How it operates

The MSK 24 is designed as a universal portable test receiver for TV, SAT

and FM radio for both battery and mains operation. A built-in lead battery

with 2.8 Ah and a plug-in power unit for 230 V AC are included with the

receiver.

A microcontroller is responsible for controlling the unit, scanning the

keyboard and displaying frequency and level on the LC display.

Receiving frequencies are indicated in MHz. Levels are measured with a

peak or average value detector and indicated digitally in dBìV or dBmV.

Correction values are determined when levels are calibrated for the

MSK 24. They are stored in an EEPROM. Precise level measurements

can thus be made.

There is a bar display on the front display to help find transmitters. In

addition, there is an audio tracking signal to facilitate aligning of the

antenna as the display does not have to be observed.

The audio section with its built-in loudspeaker is capable of processing

and reproducing various audio frequency satellite signals, audio

frequency TV signals complying with the B/G, D/K, I, M1 (Japan) and M/N

standards, as well as FM audio. NICAM and AM audio reproduction

(L standard) is also possible.

All currently known requirements are covered thanks to an LNB supply

voltage of 10-20 V / max. 500 mA with steps of 0.1 V, the superimposition

of 22 kHz / 60Hz and the facility of sending DiSEqC or V-SEC

commands.

The built-in TFT colour screen allows pictures to be assessed locally.
