Saving and Loading Data
• Saving the Waveform Display Data
Select Wave from the File Item menu to save waveform display data.
• Relationship between the Waveform Display Data That Can Be Saved and
Measurement Modes
There are limitations on waveform display data that can be saved depending on the
measurement mode as indicated below: Set the item to be saved to waveform
sampling data (Acquisition) for FFT waveforms.

*1 Applicable only to products with the motor evaluation function (motor version).
*2 Applicable only to products with the advanced computation (/G6 option).
• Selecting the Data Type
Select the data type from below. The extension is automatically added.
•Binary
• The following two files are created in the directory.
• Waveform display data file (.wvf)
• ASCII header file (.hdr)
• Waveform display data is saved in binary format.
• For details on the ASCII header file, see appendix 3.
• Either file cannot be loaded into the WT3000.
• ASCII
• Saved in ASCII format.
• The file can be used on your PC for analysis.
• The file cannot be loaded into the WT3000.
• Float
• Saved in 32-bit floating format.
• The file cannot be loaded into the WT3000.
Note
The waveform display data that is saved on the WT3000 is not the sampled data acquired at
the sample rate (approximately 200 kS/s) of the WT3000. The waveform display data is
waveform sampling data that has been P-P compressed (see the note in section 2.7) to a set
of 1002 data points for displaying the waveform on the screen. Waveform sampling data can
be saved in waveform computation mode or FFT mode on models with the advanced
computation (/G6) option.
