GPIB Configuration

NOTE

Software Installation and Configuration 2

The following information assumes the GPIB interface card has been installed in your computer. If necessary, install the card as instructed by the documentation provided with the card.

The L4400 series instruments are available with an optional GPIB interface. The steps required to configure L4400 instruments for use over GPIB include:

•connecting the GPIB cables

•adding the instrument to the GPIB interface configuration (using Agilent Connection Expert)

•changing the instrument GPIB address (systems with multiple L4400 instruments)

•testing the IO path

Each L4400 series instrument is shipped from the factory with a default GPIB address of 9. Because instruments on the GPIB bus must have unique addresses, the L4400 instruments must be turned on one at a time, and the GPIB address changed before the next instrument is turned on and added to the configuration.

Connecting the GPIB Cables

GPIB cables can be connected in a “star” (all cables connect directly to the computer) or “linear” (instrument to instrument) configuration.

For systems with multiple L4400 series instruments, turn on only one L4400 instrument at this time. If there is another instrument on the bus at GPIB address 9 (i.e. 34980A), turn off that instrument until the address of the current L4400 instrument is changed.

Starting Agilent Connection Expert

Start Agilent Connection Expert by clicking the Agilent Control icon and selecting “Agilent Connection Expert” from the pop- up menu (Figure 2- 5).

The computer interfaces configured during installation of the Agilent IO libraries are displayed in the left column (Explorer pane) including the GPIB interface if a GPIB card is installed in your computer.
