MC3242A is 4-channel data acquisition developed by BSWA TECH. It is a plug and play virtual instrument system, using the USB interface to connect the computer.

MC3242A was developed base on high performance data acquisition module. It includes 4 input channels and 2 output channels, can simultaneously analyze 4 channels of acoustic and vibration signals. It can apply to most acoustic and vibration testing with the VA-Lab measurement software.
