Sub-nanosecond measurements of high-current and high-voltage pulses

We present a measurement tool encompassing four different types of sensors: a B-dot, a D-dot, a capacitive voltage divider, and a low-inductance current-view resistor. The tool can measure high-voltage, high-current pulses with rise times <150 ps. A calibration procedure for the device using a commercial pulse generator is demonstrated. Measurements of pulses with <150 ps rise time generated by a spiral generator with sharpening spark gaps are also presented.
