3.2 IEEE-488 Interface
3.2.1 Pin Configuration
The 1855 instrument has an optional IEEE-488 interface as illustrated in Figure 3-2. Connection
is through the blue 24-pin connector labeled ‘IEEE-488 INTERFACE’ on the rear panel of the
1855 instrument. This interface can be used to connect a system containing a number of
instruments and a controller in which each meets IEEE Standard 488.2 (Standard Digital
Interface for Programmable Instrumentation).
