Recent developments in communications measuring instruments

Rapid expansion in radio communication systems has created a corresponding demand for both new and improved forms of instrumentation. The paper gives a brief summary of the present position as seen through the eyes of the instrument designer. It is shown how needs are being met by: (1) improving existing design by the process of continuous development; (2) developing and exploiting new measuring techniques; (3) producing test sets to fulfil certain specific functions. Examples are given by way of illustration and reference is made to some of the technical and economic factors affecting the instrument manufacturer.
