Transmission Line Trainer
Product Code : JA-CT-1504
The transmission line trainer uses four 25 m coaxial cables, 100 m in all, to measure line characteristics, attenuation, input impedance, the phase between current and voltage, frequency response, stationary waves, phase shift along the line, fault location and pulse behaviour. A built-in sine/square signal generator covers 40 kHz to 4 MHz in two bands, and two potentiometers match the line impedance (SKU JA-CT-1504).
