Memory division function can only be used with the Memory function.
Memory division settings are made on the Status screen - [Memory Div] sheet.
Blocks to be displayed can also be selected on the Waveform screen (p.136).

Opening the [Memory Div] sheet
Select [STATUS]
and then [Memory
Div] from the right-
click menu.
When using memory division, synchronization between blocks may not be possible in the following
conditions.
(MR8740 only)
When using memory division, the trigger output (TRIG_OUT terminal output) may output the Low
level or output erratically in the following conditions.
(MR8741 only)
• The time axis range is 5 s/div to 100 s/div
• The record (measurement) time is 5 ms or less
• Tracking wave display is [OFF].

• Waveforms can be recorded into individual blocks by dividing memory space into multiple blocks.
• You can record waveforms beginning at any block (Start Block), choose which blocks to display (Display
Block), or display multiple overlaid blocks (Reference Block).
• The maximum number of blocks for memory division depends on the installed memory board and recording
length (up to 1024 divisions).
• Triggered waveform data can be acquired continuously and recorded sequentially in specified blocks (at
the Start Block, for the specified Used Blocks). Dead time while displaying (during which triggers are
ignored) can be minimized.
• Even if the Memory Division function is not used, up to 16 blocks of data (depending on the specified
recording length) can be saved to each block, so that previously recorded data can be selected for display
on the Waveform Screen.
