  1. Oscilloscope waveforms

    Tech Tips

    Oscilloscope waveform samples are provided here for informational purposes. Noise and fluttering waveforms have been omitted.


    1. A01MRP5N02

      Waveform 1

      Item Content
      Terminal k1-2 (BTH+) - k1-5 (GND)
      Equipment Setting 2 V/DIV., 500 μs/DIV.
      Condition Power switch on (IG)

      Tech Tips

      The waveform will vary depending on the content of the digital communication (digital signal).

    2. A01MS0HN02

      Waveform 2

      Item Content
      Terminal k1-3 (BTH-) - k1-5 (GND)
      Equipment Setting 2 V/DIV., 500 μs/DIV.
      Condition Power switch on (IG)

      Tech Tips

      The waveform will vary depending on the content of the digital communication (digital signal).

    3. A01MTVHN02

      Waveform 3

      Item Content
      Terminal k1-8 (FP) - k1-5 (GND)
      Equipment Setting 5 V/DIV., 1 ms/DIV.
