Appendix 3 ASCII Data File Format
The instrument can save waveform data to ASCII files. The format of such files is given below.
Data
Header Size The number of header lines.
Model Name The model name.
Comment Comment attached at the time the data file was saved.
BlockNumber Block number for this group.
When the block numbers vary depending on the waveform, this is the maximum block
number.
TraceName Name of each waveform.
BlockSize The number of data points in one block for each waveform.
VUnit Each waveform's Y-axis unit (this has no effect on the data).
SampleRate The sample rate at the time of 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 coefficient, 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 displayed on the left-most side of the
display record length.
Date Date when waveform acquisition completed.
Time Time when waveform acquisition completed.
