8.1.1.3 List Transients
List transients provide the most versatile means of controlling the output in a specific manner as they allow
a series of parameters to be programmed in a timed sequence. Figure 8-3 shows a voltage output
generated from a list. The output shown represents three different AC voltage steps: 160 volts for
33 milliseconds, 120 volts for 83 ms, and 80 volts for 150 ms, separated by three intervals of zero volts for
67 ms. The list specifies the pulses as three voltage points (points 0, 2, and 4), each with its corresponding
dwell points. The intervals are three zero-voltage points (points 1, 3, and 5) of equal time duration. The
count parameter causes the list to execute twice when started by a single trigger.
Transient list programming is supported through the front panel with the TRANSIENTS menu. Transient
lists can also be programmed through the remote digital interface using SCPI commands or the Sequoia
Virtual Panels GUI; refer to the Sequoia Series Programming Manual M447353-01, Tahoe Series
Programming Manual P/N M445374-01 or refer to AMETEK PPD website, www.programmablepower.com,

Figure 8-3: List Transients
To set up this type of transient list through the front panel, proceed as follows:
1. Navigate to the SETTINGS menu of the TRANSIENTS screen; refer to Figure 8-4 and Figure
8-5. Set the parameter values as follows:
Phase: A, B, or C
Time: sec
Volt(age): V
Freq(uency): Hz
Trig(ger): All
