Features
Ease Of Use
The 1257 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 1257 is ready to use as soon as the custom
drawer has been inserted.
•
Flexible Controller Interface.
The controller (host
computer) may communicate with the 1257 using either
IEEE-488 (GPIB) or RS-232 interfaces. This allows an
external computer to automate the operation of the 1257.
•
Front-Panel Controls.
The front-panel controls provide an
intuitive user interface for manually controlling the drawer
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 1257 supports the
Standard Commands for Programmable Instruments (SCPI)
Language. This command set is used in other switching
platforms such as the 1257 GPIB and 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 1257, see

6, SCPI COMMAND REFERENCE
