Keysight E1458A Register Information

Programming Example

The example in this section demonstrates how to program the module at the
register level. The programs follow the execution and timing models covered in
the previous section. The examples in this section include:

System Configuration

The following example programs were developed with the module at logical
address 144. The C language programs were developed on an Keysight V382
using ANSI C programming language and SICL (Standard Instrument Control
Library).
