With Sat/TV/FM signal meter MSK 33, detailed quality assessment of DVB-C, DVB-T and DVB-S signals may be carried out along with level measurements of analogue and digital TV and Sat reception signals. The unit is constructed in modular technology, so future function extensions by means of plug-in cards are easily possible.

The MSK 33 can be optionally supplied with power via the integrated lead accumu- lator of the integrated power supply unit (110…240 V~). A microcontroller is re- sponsible for controlling the unit and scanning the keyboard entries with the hard and softkeys as well representing the level and frequency on the integrated TFT display screen. The high definition display screen allows a precise picture as- sessment.

Four different detectors for peak, average, maximal and minimal values are avail- able for the level measurement of analogue and digital signals. Correction values are determined by the level calibration of the MSK 33 and stored in an EEPROM. This allows precise level measurements to be made with the MSK 33.

The MSK 33 is developed for the standards B/G, D/K, I, L, M, M Japan and Nicam. The video signal can be processed and reproduced in the colour standards PAL, SECAM and NTSC.

There is a bar display on the front display to help locate transmitters. In addition, a level-dependent acoustic tracking signal simplifies the alignment of an antenna without having to look at the screen.

The LNB supply voltage is 10 V…20 V for max. 500 mA in increments of 0.1 V. For control of the receiving system, the 22 kHz signal as well as the commands for DiSEqC 2.0, UFOµ-DiSEqC or V-SEC commands can be produced.

Level values, frequencies and plus the entire frequency spectrum can be printed out via the integrated dot-matrix printer.
