This provided much faster control of the electron stream, enabling analogue oscilloscopes to achieve very high frequency operation. The form of cathode ray tube used on oscilloscopes employed electrostatic rather than magnetic deflection of the electron stream. Cathode ray tube as used in an analogue oscilloscope Accordingly it was used in television sets for many years, although other forms of display including LCDs, LEDs and many other format are now used, but these all require digital signal inputs to the display. This form of display was for many years the only viable form of display that could be used to display images. The key to the operation of an analog scope is its display. A vintage analog or analogue oscilloscope Analogue scope basics In some instances analog scopes can still be bought new, although the number and selection of these test instruments is fast reducing. However these test instruments can still be used to good effect in many situations, some people preferring to use them against more advanced digital scopes.
Often analogue scopes may be put to one side in a stock of laboratory test equipment. These analog or cathode ray oscilloscopes may not have all the functionality of their digital cousins but they can still provide the capabilities required for most laboratory and general test applications. The analogue scopes are also often called cathode ray oscilloscopes and this can be abbreviated to CRO.
