* 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
