How to convert log data recorded by logging software (MAS 510) to CSV file.


Logging software is PC application software for controlling spectrum analyzer (MSA 500 series) by PC via USB communication and recording spectral data for a long time. It is ideal for monitoring abnormal signals during day and night, disturbances, interfering radio waves, and for long-term unattended data recording. The log (spectral) data is recorded in binary format and can be used in Excel and other tools by converting it to CSV file.

      The CSV file is largely divided into a measurement condition part and a waveform data part.

    • CF : Center frequency
      SPAN : Frequency span
      REF : Reference level
      SWP : Sweep time
      DET : Detection mode
      RBW : Resolution bandwidth
      VBW : Video bandwidth
      SCALE : Display scale
      LmtLv : Limit level
      TRACE : Spectral data points
