Hi John --
I talking with the AEA staff, they mentioned that another box is in
development. This will do all that the VIA Bravo will do...
but it has connections for four probes in order to display relative currents
and phase when tuning up phased arrays. It should be
available in 9-12 months.
Maybe others have more insight about this?

Subject: Topband: New AEA impedance analyzer
Topbanders:
I'm considering buying the new AEA VIA Bravo impedance analyzer. Has anyone
tried one and have any recommendations, positive or negative, about it? I
saw it at Dayton and also obtained an operating manual from AEA. It
certainly looks interesting.
You can find some info at: http://www.aea-wireless.com/viabravo.htm. It is a
more capable analyzer than the less expensive CIA-HF model that I currently
own. It can measure complex impedance over a larger impedance range with
better accuracy than the CIA-HF. It also has non-volatile memory that allows
you to take the unit up the tower, make sweep measurements, store the data,
and later download the data to a PC. It has a pseudo-TDR mode that can
measure coax cable lengths (like the MFJ259B "distance to fault"
measurement), a spectrum analyzer mode, and a cable nulling function that
compensates for coax line length to allow measurements of load impedance
through a length of transmission line. The package also includes the
software for downloading and plotting measured data on a PC.
