Summary

The REBLE610 features an accurate hardware design, absence of internal cabling and full modularity. The unit is composed by a basic chassis with 4 extractable boards which makes maintenance and critical operations, like frequency modification, easy and efficient. The modular approach has brought to the development of the digital processing module (containing modulator, demodulator and data interface) and the RF module (containing Transmitter, Receiver and channel filters). From an RF point of view, the new transmission circuitry is able to guarantee around 1 Watt with every modulation scheme, introducing, in addition, wideband precorrection (up to 1GHz depending on frequency band).

Description

The device suffers from an unauthenticated device configuration and client-side hidden functionality disclosure.
