1 The values inside the thick frame are for repetitive sampling mode.
2 The number of data points that is acquired is 16 MW. Therefore, if the display record length is 20 MW, only 8 divisions of
the waveform is displayed; if the display record length is 25 MW, only 6.4 divisions of the waveform is displayed.
In addition, the trigger positions in these cases are set by taking 8 divisions or 6.4 divisions as 100%.
3 Box average, averaging (simple average), and computation cannot be performed.
4 This record length cannot be specified on the 4 MW memory model.
