With a decent vector network analyzer, the ports are already
well-known (50 Ohm) terminations. If the round robin you mention was
in the July 2007 time frame then I was a party and measured the device
using both my N2PK VNA and a Boonton RX meter. I have pictures of the
setups, but alas can't find the data. I got some feedback that you
said of my measurements, that they were "dead nuts on." :-)
Hi Wes,
Yes, that's the round robin I was referring to. Although my memory of it
was that the Boonton data was spot on, while other data was not. But
since you did it, I'll trust your memory over mine. :)
If your VNA data did closely match the Boonton data, we should talk off
list about your setup of the N2PK VNA, which is well known to be a fine
unit. I certainly would like a method I can trust that is a lot less
work than the voltage divider method.
73, Jim
