  • Slide 7
  • Trigger Sawtooth Positive trigger level
  • Slide 8
  • Trigger Sawtooth Negative trigger level
  • Slide 9
  • Trigger Sawtooth Part of the signal: less than one period Hold-on time
  • Slide 10
  • Trigger Sawtooth Part of the signal: more than one period
  • Slide 11
  • Dual Trace oscilloscope Use a single-beam (one electron gun). Time-multiplex the inputs. Chop mode or Alternate mode. Chopped mode: during the same sweep period, alternate between the two input signals. (better for slow sweep, i.e. high period) Alternate mode: one sweep period for each signal. ( better for fast sweep, i.e. low period)

  • X-Y mode X Y V y =A sin( t) V x =A sin ( t+)
