The maximum available recording time depends on the selected timebase.
The maximum recording time can be obtained by the following formula.
Refer to the following tables for the information about recordable time.
(d: days/ h: hours/ min: minutes/ s: seconds)
Appendix 2.3 Timebase and Maximum Recordable
Time
Recordable time can be verified on the Status
screen - [Status] sheet. ([Recording period])
Recordable Time = Timebase x Recording Length
Setting a slow timebase may result in a very long recording time (over a year)
which may exceed the guarantee period or product life, in which case we cannot
guarantee operation.

*: Also when recording length is set to [Cont.], the the maximum recording length is 80,000div.
The maximum record length is automatically determined by settings for the number of channels
used and the number of divisions.
