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 VAC power unit are
included in the scope of supply.
A micro controller is responsible for the entire controlling, keypad query and display of
frequency and level on the LC display. The receiving frequency is indicated 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 precise level measuring. Up to 100 measuring device
settings can be stored as well.
A second micro controller allows you to store several 1000 measuring results on an SC card
or to read the SD card (up to 1GB) via USB.
For transmitter location the display has a bar graph. Additionally, a level-dependent bearing
sound facilitates directing an antenna without having to look at the display.
The audio unit with integrated speaker can process and render SAT NF signals, the TV NF
signals of B/G, D/K, I and M1 (JAPAN) and M/N standards, FM sound signals as well as
DVB-C, DVB-T and DVB-S(2). NICAM and AM sound rendering (standard L) is also
possible.
Remote power feed of 5...20 V/max. 600 mA (in 0.1 Volt increments), the superposition
of 22 kHz and the possibility of sending DiSEqC
TM
commands covers all currently known
requirements. With DVB-T a 5 V antenna feeding voltage can be received at the RF
connector. Also, the MZV 10 preamplifi er or similar can be fed remotely.
The integrated, transfl ective 5.7“ TFT colour display with a 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 displays the measurement results with very high
contrasts.
