Oscilloscopes

• Measure voltage as a function of time

  • Vertical scale is in volts/division
    • Set using scale knob
  • Horizontal scale is time/division
    • Set using timebase

• You tell the scope when to acquire data

  • You trigger the scope
    • Tell it to capture a 10,000 point waveform (Normal mode)
  • The trigger can be any event
    • Another signal
    • Some feature of your signal
  • The trigger must be correlated with your waveform
    • Else successive acquisitions will look random
