[hpsdr] picoPSU Noise Test - well, I still think they're cute.

[Eric Ellison]

Hi Chris!

 

Wow! Stinks! Any options you can see for shielding? I wonder if it feeds
through to outputs? Goodness Gracious!

 

Thanks

Eric

Not so good.

The above is a picture of the test setup. I used 5 turns of #20 magnet wire
left over from the PA-100 Filter Module, attached them to 6' of RG-58U coax
through a bannan plug-to-BNC adapter, and draped the coil over the
picoPSU-60-WI. The other end of the coax went directly into my SDR-1000.

{If this is too big to download, I'll break it up.}

 

The above is the test result at 160m. Noise floor goes up 30db. Nuts. I
could do more, but is there any point?

P.S. - Any other ideas?
