0) - Manual sweep. Use INIT:IMMediate to send a trigger signal

Examples

INIT:CONT ON
initiate:continuous off

Query Syntax

INITiate:CONTinuous?

Return Type

Boolean (1 = ON, 0 = OFF)

Default

ON

(Write-only) Stops the current sweeps and immediately sends a trigger. (Same as Trigger! on the PNA front panel).

• This command requires Trigger:Source to be set to Manual. This causes ONE trigger signal to be SENT each time INIT:IMM is issued.

• For SIMPLE, single-triggering of a single channel, use Sens:Sweep:Mode SINGle which sets the number of trigger signals each channel will ACCEPT (Continuous, Groups, Single, or HOLD - none.)

See the Example program:  Triggering the PNA using SCPI

Note: An SMC Fixed Output measurement cannot be triggered using this command. For more information, see the example program.

To trigger ALL channels in turn:

Set ALL channels to Sens<ch>:Sweep:Mode Continuous.  The <ch> argument in INIT<ch>:IMM is ignored.

Then…

• TRIG:SCOP ALL triggers ALL channels (in sequence) each time Init:Imm is sent.

• TRIG:SCOP CURRent triggers ONLY the NEXT channel each time Init:Imm is sent.

To trigger ONLY a specified channel:

1. Set ALL channels to Sens<ch>:Sweep:Mode HOLD

2. Send TRIG:SCOP CURRent

3. Send Init<ch>:Imm where <ch> is the channel to be triggered.

Advanced   Situations that require some channels to be in CONT and others in HOLD are rare. The following describes the behavior of the Init:Imm command in these situations:

When Trigger:Scope = Global:

• If the SPECIFIED <cnum> channel is in hold mode, it is put in single trigger (accepts 1 trigger signal) and goes to the end of the queue of channels to be triggered. The other 'non-hold' channels are triggered. The next Init:Imm triggers the specified channel first.

For example: ch1 is in Hold, ch2 and ch3 are in CONT and we send INIT1:IMM

1. • On the first INIT:IMM, ch2 and ch3 is triggered.

   • next INIT:IMM, ch1, ch2, ch3 is triggered.

   • next INIT:IMM, ch2 and ch3 is triggered.

   • next INIT:IMM, ch1, ch2, ch3 is triggered, and so forth.

When Trigger:Scope = Channel

• Only ONE channel is triggered for each issued INIT<ch>:IMM command.

• If the specified channel is in hold, it is put in single trigger (accepts 1 trigger signal) and goes the end of the queue of channels to be triggered as in the 'Global' example.
