Mission Name: STP P78-2The Transient Pulse Monitor (TPM) was an engineering experiment which provided data on the electromagnetic pulse environment on the spacecraft. The experiment consisted of an electronic processor and four sensors which were built into the wiring harness. Two of the sensors were current probes which provided voltage signals to the electronic processor with sensitivities of 1 mV/mA. One of these probes measured current fluctuations in the solar array power line, and the other measured current fluctuations in the ground line of the main power system. The other two sensors were long wire antennas mounted outside the shields of the main cable bundles. The two antennas ran parallel to each other and differed only in the magnitude of their terminal impedances. The electronic processor had commandable sensitivities and continuously monitored electrical signals from each of the four sensors simultaneously. The processor provided the following information for each sensor once per second: total pulse count, positive voltage-time integral, negative voltage-time integral, positive peak voltage amplitude, and negative peak voltage amplitude.
