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

Waveform File Size Calculation Method
MEM File
File size (bytes) = setting size
*1
+ data size
*2
*1: (Setting size) =28672 + 512 × [(number of analog channels) + 4 × (number of logic units) + (number of
waveform calculation channels)]
*2: (Data size) = 2 × [(number of analog channels) + (number of logic units) + 2 × (number of waveform calculation
channels)] × (number of data)
REC File
File size (bytes) = setting size
*1
+ data size
*2
*1: (Setting size) = 28672 + 512 × [(number of analog ch 4 × (number of logic units)]
*2: (Data size) = 4 × [(number of analog channels) + (number of logic units)] × (number of data)
FFT File
File size (bytes) =header size
*1 + size of time axis data *2 + size of mid-term data *3
*1: (Header size) = 30720 + 512 × [(number of analog channels) + (number of waveform calculation channels) +
(number of FFT calculation channels) + 1]
*2: (Size of time axis data) = [(number of analog channels) + 2 × (number of waveform calculation channels)] ×
(number of data) (*4)
*3: (Size of mid-term data) = [346 × (number of FFT points) + 836] × (number of FFT calculation channels) (*4)
(Depending on the measurement conditions, the file size may also increase or decrease from calculation formula
results)
XYC File
File size (bytes) = header size
*1
+ data size
*2
*1: (Header size) = 24576 + 512 × (number of analog channels)
*2: (Data size) = 2 × (number of saved analog channels) × (number of data)
CSV (Text) File
Memory Function
File size (bytes) = header size
*1 + data size *2
*1: (Header size) = 194 + 103 × [(number of saved analog channels) + number of saved logic channels)]
*2: (Data size) = [18 + 14 × (number of saved analog channels) + 2 × (number of logic channels)] × (number of
data)
Recorder Function
File size (bytes) = header size
*1
+ data size
*2
*1: (Header size) = 194 + 130 × [(number of saved analog channels) + (number of saved logic channels)]
*2: (Data size) = [18 + 28 × (number of saved analog channels) + 4 × (number of logic channels)] × (number of
data)
