Weinschel VM-7

The Weinschel VM7 Attenuator and Signal Calibrator is a 30MHz receiver intended to be used in those applications where the precise measurement of RF power ratios is required over a wide dynamic range. One typical application of this single-channel device is the measurement of insertion loss by two-port RF microwave devices, such as filter, attenuators and switches.
