New version of SMA Simple Spectrum Analyzer!

Here is the change log, it has been a productive night:

  • Corrected dBm calibration for improved precision
  • Implemented new function: Powermeter - not sure if it is correctly implemented
  • Implemented new graphics engine
  • Spectrum/Waterfall in main image can be saved as PNG
  • Introduced change log
  • Cleaned up GUI (Setup screen)
  • Cleaned up some code
  • Added a SET button on Sweep Generator (less prone to crash due to open RS232 port)
The picture shows ASTRA 19.2E, using the MIN/MAX and LIVE traces.
Refresh rate with 500 samples (quite a high resolution compared to common field meeter) is about 0.333 fps.
This picture shows the waterfall diagram of frequency range 144MHz-180Mhz


It uses the same activation code, in case you already have one. If not, just follow the instructions on first run.

Please give me feedback:
  • Does it work?
  • What do you use it for?
  • Suggestions for enhancements
Have fun!

Cheers,
Vitor
