Using HP-IB

Overview of the Test Set

The Test Set combines numerous separate test instruments and an

IBASIC controller into one package. All of the Test Set’s functions can

be automatically controlled through application programs running on

the built-in IBASIC controller or on an external controller connected

through HP-IB.

Developing programs for the Test Set is simplified if the programmer

has a basic understanding of how the Test Set operates. An overview of

the Test Set’s operation is best presented in terms of how information

flows through the unit. The simplified block diagrams shown in Figure

1-1 on page 28 and Figure 1-2 on page 29 depict how instrument

control information and measurement result information are routed

among the Test Set’s instruments, instrument control hardware,

built-in IBASIC controller, and other components.

The Test Set has two operating modes: Manual Control mode and

Automatic Control mode. In Manual Control mode the Test Set’s

operation is controlled through the front panel keypad/rotary knob.

There are two Automatic Control modes: Internal and External. In

Internal Automatic Control mode the Test Set’s operation is controlled

by an application program running on the built-in IBASIC controller. In

External Automatic Control mode the Test Set’s operation is controlled

by an external controller connected to the Test Set through the HP-IB

interface.
