SCD-108D-20
The SCD-108D-20 is an 8-channel plug-in signal conditioning card for use in Curtiss-Wright’s nDAU-26XX, CDAU-20XX, EDAU-20XX, and WDAU 20XX products. It is intended for applications requiring significant signal conditioning flexibility and simultaneous sampling capability.
The card provides constant voltage excitation on a four channel basis, programmable presample filtering, calibration and userprogrammable gain. The user may select between digitally implemented FIR and IIR filters. All filters are phase-locked to the channel format sample rate to maintain time correlation between the input signal and the PCM 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).
Alternatively, a filter with a user specified -3dB frequency that falls within limits calculated by TTCWare may be selected. The conditioned analog signal is digitized at up to 16-bit resolution for transmission in the system PCM output format.
The SCD-108D-20 has a superset of the functionality of all earlier SCD-108D cards. This card can be used in place of any of the earlier versions of the SCD-108D card.
