Those analogue oscilloscopes are still very usable devicesnowadays.

It can be used to test cables, AC power levels and Batteries.

You'll often find yourself out on the road with problems that are causing you grief, but you aren't quite sure why.

You can use an oscilloscope to analyze signal waveform, get some idea of signal frequency and many other details.

Scopes are ment for looking at the qualitative aspects of the signal (like signal waveform, esitence of signal, etc.).

Pressure transducers, accelerometers, temperature sensors, and linear-position sensors are often imperfect devices, prone to nonlinearities and gain and offset errors.

The alias theorems: practical undersampling for expert engineers - Aliasing, long considered an undesirable artifact of an insufficiently high sampling rate, is in fact a useful tool for lab testing and analysis.

Deviations as high as ~3% or more are considered "in-cal", and in uncalibrated scopes this can be much worse.

Traditional oscilloscopes used a CRT screen and were completely analogue devices.

The two top contenders for the instrument-interfacing standard of the future are Ethernet and USB. Scopes that offer communication ports other than IEEE 488 are becoming increasingly common.

The current and most likely future leader in replacing IEEE 488 is Ethernet. The most obvious reasons for turning to computer-standard interfaces in place of IEEE 488 for instruments are cost, size, cable length of instrument networks, and increasing difficulty of installing specialized peripheral controllers in newer PCs.

For making quantitative measurements, a scope is "usually" a bad choice (for example multimeter is more accurate tool to measure DC voltage levels than a scope).
