Since I didn't pick the correct numbers for last week's big Mega Millions drawing, I am again looking for cheap equipment.
I remember seeing a home brew "relative" noise figure meter somewhere. It would not give you an absolute noise figure number, but it would move a needle one way or another to show how your tweaks are affecting the noise figure of the device under test.
Does anyone know what this is or where I can find a link to it?
Thanks, Tyler KM3G
Hi Tyler, KM3G
Here is the description of a serious and simple Noise Figure Meter that you can build with easy
And here is the schematic diagram
I use this Automatic Noise Figure setup with success.
