A computer controlled 300 kV pulse generator

A high-voltage pulse generator used primarily for calibrating precision high-voltage dividers has been redesigned and rebuilt for state-of-the-art operation. It now has the capability to run a divider calibration, compare the results with historical data for the divider, and then print a calibration certificate, all under computer control. Thirteen component instruments are controlled through three IEEE 488 buses. A voice synthesizer is used to inform the operator of the progress of the calibration. Measurement precision is in the 0.1% range. A heat exchanger is used to control the temperature of the oil bath to allow calibration of dividers between 13°C and 21°C. Positive or negative pulse polarity can be selected, and pulse magnitude is settable from less than 10 kV to greater than 300 kV
