The present invention relates to the improvement of a standing wave ratio device that detects the speed ratio between the traveling wave and the reflected wave launched from a transmitter, and its purpose is to eliminate troublesome calculation procedures or scales and conversion tables. The purpose is to provide the market with a measuring device that can directly read the speed ratio and the "loss" between cables without having to perform reading operations. Next, to describe the detailed structure and operation and effect of the attached drawing, the meter 1 that detects the traveling wave launched from the transmitter and the meter 2 that detects the reflected wave are placed in opposing positions, respectively. The hands 3 and 4 of the meters 1 and 2 are bent in a U-shape and exposed above the dial 5.
There is a grip 1 on which curved scales 6 and 7 are arranged corresponding to the respective hands 3 and 4, and a long hole 9 is provided in the center of a transparent cover 8 and a cursor 10 is arranged thereon.
1 (the cursor 10 rotates around the center of the grip and can move up and down integrally with the grip) and curved scales 6 on both sides of the upper surface of the dial 5, Between 7

値を検出し而うしてThe numerical value calculated by [Formula] can be directly read by aligning the cursor 10 (connecting the detected value of the traveling wave and the detected value of the reflected wave at the measurement point with the cursor 10).The scale marks 12, 13, 14 (20W
200W, 80W, and 200W), and by aligning the cursor 10 with the scales 15 and 16 that change the standing wave ratio between the cables in the vertical direction using the same procedure, the "loss" is measured. ” can be directly read scale 1
7 is a new feature. Conventionally, when determining the speed ratio of the traveling wave launched from a transmitter and the reflected wave, each value is detected in advance using a standing wave ratio measuring device.

その計測が極めて敏速に行へるわけである。It is common practice to find the value by calculating it from [Formula] or by aligning it with a conversion table and scale prepared in advance, but there are drawbacks such as not being able to read directly when detecting traveling waves or reflected waves. With the advent of the measuring instrument of the present invention, these drawbacks have been completely eliminated. Namely, the traveling wave emitted from the transmitter is detected by the meter 6, the reflected wave is detected by the meter 7, and the cursor 1 is detected via the grip 11.
By rotating 0 or moving up and down and connecting the two points with a straight line, it can be easily read directly on scales 12, 13, and 14, and the "loss" of the standing wave ratio between the cables can also be read on scales 15 and 16. By connecting the two points above with the cursor 10, the scale 17 can be directly read, so the measurement can be carried out extremely quickly.
