[time-nuts] Software defined spectrum analyzer

[Don Latham]

Hi Luis:I, too, am curious. But I haven't opened it yet. I suspect
something like an FPGA feeding a fast a/d somewhere in the 50-70 MHz
range. That is, a decomposition.
There may be a synthesized LO and mixer to get to the 50 MHz.
The info on the website says or used to say something about an sdr
modified to act as a spectrum analyzer.
One of the things I like about the device that played a part in my
purchase is the availability of a 10 MHz reference input. as a good
time-nut that shows some serious engineering attention to accuracy.
