    Use only the mains unit that came with the device. SCART OUTPUT Via the scart socket on the front side of the MSK 125 the video and audio signals are available for evaluation on an external monitor. The [AV IN] button allows you to switch to audio/video input.

  • Page 14: Getting Started

    • Set the desired volume using the [Vol-] or [Vol+] buttons. For app. 1 second the LC display indicates the current software version and serial number of the MSK 125. Now feed the RF input with the reception signal from the receiver.

  • Page 15: Default Setup Settings At Time Of Shipment

    The next menu prompts you to set the mute function using the [1] or [2] button. If you select ON, the MSK 125 is switched to silent as long as the incoming signal on the RF input is below 30 dBµV.

  • Page 16: Battery Operation

    Battery operation is only possible if the battery is charged suffi ciently. Otherwise the MSK 125 cannot be switched on. Once the battery has fully discharged it must be recharged immediately to avoid damage to the battery.

  • Page 17: Sat

    ANALOGUE AND DIGITAL SATELLITE RECEPTION In SAT mode the MSK 125 can be adjusted to “Analogue” and “DVB S(2)” reception types. SAT ANALOGUE / DVB-S(2) SWITCH [SAT A/D] Press once = SAT analogue Press again = DVB-S(2) Press again = SAT analogue again...

  • Page 18: Sat Analogue" Level Measurement

    • Operating mode: SAT • Level: 86.5 dBµV (A = analogue) A “+” or “-” on the display means that the MSK 125 has not been adjusted precisely to the desired carrier. Use the [<] and [>] buttons to refi ne the frequency for optimum reception. A vertical line on the display indicates optimum frequency adjustment.

  • Page 19: Sat Dvb-S(2)" Level Measurement

    At a level > 120 dBµV the LC display indicates an overfl ow. The following details are displayed: • Frequency: 1508.0 MHz • Operating mode: SAT analogue • Level: Overfl ow Note The level of DVB-S(2) signals can only be measured properly with the setting “SAT digital reception”.

  • Page 20: Finding Individual Reception Frequencies

    Example Launching the “Find satellite” function: • Press the [SAT FIND] button. • Turn the antenna until a level tendency can be seen on the bar display. • Turn the antenna until the bar display reaches its maximum • If necessary, decrease or increase the sensitivity using the [<] and [>] buttons.

  • Page 21: Sound Carrier Frequency Setting

    SOUND CARRIER FREQUENCY SETTING Every analogue satellite video signal has multiple audio carrier frequencies assigned. On the MSK 125 you can listen to main and sub-audio carriers you choose. The audio carrier frequency can be adjusted from 5.0 MHz to 8.99 MHz in 10 kHz intervals. At 7.00 MHz the sound carrier bandwidth is automatically switched from wide (280 kHz) to narrow (150 kHz).

  • Page 22: Dvb-S(2) Mer (=Snr), Ber And Offset Measurement

    DVB-S(2) MER-(=SNR), BER AND OFFSET MEASUREMENT The modulation error rate (MER), the bit error rate (BER) and the carrier frequency offset (LNB offset) can be measured to rate the digital reception quality. Note: In this case MER shown on the display has the same meaning as SNR (signal radio ratio).
  • Page 23 The following voltages can be Button LNB voltage called up via button command: 12 V 14 V 18 V 22 kHz For checking purposes the LED right from [LNB CNTRL] button is on when the power supply is turned on. Press the [LNB BATT] button to indicate the power consumption of the connected LNB on the display.
