5.6 Waveform Data
If the optional “MEMRECAM Waveform Input Software” (reference number: 584350-1) is used, it is
possible to input analog data (waveform data) during recording, and save the waveform data in files
(NWF). HXLink can display a graph of this NWF file or CSV file waveform data with an image. Also,
waveform data printing and CSV output is possible.
■ Open Waveform Data
The following three methods are available for opening waveform data files.
(1) Open a waveform file
(2) Open an image file and a waveform file simultaneously (automatic)
(3) Open an image file and a waveform data file not in the same folder simultaneously (manual)
・
Open a Waveform File Independently
Select “Open Other” from the “File” menu and specify a waveform file.
If opening a waveform file independently, none of the image display area is displayed.
・
Open an Image File and a Waveform File Simultaneously (Automatic)
When HXLink opens an image file and if there is a waveform file in the image file folder, the
image file and the waveform file are opened and displayed.
HXLink searches for a folder with the specified image file and opens the file with the extension
of nwf as a waveform data file. The file name for the searched waveform data file has the same
name as that of the image file, the same file name as the prefix of the image file name and has a
file name that includes _all on the files. NWF files with file names of _all indicate that all of the
recorded range has been saved.
The waveform input software that saves NWF files adds _all to the waveform file name if the
waveform data in the entire recorded range has been saved. Also, the waveform input software
adds _ as a prefix to the name of the downloaded camera image file if there are two or more
cameras recording.
Example)

An image file name containing _ (file name when recording with multiple cameras)
(The specified prefix when the waveform data file was saved was Sample)
Image file name
Waveform file name
Sample_file.mcf Sample.nwf or Sample_all.nwf

An image file name not containing _ (file name when recording with one camera)
Image file name
Waveform file name
file.mcf file.nwf or file_all.nwf
