Synchronizing Output Steps
Series N6700 User’s Guide

Set the Voltage or Current Trigger Levels
Next, use the following commands to program an output trigger level.
The output will go to this level when the trigger is received.
If you have a model that has multiple ranges, the selected triggered
voltage and current settings must be within the
same
range that the
output channel is presently operating in.
Front Panel:
SCPI Command:
Select
Transient\Step
. T
hen select
the Trig Voltage box. Enter a value and
press Select
.
Select the Trig Current box to set
current. Enter a value and press Select
.
To set a voltage and current trigger
level for output 1 use:
VOLT:TRIG 15,(@1)
CURR:TRIG 1,(@1)
Select the Transient Trigger Source
NOTE
An immediate trigger command from either the front panel or over the bus will
generate an immediate trigger regardless of the trigger source.
Unless you are using the front panel menu or a TRIG:TRAN command
to trigger the output, select a trigger source from the following:
Bus
Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
Pin <number>
Selects a pin on the external port connector as the trigger source. You can
specify pins 1, 2, or 3. The selected pin must be configured as a Trigger Input
in order to be used as a trigger source (see Appendix C)
Transient
<channel>
Selects the output channel’s transient system as the trigger source.
<channel> specifies the channel.
When you select a channel, you must also set up that channel’s transient
system to generate a trigger out signal. Refer to “Generating a Transient
Trigger Signal”.
Use the following commands to select a trigger source:
Front Panel:
SCPI Command:
To select Bus triggers, select
Transient\TrigSource
. Then select
Bus
.
To select Digital pin triggers, select
Transient\TrigSource
. Then select
one of the digital port pins.
To select Transient output triggers,
select
Transient\TrigSource
. Then
select one of the output channels.
To select Bus triggers for output 1:
TRIG:TRAN:SOUR BUS,(@1)
To select Digital pin triggers:
TRIG:TRAN:SOUR PIN<n>,(@1)
where n is the pin number.
To select Transient output triggers:
TRIG:TRAN:SOUR TRAN<n>,(@1)
where n is the output channel that
will generate the trigger signal.
