  • Page 48: Triggering

    OPERATING INSTRUCTIONS TRIGGERING The oscilloscope provides versatility in sync triggering for ability to obtain a stable, jitter-free display in single-trace, or dual-trace operation. The proper settings depend upon the type of waveforms being observed and the type of measurement desired. An explanation is given to help you select the proper setting over a wide range of conditions.
  • Page 49 OPERATING INSTRUCTIONS Trigger SOURCE Switch The trigger SOURCE switch (CH 1, CH 2, etc.) selects the signal to be used as the sync trigger. 1. If the SOURCE switch is set to CH 1 (CH 2) the channel 1 (or channel 2) signal becomes the trigger source regardless of the VERTICAL MODE selection.
