Offers impedance response and current measurements of a connected speaker or resistive load (25 mA to 10 A).
The 1/2 cycle PDM interface box converts simultaneously the digital output signal of 8 digital MEMS microphones into individual analog audio channels. This accessory applies for applications with parallel testing of 8 MEMS microphones in an EOL production environment.
The operation is controlled via USB from an external host computer. The PDM interface box provides 0 dBFS reference output signal for calibration and direct connections to digital I/O interfaces. The microphone supply voltage is adjustable. The Left/Right configuration of the microphone is controlled by the PC and the presence of any connected microphone indicated by LED's.
Due to its small size, the PDM interface box can be located near the microphones under test, thus ensuring reliable operation with the short digital interface lines.
