Thermo KeyTek PK1001D

The differential oscilloscope probes normally used for monitoring high voltage surges and transients are generally large and cumbersome (because they are designed for use to 40 kV), unduly sensitive to noise, and difficult to maintain in close compensation adjustment. KeyTek's Model PK 1001D is a relatively small, lightweight probe designed to provide accurate transmission of peak surge waves to 6 kV, with fronts from 10 ns to 1.2.
