External Trigger Modes

When in external triggered mode, a burst or duty cycle mode can now be selected:

When in burst mode, the system burst will be started when a trigger event is received.

Subsequent trigger inputs will start a new burst sequence. The burst sequence will not be
restarted with subsequent triggers until the existing burst sequence is finished. The period
of the burst pulses are selected by setting the system period.

When in duty cycle mode, each incoming trigger will produce a single pulse on ea ch

active channel for each external input trigger signal for the set “N” number of on counts
but will ignore the set “M” number of off counts. The duration of complete cycles when in
this mode is controlled by the “Cycle Counts” parameter.

When the trigger mode is set to REARM, the external trigger input functions the same as

if a *ARM command was sent. This will re-arm all channel timers.

External Trigger Rate

This feature allows the unit to be externally triggered at rates up to 20MHz.

External Trigger Re-Arm

This feature allows you to select an external trigger mode that operates the same as issuing a
*ARM command. When the external trigger is set to this mode, you can now re -arm the channel
timers by inputting a trigger pulse to the external input.

Synchronous Update Mode

The channel timers (delays and widths) can be manually updated so that all changed values are
applied synchronously. Normally when any width or delay is changed, it is automatically applied.
When in synchronous update mode, all channel width and delays can be adjusted and then
updated all at once via a single command. This gives better control over parameters that need
to be implemented all at the same time. This option does not allow the user to delay the
amplitude changes to an output, only the timing. This feature needs to first be enabled in order
to take affect when the “Update” is carried out.
