ZC5890 type 10~40 channel high-power multi-channel loudspeaker life test equipment
Classification:
Key words:Electronic testing and measuring instruments
The ZC5890 series speaker power life test system is a professional equipment for speaker (or earphone) reliability test. The system has built-in stable multiple noise signal sources and digital filtering, and automatically calibrates and measures the output signal; the test is recorded regularly through a computer The current, voltage, impedance and power data can be used to analyze the performance of the speaker.
Model |
ZC5890 |
|
System Configuration |
External computer, independent display 1 signal source controller, 1 to 4 test controllers, power amplifiers are selected according to the number of channels and power |
|
