I am trying to open a data file (.trc) recorded by high speed scilloscope, but got error when using read binary as below.

May you give any suggetsion, thanks.

 End of file encountered.

Do you know the format of the binary file?  Is it 32 bit, 16 bit, something else?  Is there any header information at the beginning of the file?  Do you know how many records are present?
