"Just triggered a nit pick hot button for me... "lab-grade"... what EXACTLY
does that mean?"
Well, to me it means similar in accuracy to the kind of equipment I used in
the RF lab back in my working days. If you take a look at the ARRL review,
they found the AMI4170 to have "exceptional" accuracy comnpared it to their
Agilent 4291B impedance analyzer. And they also went back and re-checked
their reference loads because the AIM4170 was giving better results than the
Agilent at some impedances.
For what it does and for the types of measurements I make, I consider the
AIM4170 to be "lab grade". But maybe my definition isn't accurate. I have
been wrong before (at least that's what my XYL says)!
