An instrument for measuring the voltage standing-wave ratio of a generator

Conclusions

The comparison results confirm the relatively high accuracy of measurement of the standing-wave ratio by means of the above instrument.

The instrument can also be used for matching the generator when its potput is insufficiently decoupled and there is a possibility of the results being distorted by the reaction of the adjustable plunger on the generator. For avoiding this reaction another hole should be made in the body of the plunger, and an absorbing sliding wedge placed in it. The protruding wedge lowers the standing-wave ratio of the instrument and decreases its effect on the generator. When the instrument is used for accurate measurements of the standing-wave ratio the absorber is pushed inside the plunger and produces hardly any effect on the operation of the instrument.
