The MnACQ-2700 is a dual gigabit (1000BASE-T) port miniature networked data acquisition and encoding unit that supports simultaneous bulk and selected data into multiple industry standard formats.
The ADAU-2016 is a 16 user-slot Axon chassis, which along with the housing and backplane, includes an isolated 100W power supply for the controller and user modules.
IADS RTStation is a complete real-time and post-test display and analysis software suite and is scalable from a laptop to a large workgroup through its client/server software architecture.
The nREC-7000 is a high-speed network recorder for use with flight test data acquisition and multiplexing units, recording on two 10GBASE-SR ports and two 1000BASE-T ports.
The TTS-9800-2 series multiband, multimode transmitter provides the user with state-of-the-art modulation, forward error correction, and space-time processing compatibility to IRIG-106-15.
The TTC NSW-12GT is a rugged 12-port Ethernet switch that enables multicast data to be accurately distributed between nodes with precise timing.
MFED-208A Frequency/Event/Discrete Conditioner Module
The MFED-208A-1 is a frequency, event, discrete input module designed for use in Curtiss-Wright’s miniature series of programmable data acquisition units (MPDAU-2000). The MFED-208A-1 provides concurrent frequency and period measurements of a given analog or digital input signal. These measurements are provided in the PCM format with multiple formats including IEEE-754 half and single precision data. The MFED-208A-1 also provides a totalizer function that counts positive zero crossings and can be reset via dedicated hardware pins (external reset) or by reading the channel in the PCM format (reset on read). In addition, discrete bi-level digital event inputs are provided with the option to time tag any event input using system time from the host stack or via an internal counter if system time is not available.
Additional Features
- Up to four time-tagged events available for any combination of channels
- Options for both floating-point (IEEE 754) and fixed-point data output formats
- Totalizer back-up available through power loss/ brownouts
- Compatible with Curtiss-Wright’s miniature data acquisition products
- Programmed with TTCWare
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.
