Hello All,
What is a Source Measure unit (SMU)?
What Is a Source Measure Unit (SMU)? - National Instruments
Yesterday I unpacked a shiny Keysight B2962A SMU.

This thing puts out constant DC voltage with an adjustable current limit. It puts out constant DC current with an adjustable voltage limit. It has adjustable output impedance. It puts out selectable AC voltage or current with adjustable current or voltage limits. It outputs 6 (not sure of the number) selectable output functions; sine, square, triangle…sawtooth and arbitrary user programed wave forms. It measures and records output voltages and currents. It is programmable to output I/V plots (tube plate curves) at least for signal tubes with B+ voltages less than 210 volts. Alternately it will also plot tube in circuit I/V plots, plots that look similar to plate curves however the shape and slope of the curve will be different as will the gain be different from the mu of the tube.
This instrument also reports to and can be controlled by a PC by way GPIB, Lan and LabVIEW software.
Does anyone use one of these or similar remote interface instruments on your bench.
Thanks DT
I posted this in the tube section because I got the instrument to test tubes.
