Defective V8 Finder Pro?

[caramel]

Hi, I just got my V8 Finder Pro 2 and noticed that the device is picking some interference by looking at the spectrum without connecting to an LNB. Is this normal or the device is defective?
I also ran the spectrum analyzer in a state park without any electronic devices nearby but still got the same pattern.

Connected to a Directv dual band Ku LNB and the interference went worse.

It's normal, we are surrounded by electromagnetic signals

Now you have signal that always has noise, C/N tells you how separated it is
You must ensure that the signal is between 47 y 77 dBuV After checking that the MER is as high as possible, which will be what gives us the quality.
Check these parameters that I have told you and you will have aligned the signal well, If you do not get good results you should check the components, cable, F connector, antenna socket, etc.
