    Multimetter FSM 650 Ref. 5923 3.3.1.2.3.- SCR The FSM 650 is capable of controlling devices (LNB, multiswitches) compatible with the SCR protocol defined in the 50494:2006 standard. The basic purpose of this protocol is to divide the FI bandwidth (950MHz to 2150MHz) into user bands or “slots”. The number of wavelengths varies from one application to another, and the maximum is defined in the standard as 8.
