Chapter 7, IBASIC Controller
Method #1. Program Development on an External BASIC Language Computer
Program Development Procedure
As discussed in
"Overview of the Test Set" in chapter 1
, the Test Set has two
HP-IB buses, an internal HP-IB at select code 8 and an external HP-IB at select
code 7. The Test Set’s built-in IBASIC controller uses the internal HP-IB to
communicate with the Test Set’s various instruments and devices. The process of
developing a program on an external BASIC language computer utilizes this
hardware feature to an advantage. First, develop the program directly on the
external BASIC language computer treating the Test Set as a device on the
external BASIC language computer’s HP-IB. For example, to setup the Test Set’s
RF Generator use the OUTPUT command with the Test Set’s HP-IB address. If
the select code of the HP-IB card in the external BASIC language computer is 7
and the address of the Test Set is 14 the address following the OUTPUT command
would be 714. When the command executes on the external BASIC language
computer the information on how the Test Set’s RF Generator is to be configured
is sent to the Test Set through its external HP-IB bus. After the program is fully
developed, making it run on the Test Set is simply a matter of changing the
address of all the HP-IB commands to 8XX (Test Set internal HP-IB bus) and
downloading the program into the Test Set’s IBASIC controller and executing it.
