OUTPUT

The Agilent BASIC language statement that addresses the power supply to talk and reads back data from the power supply is:

ENTER

The supply’s front panel ADDR annunciator is on when the supply is addressed to talk or to listen.

Reading the GP-IB Address

Before you can operate your power supply remotely, you need to know its GP-IB address. The address was displayed during the power on sequence described in Normal Self Test Indications, page 35. To see the address, press:

ADDR

A typical address display is shown in Figure 3-6:

Figure 3-6. Typical Address Display

The displayed response is the power supply’s GP-IB address. When sending a remote command, you append this address to the computer’s GP-IB interface select code (normally 7). For example, if the select code is 7 and the power supply’s GP-IB address is 5, the combination is 705.

Changing the GP-IB Address

NOTE

All examples in this discussion assume a GP-IB address of 5. It is recommended that you retain this

 

address to simplify programming.

 

 

Every device on the GP-IB must have an address. The supply’s address is factory set to decimal 5. Any address from 0 through 30 is a valid address. If you need to change the Agilent 662xA Supply’s address press:

ADDR

You can now enter a new address. For example, press:

1

4

ENTER

You have now changed the address from 5 to 14. If you want to change the address back to 5, repeat the above procedure but use 5 instead of 14 in the last step. Note that the address is stored in the power supply’s non-volatile memory and therefore will be retained through interruption of the ac line power.

Sending a Remote Command

To send the power supply a remote command, combine your computer’s output statement with the GP-IB interface select code, the GP-IB device address, and finally, the power supply command. For example, to set the output voltage of output channel 1 to 2 volts, send:
