Programming the Oscilloscope

When you attach an interface module to the rear of the HP 54645 A/D

Oscilloscope, it becomes programmable. That is, you can hook a

controller (such as a PC or workstation) to it, and write programs on

that controller to automate oscilloscope setup and data capture. Both

HP-IB (also known as GP-IB, IEEE-488) and RS-232-C interfaces are

available.

The following figure shows the basic structure of every program you

will write for the oscilloscope.

Initialize

To ensure consistent, repeatable performance, you need to start the

program, controller, and oscilloscope in a known state. Without

correct initialization, your program may run correctly in one instance

and not in another. This might be due to changes made in

configuration by previous program runs or from the front panel of the

oscilloscope.

• Program initialization defines and initializes variables, allocates

memory, or tests system configuration.

• Controller initialization ensures that the interface to the

oscilloscope (either HP-IB or RS-232) is properly set up and ready

for data transfer.

• Oscilloscope initialization sets the channel configuration and labels,

threshold voltages, trigger specification and mode, timebase, and

acquisition type.
