What's the threshold level of v8 finder2?

Post by xmh0511 »

I'm preparing to purchase v8 finder2. However, there is no detail about the threshold level of this product. I wonder what is the threshold level of this machine? Is it able to detect the weak signal?

The normal is between 20 or 30, enough so that you can measure the weakest signal of 47dBμV without BER and MER errors.

How about these signals that are weaker than 38dBuV? Can this machine recognize such signals and do the corresponding reaction?

Yes, that is what the Finder is for and put some appropriate values ​​for a perfect visualization of channels

Just one question, what's the minimum C/N number the v8 finder2 can detect and show on its screen? I take it as the threshold level of this machine. Did you test it for that?

It must be C/N>11dB, the important thing is the highest MER the minimum is >8dB, it prevails over the PWR power

I don't know whether it is comparable with other instruments. AFAIK, the threshold level of one finder I know is 4.1db. Presumably, it refers to C/N. Anyway, either C/N or MER whose unit is "db", are far away from 4.1db. Does it mean this machine is unable to measure such a signal anyway?

Measuring 4.dB will measure it, but you will have to improve the signal because it tells you that it will not work well if it does not exceed the minimum of 11dB

I understand your meaning. C/N>11dB is the minimum number that the video can be decoded, right? I asked what the minimum C/N "?db" the v8 finder2 can measure out and show the number on its screen? In other words, the down limit C/N the machine can detect. If you still do not understand what I am meaning, could you please tell me what the model of the tuner which v8 finder2 is using? I can look up the detail by myself.

The minimum C/N is C/N= 0.0 dB with decimals, this will tell you the Carrier/Noise ratio you are measuring.

0db is meaningless. What the minimum number that is greater than zero the machine can detect? I just concern that.

It makes a lot of sense, from 0.0dB to 10.9dB is a bad signal
You'll have to look up what components cause that under C/N
It can also be misalignment with the satellite
