Concurrent SIGnal Workbench products provide flexible, programmable signal conditioning solutions for a wide range of data acquisition applications. SIGnal Workbench is ideal for hardware-in-the-loop test stands and dynamic data processing and monitoring systems for engines and machinery.
SIGnal Workbench is a complete solution that can provide everything needed for high-cycle testing – real-time computer system, data acquisition I/O cards, programmable signal conditioning, cabling and powerful GUI test software for data acquisition control, management, display and post-test analysis. SIGnal Workbench's programmable signal conditioning hardware is available separately with a control API for real-time applications that require analog input conditioning.
SIGnal Workbench features individual-programmable signal conditioning modules that provide four channels of configurable transducer interface circuitry on a 3U euro-card. Each channel provides a programmable current/voltage output source and a fault-protected programmable gain amplifier. Selecting the voltage source mode allows the module to be configured as a strain conditioner. All of the functionality required to condition signals from sensors that use ¼, ½ or full bridge transducer configurations are supported in this mode.
SIGnal Workbench also offers 3U 4-channel thermocouple signal conditioning card with type J and K miniature PCC connectors. Each connector has individually-monitored cold junction temperatures. Other thermocouple connector types are available upon request.
Selecting the current source mode allows the module to support transducers that require constant current excitation, such as integrated electronics piezoelectric (IEPE) transducers. Channels can also be configured as instrumentation amplifiers to monitor general-purpose analog input signals. Conditioned signals are driven out of the module by low-impedance, high-speed operational amplifiers. All current and voltage sources are programmable via easy-to-use graphical interface.
Three shrouded headers on the backplane of a signal conditioning chassis are used to terminate the input and output signals for each module. The first two headers terminate the four input signal connections. The third connecter provides the buffered output signals. Outputs can be connected to the high-impedance differential input of SIGnal Workbench’s analog input cards to provide a complete signal conditioning and A-to-D conversion solution. All output is routed through the real panel of the signal conditioning chassis. Chassis that accommodate 8 and 16 signal conditioning modules are available.
SIGnal Workbench solutions are available with Concurrent iHawk™ multiprocessing platforms running the RedHawk™ Linux® real-time operating system. SIGnal Workbench platforms are custom-configured to meet the needs of your test application. Storage, memory size and processor performance can be selected in accordance with test run durations and channel count requirements. RedHawk provides the fully deterministic performance needed in high-performance, time-critical test applications.
SIGnal Workbench systems feature one or more 32-channel, 24-bit Sigma-Delta analog input boards supporting a rate of 200 Ksamples per second per channel. Other simultaneous sampling PCI and PCIe analog input cards are also available. The iHawk computer system, signal conditioning chassis and cabling can be optionally mounted in a 14U or 34U rackmount cabinet.
SIGnal Workbench solutions are available with EDAS-DS software. EDAS-DS is a state-of-the-art, real-time, dynamic data acquisition and monitoring environment developed to meet the requirements of modern gas turbine R&D, engine production and engine overhaul test facilities. With EDAS-DS, SIGnal Workbench is a complete turn-key solution for acquiring, storing and processing dynamic data signals.
EDAS-DS built-in real-time monitoring features allow users to choose from any number of frequency domain and/or time domain engineering plots in real time and plot vibration channels against performance parameters with no limit on number of plots and no performance impact. EDAS-DS also offers remote monitoring. With this option, users have the ability to monitor test data on any number of real-time displays either at the test facility or a remote location.
With its simplified user interface, EDAS-DS allows a single user to control all aspects of testing, while its data viewer replays data exactly as it was recorded or as desired by the analyst. EDAS-DS not only provides exceptional value for users, but also facilitates convenient sharing of data with development partners or among project participants without additional investment. Benefits of EDAS-DS include reduced testing time, lower test costs, comprehensive real-time monitoring, minimized re-testing, reduced risk to test articles and multi-channel digital calibration for faster test set up.
