SCD-112D 12-Channel Signal Conditioning Card
The SCD-112D-2 is a 12-channel plug-in signal conditioning card for use in Curtiss-Wright’s EDAU-20XX, CDAU-20XX, and WDAU- 20XX products. The card is intended for applications that require significant signal conditioning flexibility and simultaneous sampling capability. The card provides constant voltage excitation on a perchannel basis, programmable presample filtering, calibration, and user-programmable 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 6th order Butterworth filter with a software-specified –3dB frequency falling within broad 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.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
