Chapter 6, IBASIC Controller
Method #1. Program Development on an External BASIC Language Computer
Program Development Procedure
The Test Set has two GPIB buses, an internal GPIB at select code 8 and an
external GPIB at select code 7. The Test Set's built-in IBASIC controller uses the
internal GPIB 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 GPIB. For example, to
setup the Test Set's RF Generator use the OUTPUT command with the Test Set's
GPIB address. If the select code of the GPIB 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 GPIB 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 GPIB commands to 8XX (Test Set internal GPIB
bus) and downloading the program into the Test Set's IBASIC controller and
executing it.
