Oscilloscope History and Milestones
http://www.oscopes.info/background/2265-oscilloscope-milestones
Oscilloscopes have been invented in the 1920s. Up to now this instrument encountered many innovations.
Today the main players are Keysight, Tektronix and Teledyne LeCroy.

BUILD A ONE INCH SCOPE

What could be more fun than building a miniature oscilloscope? Not one with an LCD screen, but a scope with a real live cathode ray tube just one inch in diameter. All the parts — including two 6AU6 vacuum tubes — will be housed in a 5” x 7” x 2” box.
My inspiration came from the cover of a 1960 issue (Figure 1) of Popular Electronics.

This oscilloscope made history! Used to design both Pong and the Apple II.

USED TO LAUNCH THE DIGITAL REVOLUTION, TWICE: This oscilloscope was used to design Pong, the birth of the video game industry, and the Apple II, the first personal computer with hi-res color graphics. The present oscilloscope is a remarkable artifact, having played a critical role in launching two of the most consequential products in the history of the digital revolution.

Claim: Analog has much finer tuning and can see anomaly easier.
Paul Donovan I would say it depends. What you say can be true with some cheaper and older digital scope. But with high end digital scope you can tune it well, see anomalities easier and especially capture the anomalities when they happen. High end digital scope beats analog in anomaly hunting by a wide margin!
Infinite persistence can becused to catch all the glitches for that period of time. The digital scope can also be setup to one shot mode capture and show only the glitch when it happens. Waveform is stored in memory for analysis future reference.

When debugging your space electronics using an oscilloscope, many different measurement types are now possible, e.g., voltages, currents, power rails, digital logic, EMC, optical, TDR, and high voltage. For each of these applications, the specification of the probe that makes contact with your device under test (DUT) determines the quality of your test, e.g., its frequency response and bandwidth, how it loads the DUT, whether it matches the input impedance of your scope, where and how you attach the signal and ground contact tips. Often the probe is overlooked or taken for granted. During many of my visits to customers, I have seen the wrong diagnosis due to poor probing techniques or incorrect decision-making because of the specification of the oscilloscope and/or probe. Ultimately, this has impacted the ability of clients to deliver hardware and sub-systems to cost and schedule.
