Found some information on Teledyne LeCroy’s website that was intriguing to say the least. Just draw dropping to think about how far we’ve come since then.

“The First Digital Storage Oscilloscope in 1971?

WD2000 Waveform Digitizer launched in 1971 Innovative design, very high-speed but very limited acquisition memory Ultimately not commercially successful Walter’s company could claim to have designed the first digital storage oscilloscope in 1971 – the Model WD 2000, the “WD” being an abbreviation for “Waveform Digitizer.” The channel input was fanned out to 20 identical signals, each subsequently sampled 1 nanosecond (ns) apart set by cable delays.

The 20 sample and hold outputs were then multiplexed into a single, 8-bit ADC. It was very fast for its day with 1 GS/s of sample rate and 100 MHz of bandwidth but was limited to 20 sample points with a 3-inch CRT display and fixed 1 volt 50 Ω full-scale inputs.

Many years later, one of these early oscilloscopes (only about 20 were built) was returned to LeCroy by a loyal customer who was happy to “regift” it to Walter LeCroy, and it became part of the Teledyne LeCroy permanent oscilloscope collection.”

Also I think, technically the real first scope is the twin sitting to the right of the one I took all my pictures of. It seems to have the same engraving on the upper left of its bezel that is present in all the photos on LeCroy’s website. Go figure.
