Keysight DAQM909A: 4-Channel Simultaneous Sampling Digitizer Module

The DAQM909A is a four-channel digitizer module capable of providing four simultaneously-sampled channels with sampling rate as high as 800k samples per second with a maximum resolution of 24 bits. The input channels of the DAQM909A can be configured as a differential input or a single-ended input and each of the channels can provide up to 4mA of constant current to power up an external IEPE transducer.

When three DAQM909A modules are inserted within the same instrument, all 12 channels can be synchronized to provide simultaneous sampling.
