Program creates a new trace with the larger number of points.
Note that the calling program is then responsible for transferring the file header information into the new trace. Interpolates single traces by taking the RFFT of the trace and zerofilling to a user selected power of 2. Due to the FFT, this can give some artifacts in the result if the trace baseline is not at zero. The interpolation Factor must be 2,4,8,16 or 32. The .ZIP file contains an .ABL and a .TST file.
