The MSCD-108D is an 8-channel plugin signal-conditioning module for use in Curtiss-Wright’s miniature, stackable data acquisition products. The module is intended for applications that require high channel density, significant signal conditioning flexibility and/or simultaneous sampling capability. The module provides DC input coupling, constant voltage excitation, programmable pre-sample digital filtering, calibration, and user-programmable gain and offset. FIR or IIR digital pre-sample filtering may be selected on a per-channel basis. Each digital filter is phase locked to the channel format sample rate to maintain time correlation between the input signal and the data output. The filter can be set for 3, 4, 5, 6, 8, or 10 times oversampling (the filter -3dB point will be automatically set to the format sampling rate divided by the oversampling value). The conditioned analog signal is digitized at up to 16-bit resolution for transmission in the system data output format.
