EFR - telegram generator

EFR - telegram generator

The EFR-telegram generator EFRG1 (fig. 1) is an easy to handle, compact equipment which allows the generation of high frequency FSK-modulated signals conform to the EFR-telegram specifications as well as the generation of lower frequencies, normally used as intermediate frequency inside of ripple control receivers.

By the connection of a corresponding transmitting antenna, the generated signals can be broadcasted in order to generate a well defined field-strength inside of a specified area. The EFRG1 is able to be completely remote-controlled by the connected PC or it can work in its “stand-alone” operation mode.
