2657A-LIM-3 LO Interconnect Module establishes measurement commons (LO and sense LO) for a test system using multiple source-measure units (SMUs) that includes at least one Model 2657A High Power System SourceMeter Instrument.

2657A-LIM-3 creates a single-point interlock connection for SMUs connected to the interlock input terminals. When the interlock circuit is interrupted by an open interlock switch, the outputs of all SMUs will disable.
