Abstract : An electronic charge calibration circuit is described which applies two accurate, short-duration, linear charge-calibration steps to a multichannel cathode-ray tube type air blast recorder. The calibration steps are produced electronically and essentially have no inherent minimum time as is present in electro-mechanical relay systems. The calibration time per step for this system is about 3/4 millisecond. (Author)
