This data was indeed captured from an oscilloscope. This oscilloscope only offers two file formats for saving data. *.csv and *.isf. The ISF is a binary based format used by the manufacture (Tektronix). Its file structure is:
:WFMPRE:BYT_NR 2;BIT_NR 16;ENCDG BIN;BN_FMT RI;BYT_OR MSB;NR_PT 10000;WFID "Ch1, DC coupling, 2.0E0 V/div, 1.0E-5 s/div, 10000 points, Sample mode";PT_FMT Y;XINCR 1.0E-8;PT_OFF 0;XZERO 3.5E-4;XUNIT "s";YMULT 3.125E-4;YZERO 0.0E0;YOFF 0.0E0;YUNIT "V";:CURVE #520000<binary data>
I will need to investigate / test this format to see if compatible with the FileTools[Binary] function and get back to you. I assume the header information will also need stripped based on the help page.
Thank you for the suggestion,
