Antenna Analyzer AA-330

We introduce you a brand new device created for antenna analysys AA-330 (freq. range: 1 - 30 MHz).
Series of efficient schematic and mathematical innovations made a complex architecture that sucessfully satisfies all the needs of radio amateurs and professionals as well.
For example, measure-bridge is feeded with 1.8 AC voltage, that is tracked with the precision of 95% with any appliable input (even if it's a short-cut). This allows us to get values with precision of 97% (provided we have 100 Om input) and of 90% (provided we have 300 om input.

Device is made on ATMEGA(AVR) microcontroller, features:

- Measure range: 1 - 30 MHz
- Consumes – 9.0-15 V (via DC adapter or external batteries) 160mA - 200mA (depends on LCD backlight)
- Hardware check of the voltage to batteries
- Active resistance limit: 500 Om
- Reactive resistance limit: 500 Om
- SWR limit: 10
- Size: 110x55x190mm
- Weight: 300g
- DDS synthesizer,
- linear amplifiers,
- differential bridges with high-precision resistors,
- LCD display
- Analyzer allows to work with 50 and 75 Om wires (switchable bridges)
- Shows reactivity sign
- Sound signal that lowers its tone while approaching minimal SWR value
- Scans predifined and user-supplied frequency ranges
- Display shows resonance frequency, SWR, active and reactive components
- Device capable of manual scan mode (walk with frequency step of 1,10,100 and 250 KHz
- LCD backlight can be turned off
- Analizer allows to measure feeder length (from 3.5 to 100 meteres)
- Measures conductivity (up to 1000 pf)
- Measures inductivity (up to 20 microH)
- Measures band filters characteristics and resonance sidebar

Device can be operated manually or via PC (RS-232, COM port).
We provide quality software with graphical user interface. Here you can see some screenshots:
