Advance Signal Analyzer(ASA)

ADVANCE SIGNAL ANALYZER (ASA) SIGNAL PROCESSOR WITH AUTOMATED SETUP AND OPERATION FOR SIZE AND VELOCITY
COMPANY : ARTIUM, U.S.A.

The ASA is the most advanced signal processor available for PDI applications. It is a Fourier transform based signal processor with several innovations to ensure optimum performance. The optical signal collected by the PDI optics is converted to a voltage using a PMT/pre-amplification system. The signal is then high-pass filtered and amplified before being fed to the ASA analog section. Within the analog section, the signal is mixed with a software selectable variable quadrature mixer. The quadrature mixer outputs are low-pass filtered to improve signal SNR. The quadrature outputs of the analog section are sampled and digitized at a software selectable sampling rate.

The digitized signal is then applied to the phase domain burst detector. The Phase Burst Detector (PBD) output is combined with the analog burst detector output and then used as an input to the adaptive sampling circuitry. The sampled data for each Doppler burst is then packed into a single data packet. The data packets are stamped with other relevant information (time of arrival, transit time and external input data) and transferred to the computer via a high-speed PCI interface card.

AUTOMATED INSTRUMENT MANAGEMENT SOFTWARE (AIMS) PACKAGE D WITH COORDINATE TRANSORMATIONS

The Artium Integrated Management Software (AIMS) controls all aspects of the instrument setup and operation. It can run either on Windows (2000/XP) or LINUX (2.4 kernel) operating systems. The system software is designed around a client/server model that allows remote operation via the intranet or the Internet and is multi-user accessible. Dedicated algorithms are included for automated setup of the instrument functions and online adjustment to the prevailing measurement conditions. An external input feature allows tagging of the LII signals with external events such as engine RPM or throttle. The software has the capability of accepting, processing, displaying, and storing data for extended periods of time without interruption. During long acquisition periods, the data can be broken into multiple files for greater manageability. The data analysis and display are easily extensible and may be modified as needed. The data can be easily exported to Microsoft Excel for analysis and plotting
