HTRIGGER SCPI COMMAND SUBSYSTEM

This section applies only to units with the External User Interface
(Currently only available on Ethernet versions).

The HTRIGGER function allows the user to apply an External User
Interface input signal to initiate a sequence or a voltage or current ramp.
Once a hardware trigger is run, Arm goes to 0 (not armed); however, the
last loaded sequence remains in memory.
