Const Menu Examples for QPSK constellation diagrams QPSK signal without faults QPSK signal with phase noise (LNC) QPSK signal with intermodulation noise QPSK signal with superposed broadband noise. Possible cause: Defective amplifier or high cable loss.
Const Menu Constellation diagram for QAM (DVB-C) For digital transmission via cables, the modulation type QAM (Quadrature Amplitude Modulation) is used. The MSK 33 can represent the constellation of the modulation types, QAM64 and QAM128. For QAM 64, every 6 information bits are put together to one symbol and modulate one carrier in its amplitude and phase. With this, 64 conditions are possible, which a receiver must recognise for correct assessment of a QAM signal.
Const Menu Frontend locked If the receiving part of the MSK 33 is locked on the carrier frequency of the received signal, the display, „Frontend locked“ appears on the screen. If a representation of the constellation diagram is not possible, the display „not locked“ is displayed. An analysis of the constellation diagram or an evaluation of the measurement results can first occur, when the receiving signal is locked. The modulation type and the symbol rate are to be correctly set.

DVB-T DVB-T Constellation diagram DVB-T (optional) For the terrestrial digital transmission of television signals (DVB-T), the modulation type COFDM (Orthogonal Frequency Division Multiplex) is used. In 2k mode, 1705 carries and in 8k mode 6817 carriers either QPSK-, QAM16- or QAM64 are modulated. DVB-T signals are transmitted in the so-called hierarchy modulation. Two MPEG transport streams of difference priority are simultaneously transmitted.
DVB-T Hierarchy Meaning: Two carriers streams are simultaneously transmitted and the transport stream with the higher priority is QPSK modulated. There are four hierarchy steps (0, 1, 2 and 4). Hierarchy = 0 menus, that the signal is not hierarchy modulated. Hierarchy = 1 means, that the signal is hierarchically modulated. Two transport streams are simultaneously transmitted, one has higher priority in QPSK. Hierarchy = 2 menus, that the signal is hierarchically modulated.
DVB-T Code rate Display the measured code rate ½, 2/3, ¾, 5/6 or 7/8. Guard Displays the ratio between guard interval and symbol time 1/4, 1/8, 1/16 or 1/32. Invers The display of the condition of the frequency spectrum or the constellation diagram. Setting occurs automatically. Frontend locked If the reception part of the MSK 33 is locked on the carrier frequency of the received signal, the display „Frontend locked“ appears on the screen. In the opposite case, „not locked“ appears on the screen.

Broadband Cable Analysis Measuring System MSK 33 / MVG Broadband Cable Analysis Measuring System MSK 33 / MVG The broadband cable analysis system consists of the antenna measuring instrument MSK 33 (including return path option) and the signal generator MVG 10. Both units function in the frequency range from 4.0 MHz to 860 MHz. It allows the measurement of cable systems in CATV range (downstream) and in the return path range (upstream). The measurement can also be carried out in the supplied cable.
Broadband Cable Analysis Measuring System MSK 33 / MVG First select the reception frequency in the reception menu TV or RP. With this, the MVG 10 begins to „sweep.“ TRACK. MVG10 From the MODE menu, man reaches track. MVG 10 the spectrum display in MVG 10 tracking mode with the second softkey. mvg10 only► In this mode, all MVG signals in respect to the frequency and level are recorded from the starting frequency up to the end frequency. In between, laying signals are not recorded.
Broadband Cable Analysis Measuring System MSK 33 / MVG A few functions such as „Clear display,“ „Printout the spectrum“ (prt 123) and switch-over functions can be remotely controlled via the MVG 10. Refer to the operating manual MVG 10! Comfortable upstream 4.
Broadband Cable Analysis Measuring System MSK 33 / MVG Retransmission of the spectrum received by the MSK 33 (1) with a MVG 10 (2). It is possible to transmit the received spectrum on the head station or a FBAS signal of an external unit (camera, head station computer etc.) via the MVG 10 (2) on free CATV channels. Here, the MSK 33 is connected to the MVG 10 with the fully occupied Scart cable. Please make sure, that the MVG 10 is two-sided band modulated.
