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.
