DCBT-002RJ is a test jig for X-band and C-band radar transponders. It powers the transponder, displays its 28V supply current, selects the pulse code (CODE1–CODE5), and monitors the pulse, PRF, and RSSI outputs. A built-in pulse generator produces single or double interrogation pulses with adjustable pulse width, delay, and PRF. The jig operates standalone from the front panel or under PC control via RS-232, including code, pulse, PRF, and radar simulation.
