A semiconductor diode modulator capable of measuring d-c currents down to 10/sup -10/ to 10/sup -11/ amp is described. Th is modulator utilizes one diode although a second is normally installed for balance purposes in high- sensitivity measurements. The modulator utilizes pulse techniques instead of sine waves which make possible the high sensitivity. The circuit details of the modulator and design criteria are discussed. (auth)
