Controlling Instrument Basic From Remote; To Control Gpib From Instrument Basic; Pass Control - Agilent Technologies 4396B Gpib Programming Manual

Controlling Instrument BASIC from Remote

This chapter is for programmers who use both Instrument BASIC and an external controller
at the same time. This chapter shows how to pass control and how to use the PROGram
subsystem commands. The PROGram subsystem is part of the SCPI commands hierarchy. See
the
GPIB Command Reference
If your GPIB has only one controller (either an external computer or the Instrument BASIC),
skip this chapter.

To Control GPIB from Instrument BASIC

The analyzer must be the active controller of the GPIB (select code 7) when controlling the
device on the GPIB. Initially, the system controller is active. The active controller can pass
control to the analyzer (or other controllers, if there are others on the GPIB).

controller?
manual for more information on how to use SCPI commands.
Figure 7-1. Pass Control

The active controller determines which controller can manage the GPIB
(that is, have control). The GPIB can have only one active controller at a
time. If two or more controllers are on the same bus, control is passed
from one controller to another.

Resetting the GPIB (this operation can only be done by the system
controller), the returns control to the system controller.
