The Micro Systems programmable C-Band Mini-Tester (Model 38-2 and -4) is a handheld battery powered unit that provides Go/No-Go testing for any C-Band transponders in the 5.4-5.9 GHz range including all variations of Micro Systems Radar Transponders. The Mini-Tester verifies proper transponder operation by interrogating a transponder installed and powered in a systems platform. Indicator LED’s verify the transmission of signals and the received reply. The Mini-Tester is programmable and uses the same USB programmer used to program the Micro Systems transponders which allows for quick frequency changes. The Model 38 Mini-Tester is capable of testing units more than 350 feet away and comes complete with battery charger and antenna.
