Introduction to Controlling an WDCA
One of the easiest ways to learn how to write programs to control the instru-
ment is to look at simple examples. In "Example Programs" on page 5-33,
you'll find several useful example programs. Although they are written using
the Microsoft Visual Basic language, you can easily convert them to the lan-
guage that you are using. The Agilent 86082A's GPIB address is configured at
the factory to a value of 23. You must set the output and input functions of
your programming language to send the commands to this address. Pressing
the green Preset key does not change the GPIB address.
To change the GPIB address
1 Press the front-panel System key.
2 Press the More System Functions.... softkey.
3 Press the Remote Setup.... softkey, and change the GPIB address.
Remote mode and front-panel lockout
Whenever the instrument is in Remote mode, the RMT message is displayed on
the instrument's screen and all keys are disabled except for the front-panel
LOCAL key. This key can be pressed by the user to restore front-panel control
of the instrument, even when the display is off.
You can specify a local lockout mode that deactivates the front-panel LOCAL
key. If the instrument is in local lockout mode, all the front-panel keys are dis-
abled.
Consult the documentation for your programming environment to determine
which commands are used to put an instrument in the remote and local lock-
out modes. These are not Agilent 86082A commands; they are GPIB interface
control level commands.
Synchronization Commands
The WDCA will not necessarily execute the commands in the order they are
received. That is, it will not necessarily wait until one command completes
before starting the next one. Two synchronization commands are provided,
*OPC (operation complete) and *WAI (wait), that allow you to tell the instru-
