Make the Switch from R&S to Audio Precision

All R&S audio analyzer products have been discontinued with no replacements on the horizon. Five Reasons to switch from Rohde & Schwarz audio analyzers to an APx500:

1. Audio Precision is the standard in audio test and measurement. We have been building and supporting our products since 1984, longer than any other company. We continue to actively develop our products and provide 2 or more updates every year.

2. For every discontinued Rohde & Schwarz audio analyzer product we offer a functionally equivalent analyzer with either superior performance, lower cost, or both.

3. Every Audio Precision analyzer is delivered with ISO 17025, A2LA accredited calibration, exceeding the calibration standard with which UPV and UPP analyzers where shipped.

4. We support 3rd party control and automation via LabVIEW, MATLAB, C#, Visual Basic, Python and Microsoft .NET.

5. Audio Precision has live, factory trained technical support available in North America, Europe, and Asia. Service and calibration are available in all those regions. Our engineers are ready to help migrate your application from legacy, unsupported equipment to a state of the art, actively supported audio measurement platform.
