Description
Dimensions（unit：mm）
PM 6023 is an audio analyzer for acoustic testing on the production line. It tests speaker drivers, microphone units, and semi-finished speakers and microphones, and it reports the parameters that decide whether a unit ships: frequency response, sensitivity, distortion, impedance, phase and balance.
Eight analog input channels and three analog output channels sit in one chassis measuring 240 × 270 × 76.5 mm. Conversion is 24-bit in both directions and sampling runs from 1 kHz to 192 kHz, with the 20 Hz to 20 kHz band flat to within ±0.2 dB. Noise floor and distortion both stay below -90 dBV.
Two IEPE channels are built into the analog inputs and supply 24 V at 4 mA, so measurement microphones and accelerometers connect without external conditioning. Every output channel carries an 8 W amplifier, which is enough to drive a speaker load directly. A programmable supply module inside the instrument sets output voltage and resistance by command.
Interfaces are BNC and AUX, and the operating temperature range is 0 to 45 °C. PM 6023 works with MegaSig Stinger test software, and a device driver plus a dedicated DLL are supplied for automated stations.
