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?
  From the 1.999 M$ left buy a nice house?

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

 
Well, any complex wafeform can be shown to consist of sinusoidal harmonic components.
I have used FFT and than removing a spectral line and then a reverse FFT for video processing...
not in real time though... All depends on bandwith.
I mean if you have a 100 GHz signal and want the _waveform_ of that signal you will need to be able to see higher harmonics
than that
up to 1000 GHz for the tenths harmonics.
 
But if it is a repeating signal you could mix down and get the amplitude for each harmonics...
and then reconstruct the waveform from that

Yes, but you do also need to keep track of phase in order to
reconstruct the waveform.

Good point, we need experiment?
If you can sell it for 2M$ maybe worth a try...
