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. The following figure shows a voltage
output generated from a list. The output shown represents three different AC voltage pulses (160 volts for
33 milliseconds, 120 volts for 83 milliseconds, and 80 volts for 150 milliseconds) separated by 67
millisecond, zero volt intervals.
Transient list programming is supported from the front panel and may be accessed by selecting the
TRANSIENTS entry in the MENU 1 screen. Transient lists can also be programmed over the bus. Refer
to the SCPI Programming Manual for more information about programming List transients and triggers
over the bus.
Figure 5-29: List Transients
The list specifies the pulses as three voltage points (point 0, 2, and 4), each with its corresponding dwell
point. The intervals are three zero-voltage points (point 1, 3, and 5) of equal intervals. The count
parameter causes the list to execute twice when started by a single trigger.
To set up this type of transient list, proceed as follows:
1.
Press the PROG key to bring up the PROGRAM 1 menu.
2.
Move the cursor to the VOLTAGE field and enter 0 Volt. Press ENTER to confirm your setting.
3.
Make sure you are in the HIGH voltage range as we will program a surge to 160 V rms. The low
range would only allow 150 V rms.
4.
Press the MENU key to bring up MENU 1.
5.
Move the cursor to the TRANSIENTS entry and press the ENTER key. You are now in the
TRANSIENTS menu.
6.
Move the cursor to the VOLT SURGE/SAG entry and press the ENTER key. You are now in the
VOLT SURGE/SAG SETUP menu.
7.
If you have a three-phase configuration and are in the three-phase mode, use the PHASE key to select
all three phases. (øABC will be displayed in the top right corner of the screen.)
8.
The START ø may be left at RANDOM as we are not interested in starting at a specific phase angle.
If a number is already present in this field, use the BACKSPACE (<-) key to clear it.
