The HF selector XDM-16 is a compact device for switching HF signals in the range of 0÷18GHz. The device combines in each of the sixteen channels two signals from receiving antennas of the HF/VHF bands and microwave bands, delivering them to the input of the connected broadband receiver. 

The HF selector is designed to broadband listening services, monitor of the frequency spectrum, reconnaissance and radio-electronic warfare.

In order to ensure continuity of impedance and constant load of distribution amplifiers, all not used outputs are terminated with broadband loads of 50 Ohm.

The HF selector is supervised by a locally and remotely controlled microprocessor system, equipped with modules for controlling the work of DP-DT coaxial switching relays.

The selector in its basic operating mode is remotely controlled (external control) via a computer network (LAN), using the TCP protocol, by a master unit (e.g. a reconnaissance system controller).

In the back-up mode, it is possible to manually control, with the use of a touch panel, displaying the status of inputs and outputs. The XDM-16 touchscreen presents the status of the switched lines continuously.
