Synchronizing Output Steps

The transient system lets you step the output voltage and current up or down in response to triggered events. To generate a triggered output step you must:

1.Enable the output to respond to trigger commands.

2.Set the voltage or current trigger levels.

3.Select the transient trigger source.

4.Initiate the trigger system and provide a trigger signal.

Enable the Output to Respond to Trigger Commands

First, you must enable the output to respond to trigger commands. Unless an output is enabled to respond to triggers, nothing will happen even if you have programmed a trigger level and generated a trigger for the output.

Use the following commands to enable an output to respond to triggers:

 

 

Front Panel:

SCPI Command:

 

 

Select Transient\Mode.

To enable the voltage function on

 

 

For voltage step triggering, set the

output 1 to respond to triggers, use:

 

 

Voltage mode to Step. For current

VOLT:MODE STEP,(@1)

 

 

 

 

 

step triggering, set the Current mode

To enable the current function on

 

 

output 1 to respond to triggers, use:

 

 

to Step. Then press Select.

 

 

CURR:MODE STEP,(@1)

 

 

 

 

 

 

 

 

In Step mode, the triggered value becomes the immediate value when the

NOTE

 

 

trigger is received. In Fixed mode, trigger signals are ignored; the immediate

values remain in effect when a trigger is received.

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.

To set a voltage and current trigger

Select the Trig Voltage box to set

level for output 1 use:

the voltage. Select the Trig Current

VOLT:TRIG 15,(@1)

box to set the current. Enter a value

CURR:TRIG 1,(@1)

and press Select.
