Abstract :
A supervising instrument designed to measure the operating states of a high-power, medium-wave AM radio transmitter and its peripheral devices is described. The instrument can be used to measure the load impedance, output power, and efficiency of the final stage amplifier of the medium wave AM radio transmitter and can be used as a data logging and data analyzing instrument when the GP-1 B digital and analog interfaces are attached to the devices
