What is the native file format for the AWG2000 series?

The file format for the AWG2000 series is proprietary. It is part of a purchased operating system and we are not allowed, by license, to divulge the format. However, we have a large collection of utilities that will convert ASCII (Y values only) or Comma Separated Values (X and Y pairs) files into the AWG2000 series file format. These utilities operate in a DOS environment and can be used on an IBM compatible PC running DOS, or Windows that support running DOS programs.

Also there is a Windows utility called ArbExpress which will allow you to create and edit AWG2021 and AWG2005 .wfm waveform files.
