• These sizes, which can be used only as a reference, of text les are acquired when analog channels (other
than Model MR8990 or Model U8991) are used. Any number of logic channels on one module occupies one
channel; one analog channel (Model MR8990 and Model U8991) occupies two channels each.
• The instrument divides les with a size that exceeds 512 MB into multiple les of about 512 MB each to save
them.

• These sizes, which can be used only as a reference, of text les are acquired when analog channels (other
than Model MR8990 or Model U8991) are used.
• Depending on the setting conditions, the size may slightly differ from those provided in the above table.
Allow 20% of the size provided in the above table for margin.
• The instrument divides les with a size that exceeds 512 MB into multiple les of about 512 MB each to save
them.
