		The Agilent N6700 MPS supports GPIB, LAN, and USB interfaces. All
		three interfaces are live at power-on. The front panel IO indicator
		comes on whenever there is activity on the remote interfaces.

GPIB Interface

For detailed information about GPIB interface connections, refer to the Agilent

NOTE

Technologies USB/LAN/GPIB Interfaces Connectivity Guide, located on the

Automation-Ready CD that is shipped with your product.

The following steps will help you quickly get started connecting your

instrument to the General Purpose Interface Bus (GPIB). The

following figure illustrates a typical GPIB interface system.

1If you have not already done so, install the Agilent IO Libraries Suite from the Automation-Ready CD that is shipped with your product.

2If you do not have a GPIB interface card installed on your computer, turn off your computer and install the GPIB card.

3Connect your instrument to the GPIB interface card using a GPIB interface cable.

4Use the Connection Expert utility of the Agilent IO Libraries Suite to configure the installed GPIB interface card’s parameters.

5The power system is shipped with its GPIB address set to 5. Use the front panel menu if you need to change the GPIB address.

a Press the Menu key, then use the navigation keys to select System\IO\GPIB.

b Use the numeric keys to enter a new value. Valid addresses are from 0 to 30. Press the Enter key to enter the value. Press the Meter key to exit the menu.

6You can now use Interactive IO within the Connection Expert to communicate with your instrument, or you can program your instrument using the various programming environments.
