External Gate Signal Threshold
For external source
addition to the gate signal polarity. This is done using the command:
INPut[1]:LEVel[:ABSolute]{<volts>|MINimum|MAXimum|DEFault}
INPut[1]:LEVel[:ABSolute]?[{MINimum|MAXimum|DEFault}]
The specified edge (polarity) of the gate signal crossing the threshold opens the
gate. The opposite edge (polarity) of the signal crossing the threshold closes the
gate. (More information on the INPut subsystem can be found in
