I have seen and tried this unit, both in the field at AmTech day 
(http://fars.k6ya.org) and at the Timewave Pacificon booth, and know the 
pepole (Dale NX6S et. al.) who designed it.  It is very nice.  I want 
one, but is expensive.  If I had a lab budget I would get one.

At AmTech day I hooked a piece of twin lead to it and got the frequency 
it was 1/2 wavelength on.  It agreed with my Autek VA1 but had a few 
more decimal places, and was much easier to use, giving the results in 
real time.  Dale also said I could have terminated it in a resistor and 
gotten a Smith chart for finding the characteristic impedance, also in 
real time.

At Pacifocon, I hooked a Maldol 20m whip to it, saw two dips in the SWR 
curve (one at about 16MHz and the other somewhere equally useless, 9MHz 
I think).  I clipped a foot of bus wire to it (I trick I think I learned 
from N6KR at a PAARA club prsentation) and the dip went down a bit but 
not to 14MHz.  The analyzer showed me this graphically in real time on 
its screen, and also on a computer which was slaved to it (though not 
required).

Then I walked off with Dale's BNC connector.  (I couldn't fit the 
analyzer in my pocker.)
