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

return to their immediate value at the completion of the list.

You can mix FIXed, STEP, PULSe, and LIST modes among most functions. When a trigger is

received, each function will react in a manner defined by its mode. However, this is subject to the

following limitation to ensure the proper output voltage in all cases:

The ac voltage, waveform shape, and voltage slew functions cannot be set to Step or Pulse mode

if one of them is set to List mode.

6.5 Step and Pulse Transients

Proceed as follows to setup step and pulse transients:

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
