what is an oscilloscope ?


An oscilloscope is a combined measure to visualize a variable signal in time. It is used for displaying electric voltages, electric currents and other variables processed by a converter. There are two types of oscilloscopes:
  • The analog oscilloscopes directly using a multiple of the input voltage to produce the deviation of the slot
  • Digital oscilloscopes that transform any treatment of the voltage input to a number
how to choose a good oscilloscope ?


There are several types of oscilloscopes in the electronics market, which can become a headache for engineers who want to buy a good oscilloscope with adequate features for their use, to choose the right oscilloscope please follow these tips :
  • The use will be used in a lab, in a client or in a car.
  • The number of signals to be measured.
  • The range of voltages to be measured.
  • The maximum frequency to be measured by the oscilloscope (bandwidth).
  • Signals going to present in time or frequency domain.
  • The sampling rate for digital oscilloscopes.
  • The relation between memory and the sampling rate.
  • The resolution and accuracy of the oscilloscope.
