CONTROLLER
The CONTROLLER command is used to configure the Analyzer488 to operate as
a High Level System Controller (CONTROLLER ON) or a Low Level System
Controller (CONTROLLER OFF). High Level Controller commands may only be
used when the Analyzer488 is in the High Level Controller Mode. Low Level
Controller commands may only be used when the Analyzer488 is in the Low Level
Controller Mode.
Issuing a CONTROLLER OFF command unasserts all bus management and data
lines. Issuing a CONTROLLER ON command pulses the IFC bus management line.
The query option, CONTROLLER?, returns the operational mode of the
Analyzer488.
