Notes on Averaging
• Averaging is effective only against repetitive waveforms.
• Correct averaging is not possible if the waveform has imperfect triggering (incomplete
synchronization), and the displayed waveform will be distorted. When working with
this type of signal, set the trigger mode to Normal, so that the waveform display is
updated only when the trigger is activated (see section 6.1).
• Roll mode display is disabled during averaging.
• Averaging is not possible when the trigger mode is Single, Single (N), or Log.
• If you stop waveform acquisition by pressing the START/STOP key, the averaging
process also stops. Averaging restarts from the beginning when acquisition resumes.
• If you are using simple averaging, the DL750/DL750P terminates acquisition
automatically when it completes the specified number of acquisitions (acquisition
count).
• Averaging is not possible when the dual capture function is used or when realtime
recording is in progress.
• When acquiring waveforms in averaging mode, the data that is retained in the history
memory is 1 record.
