CSV (Text) File Size (Recorder Function)
File size = header size + data size
Calculation method: "Recorder Function" ( p.A4)
Note:
When saving, CSV (text) files longer than 2
GB are segmented into files of 2 GB each.

*1: Header size = 30720 + 512(analog channel portion +Number of waveform calculation channels+Number of FFT cal-
culation channels + 1)
*2: the size of the time axis data = (analog channel portion + 2 xNumber of waveform calculation channels) x data (*4)
*3: the size of the mid-term data = (346 x Number of FFT points + 836) x Number of FFT calculation channels(*4)
(Depending on the measurement conditions, the file size may also increase or decrease from calculation formula result)
