DAS Studio 3 software allows you to configure DAUs, network switches, recorders & ground stations in an integrated environment.
The KAD/ADC/135 is used to condition and digitize up to 12 differential-ended analog channels.
KAD/ADC/136 is used to condition & digitize up to 8 analog channels.
KAD/DSI/102 monitors the status of up to 24 differential ended discrete input channels. Each of these has an assigned programmable 32-bit counter.
The KAD/MAT/101 allows you to run your own programs based on a dual-core C6000DSP+ARM9 microcontroller. It provides high-performance DSP functions.
The KAD/VID/106 is an H.264 video encoder card that converts one of three composite analog video inputs.
KAD/ADC/120 12 channel Full-bridge ADC
The KAD/ADC/120 is used to condition and digitize up to twelve D/E analog channels.
At the heart of the KAD/ADC/120 is a hard-wired state machine that over-samples all channels at a rate between 48 ksps and 96 ksps and digitally filters any noise above the user-programmable cutoff frequency.
This is achieved using cascaded, half-band, Finite-Impulse-Response (FIR) filters followed by an 8th order Butterworth IIR filter with a default cutoff point set at one-quarter of the sampling frequency (fc = fs/4).
All signals are sampled simultaneously. Thus, when several channels are sampled at different sampling rates, at the start of an acquisition cycle all channels are aligned.
The KAD/ADC/120 is similar to the KAD/ADC/118 but does not support channel balancing. The KAD/ADC/120 is available with three different input ranges (±10V, ±1V, ±100mV). The input range must be specified when ordering.
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.
