AUDIO PRECISION APX515B Audio Analyzer
The Audio Precision APx515B Series is a high-performance audio analyzer optimized for production test. It is a best-in-class instrument for its combination of speed, performance, automation and ease-of-use. The Audio Precision APx515B can make all of the key audio measurements in less than three seconds. Despite its low cost, APx515 still has excellent performance, with a typical THD+N of €“106 dB, 1.2M point FFTs and up to 216k digital I/O, as well as the one-click automation and ease-of-use of all APx Series audio analyzers.
The B series APx515 operates either as a stand-alone test unit with its own user interface, or it can be controlled by a master .NET or LabVIEW application. In either case, an operator can control the APx515 with a keyboard, foot switch or barcode scanner, or the system can be totally automated. Switchers and external devices such as pass/fail lights are also supported. In stand-alone mode, sophisticated test sequences are created by selecting from a list of common audio measurements €”no coding required. On an automated manufacturing line, a master .NET or LabVIEW application can control the 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 user interface.
Specifications for the AUDIO PRECISION APX515B Audio Analyzer Include:
| Sine Frequency Range | 2.0 Hz to 80.1 kHz |
| Flatness (5 Hz - 20 kHz) | ±0.010 dB |
| Digital Output Sampling Rate | 27 kS/s - 200 kS/s |
| Residual Input Noise (20 kHz BW) | 1.4 µV |
