Simplify AC Differential Conductance Measurements

If you're characterizing non-linear devices or advanced materials, you know the tradeoff: DC techniques are straightforward but introduce 1/f noise and require time-consuming source-reversal and averaging. AC/lock-in methods solve those problems but demand multiple instruments, careful synchronization, and more setup time. This note walks through both approaches in detail and introduces the Lake Shore M81-SSM — a fully integrated source measure platform that delivers synchronized DC and AC lock-in measurements from a single system.
