Appendix 4 ASCII Data File Format
The format of the file that is produced when analog and logic signal data is saved in ASCII format is
indicated below.
Data
Header Size The number of header lines
Model Name The name of the instrument
Comment A comment attached at the time the data file was saved
BlockNumber The number of blocks for this group
The maximum block number when the number of blocks varies depending on the waveform
TraceName The names of each of the waveforms
BlockSize The number of data points in a single block of a waveform
VUnit Each waveform’s Y-axis unit (has no effect on the data)
Sample Rate The sample rate used for waveform acquisition
HResolution Each waveform’s X-axis conversion coefficient, HResolution
X-axis value = HResolution × (Data No. – 1) + HOffset
HOffset Each waveform’s X-axis conversion offset, HOffset
X-axis value = HResolution × (Data No. – 1) + HOffset
HUnit Each waveform’s X-axis unit (this has no effect on the data).
DisplayBlockSize The length of the data displayed on the screen (the display record length)
DisplayPointNo. This number shows what point in memory is on the leftmost side of the display record length
Date Date when waveform acquisition was completed
Time Time when waveform acquisition was completed
