Size of a file ＝ header + data
Size of a header ＝ 512×(15 ＋ number of analog channels ＋ number of logic
probes)
Size of a data＝ 2×number of analog channels×(recording length (DIV)×100＋1)
Saved channel number: When saving channels, each analog channel (up to 8) has a
corresponding logic channel, and such pairs are regarded as single channels.
(Example: Saving analog channels 1 and 2 also saves logic channels A and B, constituting a
saved channel number of 2.)
Relationship between saving analog and logic channels:
Regarding saving of 4, 8 or 16 analog channels in the above table, file sizes are calculated for
the case in which the analog channels have no corresponding logic channels.
Example: analog channels 9, 10, 11 and 12, and logic channels A through H are saved.
