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?
