I'm working on resurrecting a Wiltron 6600 series sweeper (10 MHz - 18 GHz) with multiple problems (I think it was a combination of salvage parts).
My old systron donner 762-2A spectrum analzyer (and a 436/8484 power meter) have been helping, but it occurred to me that the TinySA Ultra might help (as in detecting presence of a signal) as well, and perhaps aid in validating the sweeper's output (through appropriate attenuators; the YIGs can kick out +15..+20 dBm.)
I'm curious as to how the original ("405"?) version Ultra can be expected to behave when encountering a (single) signal (a sort-of stable carrier from a fundamental-mode YIG oscillator) far above the ~5 GHz Ultra-mode ceiling?
I suspect this has been covered (either by developer, by experimenter, or both) but my searches in the group archives didn't yield anything that might apply.
Thanks!
