4.3 GENERAL OPERATION WITH SYSTEM 55
SYSTEM 55 is an IBM Compatible, Windows based proprietary EMC susceptibility program
specially designed to integrate the CMX25 with other IFI equipment into an efficient and flexible
automated EMC Testing System for immunity testing. It is capable for IEC801-3 testing as well
as a real time leveled sweep that maintains a desired preset field level across a given frequency
range.
