Gunn Oscillator Test Jig

MRA – 6 Z is an electronic distance measuring instrument with the accuracy of a few centimeters and a range performance of up to seventy kilometers. The development drew heavily from the air interface of its predecessor, MRA 6 which was first sold thirty years ago. The design now incorporates modern signal processing techniques including the de-modulation of the receive signal in a field programmable gata-ray. The work was done in collaboration with and for Tellumat. Tellumat have a history in distance measuring stretching right back to Plessey and Instrumentation Manufacturers of South Africa. The Tellurometer is a Trevor Wadley invention, he worked for the C.S.I.R.
