TSP #263 - Lakeshore M81 Synchronous Source Measure System (SSM) Review, Teardown & Experiments
In this episode Shahriar reviews the newly released Lakeshore M81 Synchronous Source Measure System. This unique product combines three key metrology techniques into one: source/measure capability, high-dynamic range remote-heads and lock-in capability while maintaining both DC and AC modes. In my view, this is an entirely new instrumentation category:
