Default Field strength meters

I've never had a spectrum analyzer measure field strength directly,
although maybe the Test & Measurement science is getting close. The
missing link is "antenna factor" (AF) which accounts for the db gain,
usually negative, for the antenna you're using. In my experience,


There are both EMC receivers and Spectrum Analysers intended for field
strength measurement, and modern digital system allow the antenna
response to be stored in the instrument and field strength automatically
calculated for different freqencies.


Thanks, Owen,

I read online that there were EMC receivers that would store the AF curves,
but I happened not to read that there were spec-ans that would, too. I
haven't done that work in over ten years and we rarely had state-of-the-art
gear. (Can you say, "Singer NM-25"?)

Glad to know it's all getting easier.

Now, if we just could hook an X-Y plotter up to it ... Relax, I'm just
kidding!
