Another salient question, I think, is are noise levels being compared at the same, or nearly the same, frequencies. Broadband LNAs tend to be noisier at higher frequencies than lower ones, and since the SBX have coverage up to 4.4GHz, it's not really "fair" to compareOn 08/09/2011 02:32 PM, Farrukh Aziz wrote:Hi, I have been working with SBX and WBX dboards for a while now. I have also experienced more noise with SBX.A number of people have reported this. We are investigating and will get back to you soon. What motherboard are you seeing this with? Matt
noise at let's say 3.4GHz, with noise, at, say, 1.2Ghz.
