Page 23: Measuring The Optical Power
NOTE: As with any receiver, the presence of several high-level channels within the reception band can generate spurious signals. If the operator does not use the attenuator appropriately under these conditions, in the case of automatic measurements, frequencies which are not actually occupied by channels could be measured at an unexpected level. -

6. DEMODULATOR CARDS FOR DVB-S/S2, DVB-T/T2, DVB-C 6.1. INTRODUCTION The modulation systems adopted for digital signal transmissions are optimized for the various types of transmission: • QPSK/8PSK: used for satellite transmissions due to their significant resistance to noise; • QAM: used for cable transmissions due to their particular efficiency in taking advantage of the available band;... -
Page 37: Use Of The Card
NM: (Noise Margin) indicates the value (expressed in dB) of the reception margin. The greater the value, the greater the reception margin. RU: number of errors not corrected (from 0 to 65535), followed by the indication of the time during which the errors were counted. The timer, as well as the indication of the errors, will be reset when the QPSK signal is not locked. -

6.3. MEASUREMENTS IN OFDM (DVB-T/T2) OFDM is the name of the transmission system adopted in Europe for the transmission of digital television signals over the air. The features of this system can be summarized by the following: • Occupation of a channel frequency equal to that of the current analogue transmissions. •... -
Page 39: Nm (Noise Margin)
6.3.3. NM (Noise Margin) The Noise Margin is a calculated estimate (in dB) of how much the carrier/noise ratio can deteriorate before reception will be compromised, based on the set reception parameters and the measured MER. The higher the noise margin, the lower the possibility of encountering any problems. 6.3.4. -
Page 40: Aer (Adaptive Equalizer Response) In Ofdm
While the OFDM card is function, the tuning frequency can be changed, like for UHF band in analogue. It is necessary to keep in mind, however, that the instrument’s response time is longer in digital mode. When storing a program, by pressing the 2nd and STORE buttons, the digital parameter settings are stored as well, along with the other usual values like frequency, etc. -

8. MPEG4/MPEG2 DECODER 8.1. Introduction The MPEG card allows for unencrypted digital transmissions to be viewed. This however is not the most useful function that it performs within the instrument in which it is installed, as the quality of a digital signal cannot be judged by the video image, but only by means of specific measurements like the BER or the C/N ratio (albeit much less reliable and accurate). - Page 47 NOTE: Certain programs may not be transmitted as declared. In such cases, the corresponding line may be green despite the fact that the signal is encrypted, or vice versa. AP401FULL- HD_rev. 09_UK...
