Transient List point data entry method.
Transient list points are numbered sequentially from 0 through 99 and executed in this order.
Each list point or list entry has 9 parameters as shown in the table above. To enter list point
data, the keypad must be used. The shuttle knob is used to increment or decrement the list point
sequence number (#). The sequence number can only be increased to the next available empty
(new) list point.
To move to the next or previous parameter, use the UP () or DOWN () cursor keys
It is not necessary to use all list points, only as many needed to accomplish the desired output
sequence.
Setting Data Values
Data values can be set for each point in a list. If all data values in a specific list are going to be
the same value (e.g. the current limit parameter is set to the same value for the entire transient
program), only the first data value for that parameter has to be set. Setting only the first data
point will automatically repeat that value for all subsequent points in the transient list.
Setting Slew Rates
78
BUS Bus mode. The transient system is started by a bus command
or a group execute trigger (GET).
EX T External mode. The transient system is started by a user-
provided external TTL trigger signal on TRIGGER IN.
Indicates the transient system execution mode. A vailable modes are:
A UTO W hen triggered, the transient system will automatically
execute each list point sequentially without waiting for a
trigger between list points. This execution is paced by the
dwell time set for each data point.
ONCE W hen triggered, the transient system will execute the first list
point and wait for a new trigger once the dwell time expires.
This allows triggered execution of each step in the transient
list.
Step # V oltage set point
Step # V oltage slew rate in V /s
Step # Frequency set point
Step # Frequency slew rate in Hz/s
Step # Dwell time in seconds.
Range is 0.001 to 900000
Step # ON:
OFF:
The output trigger is available on the TRIG OUT on the rear
panel.
Step # W aveform selection. A vailable choices are Sinusoid, Square,
Clipped or any of the user provided waveforms in waveform
memory (-1Pi models only).
Step # Phase angle set point. (Not relevant for phase A
if clock mode is internal.)
Step # Current set point
DESCRIPTION
Generates an output trigger pulse at this list step.
No output trigger.
