I don't think using your 8640B as a signal source to read on a wattmeter
is going to cut it. +20 dBm is only 100 mW. Unless you have a
wattmeter that has a 100 mW or so range, you aren't going to get much
needle deflection. The lowest range on my Telewave wattmeter is 5 Watts.


Agreed. I'm looking at some RF log-amp chips from various places and
some RF sensor chips I saw in a construction article I can't locate
right now, so that I can get something useful with signal levels in
the Part-15 range.

I don't know what I'll wind up with, but it'll be interesting. I'll
share when it's soup.
