I have to add another comment here since I was extremely pleased with professional and lightning fast support provided by RigExpert team.
TDR download and phase angle issues were resolved almost immediately after being communicated.
Firmware and program updates were released the next day. Phase angle values are now calculated with proper accuracy and TDR data are read flawlessly by PC.
Well done!

I have purchased AA-230PRO from Rigexpert net in Canada, who kindly offered me some discount.
The instrument is definitely not cheap, but its price is reasonable, considering its value.
However, I do not share Administrator’s optimism who hopes that “it is already far away from its competitors”. It does not, and I am not intended discussing it here.

The instrument’s main advantage - its hand-held design and quite accurate readings of SWR and (most of the time) load impedance with ability to distinguish a sign of reactance, e.g. tell the difference between capacitance and inductance.
The only difference between AA-230PRO and AA-220 that I have discovered was ability of AA-230PRO to calculate and to display on LCD the Time Domain Response which indicates the distance between the instrument and a problem in transmission line. That is really great tool.

While tuning KT-34 antenna I compared AA-230PRO SWR readings with IC-7600 and
Daiwa CN-801HP SWR meters. AA-230PRO demonstrated perfect match with its Japanese colleagues.

I also tested instrument’s abilities to interface with PC. AntScope program was capable of downloading and displaying data from the instrument, such as SWR, Return Loss and Impedance com... read more »

Administrator comment: Dear Evgeny, please see the Downloads section of this website for new versions of the firmware. The "95% bug" is fixed in version 306.

I Thing is a good tool and the right direction. If on this product you add and the Freq Range of UHF(410-480 MHz)then becomes far away from it's competitors.

Administrator comment: Dear Alex, we hope it is already far away from its competitiors. :-)
