Getting Started

Instrument Definition

Each Keysight E1458A Digital I/O Module installed in an Keysight mainframe is
treated as an independent instrument, having a unique secondary GPIB address.
Each instrument is also assigned a dedicated error queue, input and output
buffers, status registers and, if applicable, dedicated mainframe memory space
for readings or data. Multiple digital I/O modules cannot be combined into a
single instrument.

Downloading the SCPI Drivers

The digital I/O driver allows the Keysight E1458A module to operate with an
Keysight E1405B or E1406 Command Module using the Standard Commands for
Programmable Instruments (SCPI) command language. The driver name for the
digital I/O module is "DIG_IO".
The procedure for downloading the drivers is contained in the Downloading SCPI
Device Drivers Installation Note supplied with the module. The C-Size VXIbus
Systems Configuration Guide also contain the installation procedure.
Programming the Digital I/O Module
To program the digital I/O module using SCPI, you must select the controller
language, interface address, and SCPI commands. Guidelines for SCPI command
selection for the digital I/O module are covered in this manual. See the C-Size
VXIbus Systems Configuration Guide for detailed interface addressing and
controller language information.
SCPI Command Format Used in this Manual
SCPI commands can be used in either long or short form. A long form example is:
The same command, without the lowercase letters, is the short form. For
example:

This discussion applies only to SCPI (Standard Commands for
Programmable Instruments) programming. See "Register
