For and NSA do you HAVE TO use an identical pair of antennas?

NSA 65-6 does indeed show identical antennas. Since shielding effectiveness
is a relative measurement, if you had a knowledgeable customer and you used
complimentary antennas (covering same frequency range and with same
polarization and not ridiculously high gain that puts one antenna in the
I don't think you Have To, but I highly recommend it.
We use a set of identical antenna pairs that we send out to perform NSA at
Liberty Labs large OATS site in Iowa to acquire the antenna factors. When we do
NSA, we open velvet lined golden caskets housing these antennas, perform the
NSA
Big mistake on my part my apologies. I was confused on acronyms and was
thinking of NSA 65-6, a spec on measuring shielding effectiveness. I now
realize from context below that the question pertained to normalized site
attenuation and concur that this is done with identical antennas.

I'm in the market for a good reasonably priced Temp/%RH/AP meter/recorder
device which I can easily and directly read from my computer with Labview. Any
suggested brands and model numbers?
I want to read the values directly so programming command information is a
must. SCPI, Ethernet, Serial,
I'm also interested in this type of recorder. Please include me in any
responses.

By degrees, I will be placing my inventory of test lab equipment onto

I have used the Vaisala (sp?) stuff. They make some nice modules where all
three sensors are embeded in same assembly and do I/O via RS232,422, or 485;
which I like to use on a current loop. Nice range and accuracy for most labs
inhabitable by humans.
As for LabView, meh - would be more apt to
Hi Rich:
Thanks for responding to my request for an explanation of the logic
behind allowing SPDs across isolation barriers.
Overall, the principles you outline seem reasonable if the equipment has
a reliable earth connection. I'm not yet convinced that these
principles adequately address
