oscilloscope 

A test instrument that shows a picture of electrical waveforms by means of a cathode ray tube. An oscilloscope is calibrated so one can measure the instantaneous values and waveforms of electrical signals that are changing rapidly or varying as a function of voltage or time. Also known as a Scope.

I use my oscilloscope to measure the waveforms of my 27 MHz band jamming transmitter.

High-Fidelity Oscilloscope 

1. An electronic device that is overkill or is grossly over-engineered for a given task. An example is a 200 megahertz oscilloscope on your $8,000 CD transport to view sound waves that are four orders of magnitude less clear.

2. Any expensive device bought to "improve" the performance of a system (not just a sound system), when only a small percentage of the potential of the added on device will be used.

They now have a "gaming" network card with a K-shaped heatsink on it, which is about as pointless as a high-fidelity oscilloscope.

So you bought a blu-ray recording deck to get crisp copies off your VHS tapes you taped off of UHF rabbit ears?? You might as well as bought a high fidelity oscilloscope to draw a graph of how often the furnace switches on.

Bob Dylan spent $2,000 on a new Karoke machine with the ribbon microphone,electrostatic speaker, and Akai open-reel deck, but I personally think he wasted his money on a high fidelity oscilloscope.

RiceBoy:My $250 Yugo has remote-start, DVD video system with navigation, and premium high-octane fuel in the tank, as well as an exhaust tailpipe big enough to fit an LP record album in sideways. MuscleCarMan:(sarcastic tone)You should put in a high-fidelity oscilloscope in next!

Oscilloscope 

Device that lets you see sound whilst still being sober.

Well, that’s a basic description of the function of an oscilloscope.

I'm going to Oscilloscope the fuck out of this painting!
