COT’S PICKS Kaman KD-5600 Family of Digital Differential Measuring Systems Ideal for Wide Range of Applications
The Measuring Division of Kaman Precision Products, Inc., announces that the KD-5600 family of digital eddy current measurement systems are ideal for use in COTS applications for fast steering mirrors, magnetic bearing active control, shaft vibration, image stabilization, and adaptive optics. Customers in the small satellite, semi-conductors, military/aerospace, high precision metalworking, and UAV/drone sectors benefit from the KD-5600 system’s host of features. Designed for non-contact linear position displacement sensing applications, Kaman released two configurations for tailored use. The KD5656 (Full System) and KD-5690 FE (Front-End) are equipped with custom sensors, signal processing, analog to digital converter, and a custom calibration system to ensure precision and accuracy. For optimum operation for each channel,
Acromag Releases the Smallest Mezzanine Module with the Power of a Zynq® UltraScale+™ MPSoC for I/O Processing and Programmable Logic This new AcroPack® module combines multicore ARM processors, FPGA capabilities, and I/O interfaces on a rugged, high-density platform for embedded computing applications Acromag’s new APZU series expands their offering of mini PCIe-based AcroPack modules with a programmable I/O solution featuring the Xilinx® Zynq UltraScale+ multiprocessor systemon-a-chip (MPSoC). Three models are available offering a choice of digital I/O interfaces with 28 TTL, 20 TTL, and 3 RS422/485, or 14 LVDS signals. These mezzanine modules mount on a variety of AcroPack carrier cards for PCIe, VPX, and other platforms allowing developers to mix and match I/O combinations on a single board for embedded applications running on Linux®, Windows®, or VxWorks® operating systems. The APZU’s Zynq 3CG MPSoC combines a feature-rich ARM-based processing system and programmable logic in a single device. Two dual-core ARM Cortex CPUs (A53 application processor and R5 real-time processor) deliver high-performance 26

the KD-5600 system has two matched sensors. Input signals are filtered and SWaP-C scaled to provide optimum operation, remove common mode noise, and deliver a drive signal. They also provide digital filtering as part of the signal conditioning to reduce signal noise. The suite of products is designed with high resolution, bandwidth, and linearity and equipped with a Serial Peripheral Interface Bus for fast data transfers and no firmware. Additionally, the KD-5600 system samples data at eight times the standard data rate. Oversampling at high volume provides higher resolution at the defined data rate, which results in a signal resolution that is eight times better than a system sampling at the Nyquist rate. Using a 9D connector for reading data, power, and control signals, the system operates from a single power supply with a voltage range of 8-28 volts. These features combined ensure long-term stability. Kaman Precision Products, Inc. www.kamansensors.com
computation capability. 154k logic cells provide plenty of FPGA processing blocks for hardware acceleration and compute-intensive tasks. Additional resources include large on-chip memory, external memory interfaces, and a rich set of peripheral connectivity interfaces. Gigabit Ethernet, USB 2.0, and USB-UART interfaces are supported. AcroPack modules are only 30mm x 70mm. They use a standard mini PCIe edge connector but add a down-facing 100-pin connector which internally routes I/O signals through the carrier card to secure field connectors, thus eliminating loose cables and increasing reliability. More information about the AcroPack series is available from Acromag’s website at www.Acromag.com/AcroPacks. “Designers can increase overall system per-
formance by leveraging the tightly-coupled CPU and FPGA computing engines for different signal processing tasks in a very small and cost-effective form factor,” stated Robert Greenfield, Acromag’s Business Development Manager. Designed for defense and aerospace systems, these AcroPacks are ideal for adaptive filtering, protocol conversion, simulation, HIL test, motor control, image processing, and sensor fusion applications. The COTS modules can be used in PCIe servers, VPX or CompactPCI Serial chassis, and small form factor embedded computers. Acromag www.acromag.com
