APx KeyBox Request


The APx KeyBox is a hardware security module that must be mounted on any APx Series audio analyzer to enable APx500 v4.6 software. APx v4.6 will not operate (except in demo mode) without a properly authorized APx KeyBox mounted on the analyzer. Video: Introducing the APx KeyBox

Please use the form below to submit a request for an APx KeyBox.

Note: each APx KeyBox is instrument-specific. When placing a KeyBox request, you will need to include your analyzer’s serial number. An analyzer’s serial number can be found on the Calibration Label on the forward edge of the top cover. It can also be found on the Configuration Label (APx555, 52x, 58x) or Serial Number Label (APx511, 515) on the rear of the instrument.

Each KeyBox is provided free-of-charge. Questions? Please see the APx KeyBox FAQ.
