The IT-24 Image Capture tool has been updated to support AA-170 analyzers as well. The AA-170 analyzer uses a 128x64 1-bit display, a simpler image transfer protocol, and a slower baud-rate. The new baud-rate must be specified on the command-line.
Additionally, this software should work on several other RigExpert analyzers like the AA-30 and AA-54, and may work with AA-230 and AA-520 as well. If you have one of the above analyzers, I'd love to hear if it works.
RigExpert makes an affordable 2.4GHz analyzer. In an earlier post I documented the image transfer protocol. Today I take it apart.
Although RigExpert hasn't yet published repair diagrams or schematics for the IT-24, the design seems fairly simple and easy to repair. The main sections are RF(back of PCB near top), display(front of PCB near top), power(front of PCB near bottom), and digital/micro(back of PCB near bottom). There's a JTAG header to the ATMEGA128A, and except for the micro and FTDI converter, the other components are large enough to be manipulated with an iron. It would've been nice if the battery pack were attached with a connector instead of soldering. Coax-connectors are a standard part, which is great, since SMA and RP-SMA connectors are only rated for around 500 insertions. At one insertion per workday, they'll need replacement around every two years.
