Ease Of Use
The 1256 Switching System has many design features to make it
easy and convenient to use:
•
Fast Setup.
There are no configuration jumpers or switches
to be set. The 1256 is ready to use as soon as the plug-ins
have been inserted.
•
Flexible Controller Interface.
The controller (host
computer) may communicate with the 1256 using either
IEEE-488 (GPIB) or RS-232 interfaces. This allows an
external computer to automate the operation of the 1256.
•
Front-Panel Controls.
The front-panel controls provide an
intuitive user interface for manually controlling the plug-ins
and setting user preferences. The front-panel controls
provide access to all interface parameters, such as GPIB
address and RS-232 baud rates. These controls are often
helpful during system setup.
•
Command Set Commonality.
The 1256 supports the
Standard Commands for Programmable Instruments (SCPI)
Language. This command set is used in other switching
platforms such as 1260-Series VXI. For an introduction to
the SCPI command set and its usage, see
Chapter 5, SCPI
COMMAND BASICS
. For a complete description of all SCPI
commands for the 1256, see
