Zero Signal Quality Despite 90-100 Strength on Nbox Decoder with Hotbird, NC+

Question

Hello. I have a decoder Nbox , the decoder is working, I wanted to connect it to a new antenna in another apartment. New 80 cup (ellipse, egg), new converter black premium selected single 40mm lnb , new converter mount and wall mount, cable, new connectors. The problem is that the signal...

Call a technician with a meter.

Do not trust the indicator on the antenna. Everything would be fine if the mast was perfectly vertical, which it certainly is not, and the antenna holder would be made with perfect accuracy, and it is not. All these errors mean that despite setting to the indicated angle, the signal will not be. Try to slightly change the angle up-down and then left-right.

Do you have a vertical mast? Besides, it is only indicative. As you can see, reading alone is not enough. Experience is still needed. So it should be upright and not that would be good. I use a spirit level for this.

I have the handle on the side wall, when I screwed it on, I used a spirit level.

I caught the signal, there is a point that the quality jumped 14-30 when I turned the dish more steadily that it did not move, at this point it caught 98% signal strength and 60% quality

I am surprised and worried that at this antenna position the BER value is 0%
a STRENGTH 90-98% and QUALITY 60%
Why is BER zero?

The spirit level, like every measuring instrument, has its own measurement error. Are you sure you set it to Hot Bird? The compass also has a measurement error.

The channels are rather all, there are probably no channels that I do not have in the package, I got a message that I was connected to the Hotbrid satellite. What does the BER ratio give you?

Fotodetektor · Answer

Bit Error Ratio (BER). The BER bit error rate is a parameter that determines the quality and reception of digitally broadcast programs (e.g. with QPSK modulation, which is used in the DVB (Digital Video Broadcasting) system). In practice, it must be greater than 10-3 for the reception to be possible at all, while the value of 10-9 guarantees perfect reception, which corresponds roughly to the C / N value of 7 dB and 12 dB respectively. A bit error rate of 10-9 means that only one in a billion of transmitted bits may be misrepresented. Due to the use of FEC (Forward Error Correction), the BER value to ensure correct reception quality is variable. The measurement is made with a meter with a special BER measurement function.
