ezCol, the data collection part of ezRA suite (Easy Radio Astronomy, GitHub – tedcline/ezRA: Easy Radio Astronomy), looks like it measures voltage rather than power so dB calculation 20x not…

I used a NanoVNA vector network analyser to analyse my spare Nooelec SAWBIrd H1 low noise amplifiers. In each case, the level is around 0dB – so, when 40dB attenuation…
Hi Andy, Sorry I’ve been driving all day so just seen this. I hope I’m not teaching you to suck eggs, but it seems from some of the posts that…
As 40dB attenuation in the circuit, then need to add 40dB to reading on VNA. Once this is done, it is clear that the SAWBird produces roughly 40dB of amplification…
Those are called anti-static bags or ESD (Electrostatic Discharge) bags. They are used to protect sensitive electronic components from static electricity damage during storage and transport. There are two main…
