This
project is upgraded to AAZ-0217MX
AAZ-0217A: 3 to 60MHZ Antenna
Analyzer
AAZ-0217A is a simple single
board USB Antenna Analyzer using Si5351 signal source generator chip
and a return
loss bridge, for measurement by a Log Amplifier AD8307
This Revision :
1. Uses Si5351 as a signal
Generator. Lower freq limit to 3MHZ as strong harmonics below 3MHZ
may not be suitable for measurement. Upper limit of 60MHZ restricted
by LPF.
2. Dual, auto power select option: PC use or Portable
use
3. Optional Bluetooth module (HC05):
Activation function
auto selected when module inserted into FRC16 Socket.
4. Project uses Si5351
chip on a plug in module which is supplied fully assembled and
tested for kits.
5. Technically restricted to
upper limit of 60MHZ but FW/SW is capable of generating
160MHZ. Similarly, lower than 3MHZ available but with poor
results.
6. Expansion socket (FRC16) is
for future use of a Bluetooth add-on module or a WiFi Module, with
necessary changes in FW. Supports RX/TX and I2C + External Power
input.
A PC program for WIN7/XP is available for
AAZ-0217A. Works well with WIN10 too but may require user to set
necessary permissions for WIN10 OS. Latest dotnet update is essential for your WIN OS.
Firmware V1.02 and Software V 1.02 for AAZ-0217A is
developed by Tony/I2TZK.
A free metal case is supplied with
kits/assembled.
