Output wave form and Test circuit

  1. Timing chart

    Timing chart
  2. Test conditions

    • (1) Supply voltage

      More than 150 s until voltage level reaches 90 % from 0 %.
      Supply voltage impedance is less than 2 of resistance.

    • (2) Oscilloscope

      Input capacitance of less than 15 pF.
      Frequency range of 5times or more of measurements frequency.
      Earth lead of the probe should be as short as possible.
      Probe impedance when measuring frequency is to be more than 1 M. Simultaneous measurement of waveform (frequency and wave form) is not possible; however, measurement is possible as the wave form passes from the amplifier stage of an oscilloscope.

    • (3) Miscellaneous

      CL includes the probe capacitance.
      Ammeter with small internal impedance should be used.
      To observe wave form, please use a miniature socket.
      (do not use a long ground wire of the probe.)
