General Information General Information This user manual has been compiled for persons with some electrical engineering ability and knowledge. Users who have already operated similar measuring instruments can obtain the necessary commands for each operating step from the overview. In addition, the following examples will help you understand each operating step.
Functionality The MSK 25 has been conceived as a portable test receiver for TV, SAT and FM radio measurements, as well as for DVB-C, DVB-S and DVB-T in both, battery operation and mains operation. The built-in lead battery (3.4 Ah) and a wall power supply with a built-in charger, suitable for 230 VAC, are included in delivery. Controlling and scanning of the console and the display of frequency and level on the LCD are carried out by a microcontroller. The receiving frequency is indicated in MHz.

Connections Connections RF Input Socket The received signal of the antenna or of the cable network is fed in here (BNC coaxial socket). The remote feeding voltage (for LNB) is adjustable from 5 VDC to 20 VDC and can be switched off. When the LNB voltage is switched on, the LED next to the RF input socket flashes. Make sure that there are • no voltage level over 120 dBµV, • no positive DC voltage over 22 VDC, • no negative DC voltage and • no AC voltage adjacent to the RF input socket.
Commissioning Commissioning Switching-Up Software V2.0 SN: 000222 ACCU • Connect the instrument to the mains with the wall power supply. • Turn the on/off switch to the right. • Adjust the desired volume. The LC display will then indicate the particular software version for appr. 1 second. [−−−−−] Thereafter the LC display will indicate the loading capacity of the battery for appr. 3 seconds. One segment comes up to appr. 20% of the overall capacity (3.4 Ah).

Factory Setting on Delivery Parameter POWER ON LNB DC LEVEL Low Level Mute Setting TV OFF dBµV ON Setup Menu Setting Setup Menu Call-Up Press [2ndF] and [SETUP]. The particular mode (TV, SAT, FM) is selected and taken-over by pressing either [1], [2] or [3]. The current setting is retained by pressing [ENTER.] POWER ON 1=TV 2=SAT 3=FM 1.
Commissioning Mains Operation and Battery Operation The MSK 25 may either be mains operated or be battery operated (battery built-in). Mains Operation Only the wall power supply delivered may be used for power supply. Connect it to the voltage supply socket on the right hand side of the instrument. Sustained continuous operation (incl. MPEG option) is possible in case of an LNB power consumption of no more than max. 300 mA.
SAT measurement SAT measurement Standard Change-Over In SAT mode, the MSK 25 receives • analogue signals and • DVB-S signals.
SAT measurement Frequency Display and Frequency Entry To measure the level of a received signal, you must first enter the frequency required. The LC display indicates the frequency and the level measured. Frequency entry is possible from 920 MHz to 2150 MHz in 100 kHz steps. ☞ SAT Menu Frequency Entry [SAT/TV] Changing over to SAT reception À [0] to [9] Entering frequency [+] [-] Varying frequency in 100 kHz steps [ENTER] Confirming your entry FR:1288.0MHz LEV: 66.
SAT measurement SAT Analogue Level Measurement Once you have entered a frequency, the level is measured automatically and displayed either in dBµV or dBmV (depending on the basic configuration) on the LC display. The input level can be measured in the range of 30 dBµV to 120 dBµV (-30 dBmV to 60 dBmV). LC display: FR:1508.0MHz LEV: 86.5dBuV SAT A │ • Frequency: 1508 MHz • Mode: SAT • Level measured: 86.5 dBµV A Level Overflow and Level Underflow FR:1508.0MHz LEV: __._dBuV FR:1508.
SAT measurement Locating Satellites With the SCAN function, satellites, the exact transponder frequencies of which are unknown, can be located. In doing so, the frequency range from 1000 MHz to 2100 MHz is continuously scanned for received signals. If signals are received, the reception level is displayed as a bar graph. The measurement range may be adjusted to three different sensitivity levels.
SAT measurement Bearing for Individual Reception Frequencies The „LEVEL ♫“ function allows the antenna alignment to maximum received signal via bearing. The level tendency can be bargraphdisplayed.The measurement range can be adjusted to three different sensitivity levels. The level can be monitored with an acoustic signal, the pitch of which is proportional to the received-signal level. The volume of the directional radio audio signal can be adjusted with the volume regulator.
SAT measurement SAT Analogue Sound Carrier Frequency Each video signal has several sound carrier frequencies assigned to it. Selective hearing of the sound maincarriers and the sound subcarriers is possible. The sound carrier frequency is tunable from 5.0 MHz to 8.99 MHz in 10 kHz steps. The soundcarrier bandwidth is automatically changed over from wide (280 kHz) to narrow (150 kHz) at 7.00 MHz.
SAT measurement DVB-S MER, BER and Offset Measurement The modulation error rate (MER), the bit error rate (BER) and the carrier offset can be measured to rate the digital reception quality. Chapter ‚standard change-over‘ describes how to select between SAT/analogue and DVB-S. Calling up DVB-S measurement: Press [2ndF] [DVB] in SAT reception mode LC display: MER:12.6dB BER:1.7e-7 MHz + 0.72 • (MER) modulation error rate: 12.6 dB • (BER) bit error rate: 1.7e-7 • Carrier offset +0.
SAT measurement LNB Voltage and 22 kHz/60 Hz Change-Over The LNB supply voltage can be obtained from the RF socket. For checking purposes, the LED beside the RF socket flashes when the voltage supply is switched on. The power consumption of the connected LNB is displayed on the LCD. The additionally connectable 22 kHz square-wave signal or the 60 Hz square-wave signal respectively will superimpose the LNB voltage when connected. It is necessary, e. g.
SAT measurement Example ✐ Activating the 22 kHz signal: Press [2nF] [LNB] [8] LC display: LNB:14,0V 150mA 22kHz • LNB voltage: 14 V • Power consumption: 150 mA • 22 kHz signal activated Note By pressing [8] again, the 22 kHz signal can be deactivated. ☞ By calling up a different function, e. g. [2ndF] [CH-FRQ] or 2x [2ndF], the LNB menu will be closed automatically.
SAT measurement DiSEqC™ (Digital Satellite Equipment Control) The DiSEqC™ system is used for control systems with extended control facilities. DiSEqC™ utilises a serial, bidirectional transmission mode with one master and one or more slaves. The data bits are generated with pulse width modulation of the 22 kHz carrier already existent, and are superimposed with 600 mVpp of the LNB remote feeding voltage.

The volume of the directional radio audio signal can be adjusted with the volume regulator.
TV measurement Sound Carrier Distance and Sound Carrier Level On a second sound carrier, TV broadcast stations can transmit either frequency-modulated (analogue) or in Nicam format (digital). Depending on the standard which has been set, various frequencies are assigned to the sound carriers, see table. Sound carrier 1 is permanently set after the channel entry or frequency entry. Standard B/G D/K I M/N L M1 (Japan) TT1 5.5 MHz 6.5 MHz 6.0 MHz 4.5 MHz AM 6.5 MHz 4.5 MHz TT2 5.74 MHz 6.26 MHz -----4.
