7 FUNCTIONALITY The MSK 125 is a mobile multi-purpose measuring device intended for analogue TV and satellite, FM radio and for DVB-C, DVB-S(2) and DVB-T for battery and mains operation. The integrated 6.5 Ah lithium-ion battery and a rechargeable 230 V AC power unit are included in the scope of supply. A microcontroller provides all control functions, keypad polling and display of frequencies and levels on the LCD display. The reception frequency is displayed in MHz. The level is measured with a peak and mean value detector and displayed digitally in dbμv or dbmv. Correction values are determined during the MSK 125 level calibration and stored in an EEPROM. This ensures accurate level measurement. Up to 100 measuring device settings can also be stored. A second microcontroller allows you to store several thousand measurement results on an SD card or to read the SD card (up to 1GB) via USB. The display has a bar graph for transmitter location. Additionally, a level-dependent DF tone makes it possible to align an antenna without having to observe the display. The audio unit with integrated speaker can process and render SAT NF signals, the TV-NF signals of B/G, D/K and I, FM sound signals as well as DVB-C, DVB-T and DVB-S(2). NICAM and AM sound rendering (standard L) is also possible. The remote feed voltage of V/max. 600 ma (in 0.1 Volt steps), the superposition of 22 khz and the ability to transmit DiSEqC TM commands covers all currently known requirements. With DVB-T a 5 V antenna feed voltage can be received at the at the RF socket. The MZV 10 preamplifi er or similar preamplifi ers can also be fed remotely. The built-in transflective 5.7" TFT colour display with its resolution of 640 x 480 pixels allows for picture evaluation of analogue and digital TV and SAT signals in the dark as well as in sunlight. A large black and white LCD display shows the measurement results with very high contrasts. 7
