I am user of the ECO 150XA-6, and it is quite amazing what this little thing does. I discover signals I did even not know that they exist, like radar signals from the airport, a defective commercial UHF repeater that spits out nasty spurs at each key-up, harmonics of the LO of my pager and all kind of weird stuff. Having up to four bands of interest in near-realtime is real fun, and the sensitivity is overwhelming.
Now I wonder if there are some hardware insights, without opening the device and doing my own research. I know the block diagram, but I really would like to know what parts are used for amps, mixer, LO, ADC/DAC, how the filter bank and its switching is designed and such. From the performance I would not expect a complete transceiver chip like the well-known AD9-something or Lime, but a more discrete design of mixer, LO, ADC/DAC.
Is something like that availabe somewhere?
Thanks a lot for this great piece of work!
