The oscillation of these electric currents create electromagnetic radiation in the RF range. These radio emissions are correlated to the video image being displayed, so, in theory, they can be used to recover the displayed image. In a CRT, the image is generated by an electron beam that sweeps back and forth across the screen.

The design was originally intended to be a relatively simple upgrade to the F-84 Thunderjet to make it more competitive with the F-86 Sabre, differing largely in the use of a swept-wing and tail.
An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF (radio frequency) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT). Incorporating a switch into a switch matrix system enables you to route signals ...
