96. 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 menu take effect immediately In front panel operation mode the voltage and frequency slew rates rate of change are always at their maximum of 2E5 V s and 2E5 Hz s Slew rate programming is only possible over the IEEE 488 RS232C LAN or USB bus On power up the AC source always reverts to the maximum slew rate for both voltage and frequency 4 7 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 4 7 3 Step Transients Step transients let you specify an alternate or trigger
