A question about GTmedia v8 finder 2

Post by xmh0511 »

I prepare to purchase a v8 finder 2 since it looks good and has the spectrum function. Before that, I have a question: what minimum number of signal quality can it detect and show on the progress of Signal Quality? I have watched numerous of the testing v8 finder2 videos on youtube, and what I can see is the quality number will suddenly turn green(i.e. be locked) without any low number shown during the process of aligning the dish. I doubt whether v8 finder 2 can help me find the satellite with a weak signal. Specifically, can it show the quality such as 5%, 6%, or so on during the detection of the signal? If it were not, what the minimum number can it print? Please answer this question, I really like this machine.

To align a satellite, it is located in 5 seconds, then it is necessary to adjust altitude, azimuth and polarization, the most important data is the MER that varies depending on the MUX, the minimum is 8 dB, acceptable >12 dB, always check the weakest signal, use an FTA channel

Could you please tell me what the minimum signal quality number it can start to report? I don't know what MER does.

It is a fact that is not important, the minimum PWR is 47dBμV

The modulation error ratio for DVB signals (MER) is the measure of the quality of digitally modulated signals

Thanks. How to understand the number of PWR and MER during the alignment of a dish?

for DVB-S data measured in the final shot
PWR >47dBμV ideal >80dBμV
BER 1,00E-O4 to 0.00E-00 ideal 0.00E-00 (no error)
MER >8 ideal >12dB
C/N >11 ideal >12dB

For DVB-T the data is different

what the number of the signal quality would be If PWR were 48dBuv and MER were 9? I mean what the case would be if the signal is on the edge of the minimum number the instrument can solve?

In case of inclement weather, it is more sensitive to losing the signal
