Special model for EGIS-Rotor™ positioner

The well-kown EGIS-Rotor has an analog input (AGC) for signal-strength dependent positioning optimization (Auto-Tracking).
This feature is essential for tracking stellites in inclined orbit positions.
Such satellites are inclined in higher amplitudes.
Therefore a fixed antenna would deliver a fluctuating signal quality over the time.
Only an additional information like the the already mentioned AGC-signal always guarantees the best available signal quality. The antenna will follow the satellites position automatically (Auto Tracking).
In the days of analog satellite-TV many satellite receivers were able to deliver such a signal strength dependent voltage - the so-called AGC output.
This valuable feature is lost with the new generation of digital satellite receivers.
We can now offer a special model of the SpectraBox SAT DX which has an additional signal strength dependent output.
Operating the SpectraBox in Zero-Scan mode (0MHz/DIV) the device works like a receiver tuned to a fixed frequency.
This mode generates an optimum AGC voltage for the EGIS-Rotor.
Together with the Auto Resume firmware this model is especially optimized for EGIS-Rotor applications.
This model is also available with the standard DX firmware on request.
