Waveform File Size Calculation Method____________________________
MEM File
File size (bytes) = setting size
*1
+ data size
*2
*1: Setting size =23552 + 512 (analog channel portion + 4 x logic channel portion +Number of waveform calculation
channels )
*2: Data size = 2 x (analog channel portion+logic channel portion + 2 xNumber of waveform calculation channels) x num-
ber of data
REC File
File size (bytes) = setting size
*1
+ data size
*2
*1: Setting size = 23552 + 512 (analog channel portion + 4 x logic channel portion)
*2: Data size = 4 x (analog channel portion+logic channel portion ) x number of data
FFT File
File size (bytes) =header size
*1
+ the size of the time axis data
*2
+ the size of the mid-term data
*3
*1: Header size = 25600 + 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)
XYC File
File size (bytes) = header size
*1
+ data size
*2
*1: Header size = 24576 + 512 (analog channel portion)
*2: Data size = 2 x saved analog channel portion x number of data
CSV (Text) File
Memory Function
File size (bytes) = header size
*1
+ data size
*2
*1: Header size = 194 + 103 x (saved analog channels + saved logic channels)
*2: Data size = (18 + 14 x saved analog channels + 2 x logic channels) x number of data
Recorder Function
File size (bytes) = header size
*1
+ data size
*2
*1: Header size = 194 + 130 x (saved analog channels + saved logic channels)
*2: Data size = (18 + 28 x saved analog channels + 4 x logic channels) x number of data
