Howard Dicken at DM Data Inc. has written a fantastic review of the Syscomp CTR-101 Curve Tracer. Executive summary follows:
This tester is recommended either as the basic equipment or as a back-up to other higher priced units in the industry. This Syscomp unit will perform 70% to 80% of the normal lab requirements for semiconductor and electronic failure analysis. In addition this unit will provide several measurement capabilities not available on some Tektronix scopes.
