 50MHZ Antenna Analyzer: AAZ-0616: USB and BT


A Project by:

Tony / I2TZKFrank / K7SFN , Dinesh / VU2FD


This project is revised to AAZ-0217 please visit ........


This Revision (AAZ-0616) has following changes to AAZ0914A board design:

1. HC05 Module directly fits on board 

2. Dual, auto select power option: PC use or Portable use: Standard USB or Mini USB from Power Bank (BT Only)

3. Bluetooth module (HC05) function auto selected when powered from Mini-USB/Power Bank

Except above mentioned three board changes, AAZ-0616 is basically same as AAZ-0914A.

AAZ-0616  uses same FW as last version AAZ-0914A, that is : V6.02.

A PC program for WIN7/XP is available for AAZ-0616. Latest dotnet update is essential. 

Firmware, Software for AAZ-0616 is developed by  Tony/I2TZK.

AAZ-0616 is a simple single board USB Antenna Analyzer using DDS signal as a source and a return loss bridge is used for measurement by a Log Amplifier AD8307

BT function is realized by using an HC05 module. However, its not possible to provide user support for BT operation as each android phone/tab has specific permissions and need that users do the necessary settings to their phone/Tab. BT operation is tested on Samsung Tab3 with good results.

A free metal case is supplied with kits/assembled.
