Creation of ASCII Header Files
When waveform data are saved to the floppy disk, the following two files are
automatically created in the same directory.
• Waveform data file (
∗
.WVF)
• ASCII header file (
∗
.HDR)
Of the two files, only the waveform data file can be loaded by the instrument (However,
the ASCII header file (.HDR) must also exist). The ASCII header file that is being
described in this section cannot be opened with the instrument. This file can be used
when analyzing waveforms on a PC, for example.
*1 Endian mode when the file was saved
Big : Motorola 68000 series data
*2 Storage format of the waveform data of the BINARY file
Trace : Format in which blocks are organized for each waveform
*3 Start position of the waveform data of the BINARY file
The offset from the beginning of the file. This value is always 0 for the PZ4000.
*4 Maximum number of blocks of a group
When the number of blocks varies for each waveform, this number is the maximum
number of blocks. This value is always 1 for the PZ4000.
*5 Y-axis converting equation of each waveform
Y-axis value = VResolution
×
raw data + VOffset
*6 Data Type
ISn : n-byte signed integer
IUn : n-byte unsigned integer
FSn : n-byte signed real number
FUn : n-byte unsigned real number
Bm : m-bit data
*7 X-axis converting equation of each waveform
X-axis value = HResolution
×
raw data + HOffset
