Software defined transmitters
 Software Defined Transmitters are a new generation of transmitters allowing increased flexibility and reduced cost of ownership.
Built on the experience of the multimode capable MOD-ALL family of modulators, the MAGNUM Series uses one hardware for any analog and digital standard, and it may change its operating mode in the field. The MAGNUM series can load different modulation schemes, thus allowing a smooth transfer from analog to digital broadcasting or easy migration from one digital standard to another.
