Re: NanoVNA-H4 Port Measurement
Had anyone tried placing 3 or 6dB attenuators on the ports? You lose dynamic range but you don't have to fool around with the NanoVNA? Mike N2MS

Re: alligator clips
For clipping allicator's nails probably. In finnish language we use pike's (the fish) jaws, they are more common here.

Re: NanoVNA-H4 Port Models
Thanks, Jim. But I truly believe economists can't handle anything other than linear. When Pat, my wife, was taking economics in college, she asked the question of her prof for me. The answer came

Re: NanoVNA-H4 Port Models
I refer you to Norm Augustine's famous paper where he plotted cost of military systems (aircraft carriers, airplanes) on log scale and it was linear. And from that, he inferred that in 20xx ( I can't

Re: NanoVNA-H4 Port Models
Yes, indeed. Why don't nations, especially the US, use dB and logarithms in their budget figures??? Can the economists not handle anything other than linear units?????? Dave - dB[W?LEV]

I find test jigs that you have to solder to fine for instructional purposes but not practical for bench for field applications, or to measure large components such as variable capacitors or coils. I
