IQ File Converter is an Anritsu utility program for converting IQ Capture data files to and from several supported formats. IQ data can be captured on several Anritsu receivers. This allows a user to load captured IQ data into other applications and instruments. For instance, captured data converted to Anritsu’s VSG format, can be replayed on a BTS Master or Spectrum Master that have the VSG option installed. It is also useful to convert other Anritsu formats, or 3rd party pattern files into something that can be played back on a signal generator.
