Agilent Technologies 6811B, 6813B Controller Connections, GPIB Connector, 6. FLT/INH Examples

2 - Installation

In example B, the FLT output of one unit is connected to the INH input of another unit. A fault condition in one of the units will disable all of them without intervention either by the controller or external circuitry. The controller can be made aware of the fault via a service request (SRQ) generated by the Questionable Status summary bit.

Controller Connections

The ac source connects to a controller either through a GPIB or an RS-232 connector.

GPIB Connector

Each ac source has its own GPIB bus address. AC sources may be connected to the bus in series configuration, star configuration, or a combination of the two. You may connect from 1 to 15 ac sources to a controller GPIB interface.

NOTE: The ac source is shipped from the factory with its GPIB address set to 5. This address can be changed as described in Chapter 4 of this guide.
