DAS Studio 3 software allows you to configure DAUs, network switches, recorders & ground stations in an integrated environment.
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.
The KAM/CHS/03F is a compact three-user-slot KAM-500 chassis, which along with the housing and backplane, includes a KAM/PSU/008 power supply unit.
The KAM/CHS/04L is a compact four user-slot KAM-500 chassis, which along with the housing and backplane, includes a KAM/PSU/006 power supply unit.
The NET/SWI/101 is an 8-port airborne Ethernet switch designed for operating in harsh environments. Each port is configurable for 10BaseT, 100BaseTX, and 1000BaseT link speeds or auto-negotiate over copper wiring, supporting straight-through or cross-over cables.
KAD/ADC/116 12 channel Accelerometer ADC
The KAD/ADC/116 is used to condition and digitize up to 12 accelerometer-type input channels. Each of these channels has a constant current source and AC coupled (DC-reject) inputs for use with integrated charge-amp piezoelectric accelerometer devices.
At the heart of the KAD/ADC/116 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. This means that even when several channels are sampled at different sampling rates, the sample at the start of the acquisition will always be synchronized.
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.
