Make Safe and Accurate Measurements with High-Voltage Probes

High-voltage measurements with a general-purpose oscilloscope aren't complex or esoteric, but they do call for tools and methods different from those used in everyday testing of logic and low-power analog circuits. High-voltage measurements are important for testing switching power supplies, motor controllers, power distribution systems, and more. This application note discusses the Tektronix TDS 220 Digital Real-Time oscilloscope and the companion P5100 High-Voltage Probe and explains their use in testing diode breakdown voltages on a Robicon Motor Drive control logic board.
