Transient Programming
5.5.1
Introduction
Transient programming provides a precise timing control over output voltage and frequency changes. This
mode of operation can be used to test a product for susceptibility to common AC line conditions such as
surges, sags, brownouts and spikes. By combining transient programming with custom waveforms,
virtually any AC condition can be simulated on the output of the AC source.
The default voltage mode is FIXED which means the output voltage is constant and remains at the level
set by the user. Changes made to the output voltage made from the PROGRAM 1 menu take effect
immediately. In front panel operation mode, the voltage and frequency slew rates (rate of change) are
always at their maximum of 1E9 V/s and 1E9 Hz/s. Slew rate programming is only possible over the
remote control interface. On power up, the AC source always reverts to the maximum slew rate for both
voltage and frequency.
5.5.2
Using Transient Modes
The voltage can be programmed in the following transient operating modes:
STEP
causes the output to permanently change to its triggered value.
PULSE
causes the output to change to its triggered value for a specific time, as
determined by the Pulse menu parameters.
LIST
causes the output to sequence through a number of values, as determined by
points entered in the List menu.
FIXED
disables transient operation for the selected function.
5.5.3
Step Transients
Step transients let you specify an alternate or triggered voltage level that the AC source will apply to the
output when it receives a trigger. Because the default transient voltage level is zero volts, you must first
enter a triggered voltage before you can trigger the AC source to change the output amplitude. Step
transients can only be programmed through the bus, not the front panel. Refer to the SCPI Programming
Manual for more information about programming Step transients and triggers.
