AD2502 Audio Analyzer with rich expansion card slots uch as DSIO, PDM, HDMI, BT DUO and digital interfaces

Lowest Cost Instrumentation for High Power Product Test

USD 5,700.00

AD2502 is a basic test instrument in the AD2000 series audio analyzer, which can be used as a professional R&D test or production line test. Maximum input voltage up to 230Vpk, bandwidth >90kHz. The biggest advantage of AD2502 is that it has very rich expansion card slots. In addition to the standard dual-channel analog output/input ports, it can also be equipped with various expansion modules such as DSIO, PDM, HDMI, BT DUO and digital interfaces.
