TRIGger Subsystem
The instrument is unlike most SCPI instruments in that it is continuously taking readings
and when a reading starts is under the control of the scan engine and not the user. As a
result, the user should not attempt to control the instrument though the Trigger
subsystem. The commands below are listed only for the sake of completeness.
