"As I looked at things over the years, very few people want VNA's that
attach
to PC's, and that market is covered anyway. I thought a 259 revision wth
direct conversion receivers and a wide frequency range, and a calibrate
function, and just basically do what the 259B does now, would have been much
better."
The RigExpert handheld series of complex impedance analyzers pretty much fit
that goal. The AA-54 is in the same price class as the MFJ-259B and has +13
dBm output power. It doesn’t have the frequency range of the 259B but it
will accurately cover HF through 6m. At roughly 2x the price, the AA-600
gets you a serious 600 MHz handheld analyzer with OSL calibration and PC
graphing connectivity.
