Read Yokogawa *.wvf files

Reads Y-t data written by Yokogawa Oscilloscopes to binary *.wvf files

Description

Reads Y-t data from binary files written by Yokogawa DL1600 series, DL750 or 7440 oscilloscopes.
hdrread.m reads the information from the *.hdr header files.
wvfread.m reads the Y-t data from binary *.wvf files.

Probably, it also works for other Yokogawa oscilloscopes, but this has not been tested. Please let me know if it works or not with other models.

Thanks for writing this script; it works better than the Yokogawa equivalent!

Is there a way of reading History waveforms from a wvf file?

[Tristan Valenzuela]

Very helpfull. Thanks for the scripts!

Does anyone know how to read the data from a yokogawa .wdf file? I know that one can convert it to .hdr+.wvf with the yokogawa Xviewer... but doing it by hand on hundred of traces can be a real pain....
Thanks for your help any way!

This script is very helpful to me.

I've been using script for several projects now with Yokogawa DL1640 oscilloscope and also with Yokogawa SL1000 DAQ.

With SL1000 wdf files I convert them to wvf using it's own converter since your script does not support wdf files yet.

When I use this script in Linux I found that I have to change backslashes to slashes in both wvfread and hdrread files. Now I use isunix, ispc commands in matlab to correct this automatically. May be you can use fullfile command in matlab and omit slashes or backslashes completely!!

Thank you very much for sharing this!!!

Dear Tristan,

your question concerning YOKOGAWA *.wdf files: I recently found the follwing document: http://support.us.yokogawa.com/downloads/TMI/TM-DAQ/SL1000/Instruction%20Manuals/SL1000%20WDF%20API%20Specifications.pdf

It seems that the XViewer package contains DLLs, which in principle could be used from within Matlab for the purpose of reading wdf files (see Matlab external interfaces help for accessing DLL functions). It is not clear if the free/evaluation version of XViewer will provide the DLL, but there is a good chance. However, at the moment, I don't have enough time to dig into this.
