2.
On the Entry keypad, press
↑
or
↓
to scroll through the
mode parameters to obtain
LIST
and press Enter.
VOLT:M
LIST
3. Access the List menu (by pressing Shift List). The first
menu command is the list count. From the Entry keypad,
change the list count from the default (1) to 2.
COUNT 2
4. Access the List menu again and press
t
to access the
dwell time list. This specifies the "on" time for each
voltage point, which is effectively the output pulse width.
The first dwell point (0) appears in the display. From the
Entry keypad, enter .033 as the value for dwell point 0.
DWEL 0 033
5. On the Entry keypad, press Shift
s
Index to scroll to the
next dwell point and enter .067 as the value for point 1.
Note that dwell points 1, 3, and 5 specify the zero-voltage
time intervals, and are all set to zero
DWEL 1 .067
6. Repeat step 5 for the remaining dwell points. Enter .083
for point 2 and .150 for point 4. Enter .067 for points 3 and
5. When you finish, you will be at point 5.
DWEL 5 .067
7. Press
t
until you access the step command. Leave it at
the default mode (AUTO). This lets a single trigger run
your list for the specified count.
STEP AUTO
8. Press
s
until you access the voltage list. This specifies
the amplitude of each output point during its
corresponding dwell period. The first voltage list point (0)
appears in the display. From the Entry keypad, enter 160
as the value for voltage point 0.
VOLT 0 160
9. On the Entry keypad, press Shift
s
Index to scroll to the
next voltage point. Since V1 is zero, just press Enter to
accept the default. Note that voltage points 1, 3, and 5
are all zero.
VOLT 1 0
10. Repeat step 9 for the remaining voltage points. Enter 120
for point 2 and 80 for point 3. When you finish, you will be
at point 5 (which is set to 0 volts).
VOLT 5 0
11. Press Trigger Control and Enter to initiate the immediate
trigger.
INIT:IMMED
12. Press Shift Trigger Control. This sends the AC source an
immediate trigger signal to generate the voltage list.
Table 34 : Programming Transient Lists
Note: The AC source output returns to the immediate programmed values at
the completion of the list.
In three phase mode, the voltage lists are phase selectable. You can set up a
different voltage list for each phase. To do this, use Phase Select to first choose the
desired phase, as previously described in example 1 for setting the immediate output
voltage.
4.7 Trigger Delays and Phase Synchronization
The AC source trigger system also lets you program trigger delays as well as
synchronize output changes to a specific phase angle of the output waveform.
