Oscilloscope Delivers 25-GHz Bandwidth on Four Channels
  
    https://www.electronicdesign.com/technologies/test-measurement/oscilloscopes/article/55247306/electronic-design-pico-technology-oscilloscope-delivers-25-ghz-bandwidth-on-four-channels
Pico Technology expanded its PicoScope 9400 Series with the PicoScope 9404A-25, a high-performance oscilloscope with 25 GHz of
bandwidth on four channels. The company's Sampler-Extended Real-Time Oscilloscope (SXRTO) technology integrates real-time
acquisition with sampling oscilloscope capabilities. Thus, the scope can trigger directly on the signal while recording pre-trigger
data, with the high time and amplitude resolution of a sampling scope.

When I want to see 10 GHz signals I use an old 5 dollar LNB and downconvert to about 1 GHz...
that into a 35 dollar RTL_SDR stick.
I know it is not the same, but 100 GHz downconvert should not cost hat much more
At higher frequencies lasers into non linear crystals as mixer?

Very nice idea, but that will work only for sinusoidal signals, right?

 
There were some superhet oscilloscopes that split the input signal
into bands with RF techniques, namely downconverting bands and
digitizing them, then somehow putting that mess back together
mathematically. Of course, one was a LeCroy.
 
Integrated shockline samplers killed that idea.
 
But 100 GHz electrical signals barely exist, so the market is small
for those megabuck scopes.

I should be possible to abuse a cheap fast latched comparator as
a sampler with ~10GHz bandwidth or so. Something like an ADCMP580.

I've done that and have a PCB, TDR actually. It seemed to work but I
haven't had much time to play with it.

Does anyone want to take over and see how well it actually works? I
guess it could become a product.

It's one of those tiles.
