Ha - I actually thought that might be the reason it's set where it is ! (kind of like the number of bars on an iPhone..)

As long as I know what the rough calibration is then that's the most important thing.

I appreciate the technical detail and the openness of your responses.

Cody - thanks for the confirmation 14dB C/N corresponds to an Eb/No of 11.96dB with DVB-S QPSK R=5/6 - on the downlinks I was initially trying the box on the Eb/No is 11.8dB and 12.6dB which explains why I was seeing 98% on both. You might want to think about setting that scale a little higher such ...

OK - It does vary but the point where the readings max out is lower than 16 - not sure if you were referring to C/N or Eb/No in your note but either way in my tests the point where it 'rails out' is an Eb/No of 11.5dB I testedin a lab with a 30Msps QPSK R=5/6 carrier and measured the reported Qualit...

Thanks for the quick response

I'd agree that's likely if the Eb/No was 16dB or higher. However the Eb/No on both signals I tested with is around 11dB - I'll see if we can run some lab tests to see what's reported with a lower Eb/No level.

Just received QBox S2 and it works well - I found that it came with a support file for TSReader which is very useful. The only problem I have found is with the signal level reporting, when locked both Signal Level and Quality report 98% at all times in both TBS Veiw or TBS IP Data apps. I am running...
