Small Instrumentation Modules

SIM—Small Instrumentation Models—is a compact test and measurement platform for a wide range of applications. Unlike other modular systems, SIM offers complete front-panel as well as remote operation, allowing you to choose between manual and computer control. Up to eight instruments share the same mainframe which provides power, clock synchronization, communications, and Model status. For additional versatility, you can cascade mainframes or other RS-232 instruments, and even operate Models outside the mainframe.

With SIM, you configure precision measurement and control systems, achieving the exact functionality you need while avoiding the cost of unnecessary features.
