NetScan User’s Manual
In order for an acquisition to take place, the unit must have a trigger event and can be assigned a Stop Event.
This allows different stimuli to begin and end an acquisition.
Note:
If the trigger start event is level or alarm, at least one pre-trigger scan must be programmed to
initiate scanning in order for the NetScan to recognize the event.
External TTL (High or Low Level)
Start and/or Stop Event. When External TTL Level is specified as a trigger source (T6 or T7), a TTL level
signal on the external trigger connector (rear panel BNC) will generate a trigger. The external trigger is level
sensitive, and triggering on the high level or low level can be specified.
Selected Temperature Channel (High or Low Level)
Start and/or Stop Event. When a selected channel is specified, data collection starts when the level for the
selected channel has been crossed (either high level or low level) as the user defined with the
L
command.
@ character
Start and/or Stop Event. When @ is selected as the trigger source, the command trigger (“@”) generates a
trigger when the Trigger Source is set for a command trigger (T1).
Alarm (on or off)
Start and/or Stop Event. When alarm is selected as a trigger source, the acquisition will start or stop when any
channel goes into or out of an alarm condition.
Absolute time
Start and/or Stop Event. When absolute time is specified, data collection starts when the real time clock time of
day equals the programmed time.
Count (post-trigger)
Start and/or Stop Even. When count is selected as the Stop Event, scans are collected until the specified number
of post-trigger scans (specified by the Y command) have been collected, at which time the post-trigger
Acquisition will stop and the post-stop Acquisition will begin, if configured.
