Programming Manual

5.5.1 Transient System Model

When a trigger is received in step or pulse modes, the triggered functions are set from their

IMMediate to their TRIGgered value. In Step mode, the triggered value becomes the immediate

value. In Pulse mode, the functions return to their immediate value during the low portion of the

pulse.

If there are no further pulses, the immediate value remains in effect. In List mode, the functions

remain at the last list value at the completion of the list.

You can not mix STEP, PULSe, and LIST modes among functions.

5.5.2 Step and Pulse Transients

Step 1: Set the functions that you do not want to generate transients to FIXed mode. A

convenient way to do this is with the *RST command. Then set the mode of the function that will

generate the transient to STEP or PULSe as required. For example, to enable the voltage

function to generate a single triggered output voltage change, use:

*RST

VOLTage:MODE STEP

Step 2: Set the triggered level of the function that will generate the transient. For example, if the

previously programmed voltage function is going to step the output voltage amplitude to 135

volts upon reciept of a trigger, use:

VOLTage:TRIGger 135

Step 3: Select the trigger source that will generate the trigger. For example, to select the

Immediate use:

TRIGger:SOURce IMM

Trigger sources are discussed in detail under “Triggering Output Changes”

Step 4: Only perform this step if you have selected PULSE as the transient mode in Step 1.

Specify the pulse count, the pulse period, and then either the duty cycle or the pulse width using

the following commands:

PULSe:COUNt 1 specifies 1 output pulse

PULSe:PERiod 1 specifies a pulse period of 1 second

PULSe:DCYCle 50 specifies a duty cycle of 50%

PULSe:WIDTh .5 specifies a pulse width of .5 seconds (not necessary in this case since a

duty cycle has already been specified)

Step 5: Initiate the transient trigger system to enable it to receive a trigger. To enable the trigger

system for one transient event use:

INITiate

Example

The following example programs a voltage dropout for 2 seconds. The dropout is triggered by

IEEE-488 bus trigger.

*RST Begin at power-on state

VOLT 120 Set initial output voltage (immediate-level)

OUTP ON Enable the output

VOLT:MODE PULS Enable output to generate pulses when triggered

VOLT:TRIG 0 Set the voltage dropout (triggered level)

PULS:WIDT 2 Set pulse width for 2 seconds
