AUDIO PRECISION APX515 Audio Analyzer
The Audio Precision APx515 is a high performance audio analyzer optimized for production test. It is a best-in-class instrument for its speed, performance, automation and ease-of-use. It has excellent performance, with a typical THD+N of €“106 dB, 1M point FFTs and 192k digital I/O, as well as the one-click automation and ease-of-use of all APx Series audio analyzers. In stand-alone mode, sophisticated test sequences are created by selecting from a list of common audio measurements €”no coding required. Pass/fail limits, advanced configurations and user prompts can be added as necessary, then the type of report is selected: rich graphic printouts using Microsoft Word or export to CSV.
On an automated line, a master .NET or LabVIEW application can control the Audio Precision APx515 directly using the API or APx LabVIEW driver. Individual measurements can be made or the master application can call a test sequence created with the APx UI. all APx515 audio analyzers use the same software, making tests and results easier to share between vendors, R&D and production facilities anywhere in the world. The Audio Precision APx515 can make all of the key audio measurements in less than three seconds.
Specifications for the AUDIO PRECISION APX515 Audio Analyzer Include:
| Residual THD+N (20 kHz BW) | €“102 dB + 1.4 µV Typical < €“106 dB |
| Sine Frequency Range | 2 Hz to 80.1 kHz |
| Maximum Amplitude (balanced) | 16.00Vrms |
| Digital Output Sampling Rate | 22 kHz €“192 kHz |
