General Information 5 General Information This user manual has been compiled for persons with some electrical engineering ability and knowledge. Us ers who have already operated similar measuring instruments can obtain the necessary commands for each operating step from the overview.
Functionality The MSK 25 has been conceived as a portable test receiver for TV, SAT and FM radio measurements, as well as for DVB-C, DVB-S and DVB-T in both, battery operation and mains operati on. The built-in lead battery (3.4 Ah) and a wall power supply with a built-in charger, suitable for 230 VAC, are included in delivery.
