Production Analyzer - Hardware of KLIPPEL QC SYSTEM
- 2 balanced XLR inputs + outputs (100 dB SNR)
- 2 BNC microphone inputs (100 dB SNR)
- input preamplifiers controlled in 1dB steps to ensure maximal SNR
- IEPE power for microphone, accelerometers and others
- 2 speaker terminals to measure two channels simultaneously
- Galvanically decoupled current sensor for up to 40 A (15 V rms continuous operation)
- Voltage sensor up to 200 V (4 wire Kelvin configuration)
- Interface for temperature and humidity sensor for climate monitoring
- General purpose digital input and output pins (GPIO)
- Gain and performance check of external power amplifier
The Production Analyzer is the sensor and data acquisition platform for the KLIPPEL QC software. It comprises a dedicated sensor front-end for speaker measurements as well as for professional AD/DA converter. The PA is equipped with built-in current and voltage sensors, provides a microphone power supply, symmetrical in- and outputs and digital I/O. It allows performing highly flexible tests on electro-acoustical transducers. It is a two-channel system which allows the measurement of two speakers under test in parallel or one driver while mounting the second driver in time critical applications, such as end-of-line testing.
