Hello Ed -

You are correct - the factors stored in the probe correct for
the non-linearities of the diode detector.

It is not surprising at all that it takes less

Anything "antennas" is checked in the far-field -- especially if
testing for accuracy.
I'm a BIG fan of near-field probing for relative measurements and
localizing emissions, but we use probes appropriate to what we are
looking for; if I wanted to "calibrate" one there,
IMHO all probes are calibrated under far field conditions.
In general: Using probes in the proximity (< lambda) of anything
conductive (including ground planes at 10 cm and including EUT) makes
the measurement data useless.
As James correctly states, the construction of the probe makes this
Hi David,
An interesting set of results! I'm going to ask some questions that I'm sure
you've already considered so please bear with me being Captain B. Obvious.
Do your field probes use frequency correction? I'm not familiar with a wide
range of probes but my Narda PMM field probe has an
