Configuring the Remote Interface

This section gives a brief description on configuring the remote interface. For further information on using the power meter remotely, refer to the HP EPM-441A/442A Programming Guide.

HP-IB Address

Each device on the HP-IB (IEEE-488) interface must have a unique address. You can set the power meter’s address to any value between 0 and 30. The address is set to 13 when the power meter is shipped from the factory.

The address is stored in non-volatile memory, and does not change when the power is switched off, or after a remote interface reset.

Your HP-IB bus controller has its own address. Avoid using the bus controller’s address for any instrument on the interface bus. Hewlett-Packard controllers generally use address 21.

To set the HP-IB address from the front panel:

1. Press

System

, HP-IB . The current setting of the HP-IB address

Use or to modify the digit on which the cursor is currently positioned.

Use or to move to other digits.

3.To confirm your choice press Enter .

To set the HP-IB address from the remote interface use the:

SYSTem:COMMunicate:GPIB:ADDRess command.
