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 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 and I, FM sound signals as well as DVB-C, DVB-T and DVB-S(2). NICA
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 DiSEqCTM 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 preamplifier or similar preamplifiers can be fed remotely.
The integrated, transflective 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 LC displayshows the measurement results with very high contrasts.

DISEQCTM (DIGITAL SATELLITE EQUIPMENT CONTROL)
The DiSEqCTM system is used to control systems with extended
control functions. DiSEqCTM uses a serial, bi-directional transmission
process with a master and one or multiple slaves. The data bits
are generated with pulse width modulation of the already existent
22 kHz carrier and are superimposed with 600 mVSS of the LNB
remote feeding voltage. The digital code words are composed
of 8 data bits and one additional parity bit for the recognition of
transmission errors. Multiple code words form one DiSEqCTM
command. Code words are entered in hex code:

COMMAND OVERVIEW FOR DISEQCTM
If a DiSEqCTM matrix is activated via DiSEqCTM command, it
must first be ensured that the analogue LNB control voltage
is set to the correct Satellite frequency plane. I.e. if a vertical
satellite frequency plane is required, it is essential to set
the analogue LNB control voltage to 14 V. Then the correct
DiSEqCTM command can be selected and sent.

MAINTENANCE
The device maintenance is basically limited to outside cleaning.
DEVICE CALIBRATION
The caliber interval depends on the use and load and should be between one and two years. Calibration
can be done by Kathrein customer service. For address see next page.
OUTSIDE CLEANING
For outside cleaning a soft cloth, non-linting duster or paint brush is recommended. For strong
contamination spirit or mild soapsuds can be used as well. Never use any dissolvers like nitro-cellulose
combination thinner, acetone, etc., as these may damage the plastic parts and labels.
INSIDE CLEANING
Caution!
Since inside cleaning requires opening the device, such activity must be done by authorized personnel
only. The device should be dust-cleaned inside in regular intervals, app. every one to two years, to
ensure optimum ventilation. Cleaning intervals are based on the daily operating time and the dust volume
in operating rooms. For inside cleaning remove the back wall or the control part. Dust deposits can
be removed using a brush or grease-free compressed air.
FUNCTIONAL TEST
We recommend to check the specified required data in appropriate time intervals. For data and tolerances
please see the Technical Specification.
REQUIRED MEASUREMENT TOOLS
- TV/SAT signal generator to check level accuracy and analogue measurements and demodulations.
- DVB signal generator to check level accuracy and digital measurements and demodulations.

TECHNICAL APPENDIX
SIGNAL-TO-NOISE RATIO
To determine the carrier-to-noise-ratio (C/N) for analogue
transponders, the following values must be known:
• Ambient noise level (adjust parabolic antenna so that no
satellite signal is received)
• max. reception signal
• Bandwidth correction
The following formula applies:
C/N = reception signal level - ambient noise level - bandwidth correction
(MSK 125 measurement bandwidth) 6 MHz
Bandwidth correction value = 10 log ––––––––––––––––––––––––––––––––––
RF bandwidth reception signal
Bandwidth correction value = 6.37 dB for 26 MHz bandwidth (Astra)
Bandwidth correction value = 7.78 dB for 36 MHz (Eutelsat, Intelsat,
Kopernikus)
Example

Note
For exact C/N determination it is essential that the RF bandwidth
of the reception signal is considered.

CALCULATION OF SAT IF FREQUENCY USING THE MSK 125
This is done as follows:
IF = reception frequency - oscillation frequency
The oscillation frequency is made up as follows:
9750 MHz oscillator frequency is used for a reception frequency between 10700 MHz and 11700 MHz.
10600 MHz is used for a reception frequency between 11700 MHz and 12750 MHz.
Hence the values for ARD - Das Erste are:
IF = reception frequency - oscillation frequency
IF = 11836 MHz - 10600 MHz
IF = 1236 MHz
