You can stir between the set values under dynamic trigger mode or
generate pulse under dynamic pulse mode.
⚫
Timing trigger: when the timing trigger is valid, the load will automatically
trigger an operation at intervals.
⚫
Bus trigger: when the bus trigger is valid, after the load receives a trigger
command (5AH) , the load will trigger an operation.
⚫
Trigger holding: when trigger holding is valid, only when the load receives
trigger command (9DH), the load will trigger an operation.

3.10 List operation
LIST mode provides an accurate, fast and low-cost way to complete any
complicated current change mode, which enables synchronization of internal or
external signals in multiple quasi-bit load precision tests.
When different trigger sources are selected, the LIST function will form a variety
of complex sequences by editing step value, pulse width and slope of each step
to meet complicated test requirements. LIST parameters comprise designation
of input list file, input step count (2-84 steps at maximum), step time (0.00005s
– 3600s) as well as setting value and slope of each step. The list file can be
stored in non-volatile RAM available for a quick output in case of usage. The
user can edit 7 groups of list files at maximum.
If the load operation mode is at List operation, the load will start List operation
when it receives a trigger signal and will stop when it complete or when it
receives another trigger signal.
