The RI 3101 Butler matrix controls the direction of your antenna beam, using spatial filtering, creating directional signal transmission or reception. Beam switching (steering the beam) is achieved by altering the input power port, 1-8. Typically a switch matrix is applied in front of the Butler matrix to control the power input.
EMScanner is a self-contained very-near-field scanning device which connects to a spectrum analyzer or a desk top PC running a copy of EMScanner Software. The EMScanner system operates from 150 kHz to 8 GHz and delivers repeatable and reliable results that pinpoint the cause of a design failure in seconds.
