MEM File Size (Memory Function) 8861
File size (bytes) = settings size + data size
Calculation Method: "MEM Files" (⇒ p. A19)
When saving both Timebase 1 and Timebase 2, add both file sizes.
N
ote:Values in parentheses ( ) in the following table exceed 2 GB, and so cannot be saved unless size is reduced by parti
al
saving.

Refer to the Table for the data file size for Timebase 2 after acquiring Timebase 2 data quantity.
Calculating Timebase 2 data quantity:
Timebase 2 data quantity = Timebase 1 data quantity × ratio of timebases of Timebase 1 and Timebase 2
Ratio of Timebase 1 and Timebase 2: Timebase 1 / Timebase 2
Example. Recording Length = 100 div, Timebase 1 = 1 ms/div, and Timebase 2 = 100 ms/div:
Timebase 2 Data Quantity
= Timebase 1 data quantity (10000) × ratio of timebases of Timebase 1 and Timebase 2 (1 ms / 100 ms)
= 10000 × (1/100)
= 100
