GR 874 VR “T” Shape
Voltmeter Rectifier – The 874-VR is used to monitor the voltage in a coaxial system. Similar to the VQ, the 874-VR has a 50-ohm resistor in series with the output-port center conductor. In combination with a signal source and properly calibrated indicator it can simulate a 50-ohm generator with known open-circuit voltage. It is used in this manner with the GR 1263-C in an oscillator amplitude-regulating system.
