This section describes how to set or check the interface necessary to use the Agilent
4294A's GPIB (General Purpose Interface Bus). For more information on automatic

Switching between the System Controller Mode and Addressable-only
Mode
When you use the Agilent 4294A in an GPIB system, you have to specify whether to use it
as the system controller (system controller mode) or in the state where addressing is always
made from other devices (addressable-only mode). Follow these steps to switch between
the system controller mode and the addressable-only mode.
Step 1. Press the
[Local] key to display the Local menu.
Step 2. Select the system controller mode or addressable-only mode with one of the following
keys.
NOTE There should only be one system controller on a GPIB system. If there is another system
controller, set this instrument to the addressable-only mode. If you try to set the Agilent
4294A as the system controller using the above key while there is another system
controller, the “CAUTION: CAN'T CHANGE - ANOTHOR CONROLLER ON BUS”
error message is displayed.
To pass the GPIB control from the controller to this instrument, set this instrument to the
addressable-only mode in advance.
Setting/Checking the GPIB address
