APx500 Audio Measurement Software Licensing FAQ


  • Q: Do I need to purchase APx500 audio measurement software?
  • A: Beginning with release 5.0, APx500 software must be purchased. Release 5.0 is included with the purchase of all new APx analyzers. Analyzers purchased in 2018 are entitled to a complimentary upgrade to release 5.0. Analyzers purchased in 2017 or earlier can purchase a license for 5.0 via their sales partner.

  • Q: When I buy a new instrument, does that include a software license?
  • A: Yes, new instruments include a license for the current release with no change in base instrument price. Version 5.0, which adds the ability to perform transfer function measurements, is the current release of APx500 audio measurement software, and is shipping with all new APx audio analyzers, whether B Series or Legacy. New units also include one year of software maintenance, licensing that instrument for APx version 6.0 when it is released, as well as any minor releases that occur between versions 5.0 and 6.0. Release 5.0 is compatible with all analyzers in the APx500 Series, however an APx KeyBox is required to run v5.0 on Legacy APx analyzers.

  • Q: I purchased an APx analyzer a month ago – do I still have to buy a license for 5.0?
  • A: Customers who purchased an APx analyzer in 2018 are entitled to a complimentary license for version 5.0 and should contact their AP sales representative. Options for extended software maintenance are also available.

  • Q: What is the difference between a software upgrade and a software maintenance contract?
  • A: A software upgrade purchases a license to upgrade a single APx analyzer to version 5.0 software. Adding a software maintenance contract to the upgrade authorizes that same analyzer for the next major release at a discount (compared to upgrading at the time of the next major release).

  • Q: Does this mean I have to pay for technical support too?
