17.9 Trigger
Trigger commands use several suffixes.
LEVel<n>, Noise<m>
The suffix indicates the analog channel, for which the command takes effect. C1 has
suffix 1, C2 has suffix 2, and so on.
Event<ev>
The suffix indicates the sequence step, for which the command takes effect when you
trigger on a sequence. If you trigger on a single event, the suffix = 1 and can be omit-
ted.
●
1 = A-trigger
●
2 = B-trigger
●
3 = R-trigger (reset event)
Asynchronous commands
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.
