4 EDM (Engineering Data Management) Selection Guide EDM Working Modes EDM is the PC software that supports hardware platforms of CoCo-80/90 and Spider with post processing functions. EDM has four working modes: CoCo-80 DSA mode: accesses CoCo-80 in its DSA mode, download files and view data files. CSA Editor, a tool of editing CoCo testing projects, will be included in this mode. CoCo-80 VDC mode: creates route data collection database, upload settings to CoCo, download data to PC, trending and alarm analysis. There are two versions of VDC modes: personal version allows the user access the database on his local PC. Enterprise version allows multiple user access the database on the LAN. Spider Real-Time Mode: operates on Spider hardware in real-time Post Analysis Mode: analyzes the data files on PC using various algorithms. PA has three versions: PA Viewer allows the user to view the data and create report; PA Basic has FFT spectral analysis and 3D signal display functions; PA Premium has all post analysis functions. The basic structure of EDM software is: EDM (Engineering Data Management) CoCo-80 DSA Mode, with or without CSA Editor CoCo-80 VDC Mode VDC Personal Spider Real Time Mode VDC Enterprise Post Analysis Mode PA Viewer PA Basic PA Premium EDM software is registered to a CoCo or a Spider device. To activate the EDM software, the user must have a License Key. 4

5 EDM Post Analysis (PA) Functions EDM PA is one of the working modes. There are three versions of Post Analysis functions, PA Viewer, PA Basic and PA Premium. The function comparison is listed below: Functions PA Viewer PA Basic PA Premium Browse, display and edit long waveform files Signal display with different spectrum unit and X-Y scale Signal annotation, cursor, play sound, calculate RMS, THD, ZOOM-in, ZOOM-out, auto scaling Create template-based report in HTML, Excel, Word or PDF Engineering unit conversion, db reference Export to standard formats including ASAM-ODS, UFF, BUFF, MATLAB, TDM, user-defined ASCII and wave files Import user-defined ASCII file, wave file, Pacific Instrument file Acceleration, velocity and displacement conversion FFT Spectral analysis: FFT, auto power spectra, cross power spectra, frequency response function 3D display: waterfall, color map Math Functions: abs, +, -, *, /, square, square-root, log, integration, differentiation, RMS, peak, offset and scale, Digital Filters: IIR, FIR, Low-pass, High-pass, Bandpass User defined data conditioning modules Fractional octave filters: 1/1, 1/3, 1/6, 1/12 Order Tracking: RPM spectra, order spectra Polynomial Curve Fit Data file batch processing EDM Technology and PC Requirements The EDM software is a PC desktop application developed using Microsoft.NET technology. It runs on Windows XP/SP2 or Windows Vista (32 bit and 64 bit versions supported). EDM reporting function requires Office 2000 or later installed on the same PC. When communicating with the CoCo using an Ethernet or wireless connection, the PC must be configured with TCP/IP network protocol. When communicating with the CoCo using a USB port, the PC must have the CoCo USB device driver installed. In order to support the VDC mode, a MySQL database server must be installed on the PC. If you only intend to run the DSA mode, MySQL is not needed. The EDM software design, style and layout are similar to Office Large icons on the ribbon and customizable color scheme make the EDM user interface easy to access and operate. There are four main tab pages in the EDM main window: Home, View, Analysis and Report. The Home tab page shows the content on the CoCo device and the local file folder. The View tab shows stored files and signals. The Analysis tab, which 5

6 is only available in the EDM premium version, shows the post-processing setup; the Report tab displays the reports generated by the EDM. EDM General Functions Signal Display Signals are displayed in a Signal Tab Signal Window Signal Pane hierarchy. Multiple signal tabs can be opened.

Using the analysis tab, the user can create and edit computed signal. These signals will be displayed in the Tree View under the Computed Signal group. These data files can be viewed or reported like other signals. The configuration containing the analysis functions and parameters applied to data file is called Analysis Profile. A control panel is available to control and display the process of Post Analysis. Basic Signal Conditioning Modules Math Functions: abs, +, -, *, /, square, square-root, log, integration with low-pass, integration with high-pass, double integration with low-pass, double integration with high-pass, differentiation, double differentiation RMS: apply RMS estimation to an input data stream and generate a continuous output stream Peak: extract the peak or peak-peak value over a period of time and generate the time stream 12

13 Offset Scale: apply a multiplier gain and offset to any input data stream and generate the output stream continuously Acceleration, Velocity and Displacement Math Conversions for Time Streams: acceleration to velocity, acceleration to displacement, velocity to displacement High-Pass Filters: user-defined cutoff frequency to filter out the DC and low frequency to remove the drift effect Digital Filter Modules Digital filters are CSA modules that are applied in the data conditioning phase. The user can cascade digital filters or other data conditioning modules to construct powerful real-time analysis functions. There are mainly three models of real-time digital filters: Decimation filter, FIR filter and IIR Filter. According to his or her criteria, the user designs the filter model with a graphic design tool provided in the CSA Editor and uses the filter design parameters for execution. The graphic design tool draws the filter performance in vertical axis with db unit and horizontal axis in relative frequency. Filter Design Display: the user enters the cutoff frequencies, criteria of attenuation, ripple and filter orders. The design tool provides the frequency response of the filter in graphic format. Decimation Filter: 2:1 decimation with built in anti-aliasing filter. Anti-aliasing attenuation is more than -80dB which provides sufficient removal for high frequency noise. User sets decimation stages. Each stage decimates data to half. FIR Filter Using Window Method: FIR filter designed based on data window applied to the sinc function. Data window types: Hanning, Hamming, Flattop, Uniform, Kaiser-Bessel, Blackman. The user selects one of low-pass, high-pass, band-pass or band-stop types; sets one or two cutoff frequencies either relative to sampling rate or in fixed value; and sets the filter length between 11 and 127 (number of FIR taps). FIR Filter Using Remez Method: The Remez FIR Filter design block implements the Parks-McClellan algorithm to design and apply a linear-phase filter with an arbitrary multiband magnitude response. The user selects low-pass, high-pass, band-pass or band-stop types; sets one or two cutoff frequencies either relative to sampling rate or in fixed value; and sets the filter length between 11 and 127 (number of FIR taps). IIR Filters (3 types): Butterworth, Chebyshev I, Elliptic: the user selects one of the filter types above, selects low-pass, high-pass, band-pass or band-stop types; sets one or two cutoff frequencies either relative to sampling rate or in fixed value; and sets the filter order between 1 to 20. FFT Spectral Analysis Support all the data conditioning operations in basic signal conditioning template. FFT, auto power spectra, cross power spectra, frequency response function is also available on the output time stream from data conditioning operation. Support Acquisition Mode: Free Run, Continuous after Trigger, Single Shot with Trigger, Single Shot without Trigger, Auto-Arm Trigger, Manual-Arm Trigger Octave Filters Supports all the data conditioning operations listed in basic signal conditioning template.

Order Tracking Supports all the data conditioning operations listed in basic signal conditioning template. Order Tracking Analysis can be applied to the output time stream from data conditioning operation. A precise tachometer processing computation will be applied to tachometer input time stream to generate an RPM result. The following measurements can be made for user selection: RPM spectrum, fixed band RPM spectra, order tracks, and order spectra. RPM Spectrum and Fixed Band RPM Spectra FFT Block Sizes: 128 to 65,536 Acquisition Mode: free run, run up, run down, run up and down, run down and up Fixed Band RPM spectra: user definable band range. Instrument calculates the total power within the fixed band versus RPM (Spectrum Units: EU rms, EU rms 2 ). Order Tracks and Order Spectra Order Spectrum are 3D signals with auto power spectrum normalized to orders and changing with RPM. Order Tracks are frequency amplitude signals extracted from 3D Order Spectrum with a fixed order. Delta Order of Order Spectrum: to 1 Acquisition Mode: free run, run up, run down, run up and down, run down and Uup Order Spectrum View Mode: 2 dimensional, waterfall or spectrogram (RPM as x-axis) Curve Fit Use least-mean-square (LMS) criteria to create polynomial formula that approximates the Frequency Response Functions. Maximum Orders: 20 poles, 20 zeros Frequency Scale of FRF Signals: linear or logarithmic frequency scaling Curve Model Display: in pole/zero or polynomial formats, instantly compare with the original FRF signals. Synthesis: Curve fit allows the user to change the gain, delay and frequency scale, set pole and zero locations to synthesize the FRF signals. Analysis Profile Operation Create Analysis Profile: create certain types of analysis profile for data files containing time domain signals. Export/Import Analysis Profile: export Analysis Profile to file to later import and apply same analysis for other data file. Copy/Paste Analysis Profile: for recorded files listed in Tree View, the export/import analysis profile operation can be implemented using the copy/paste operation on the analysis profile mode in Tree View. Delete Analysis Profile: data file will have no attached analysis profile Edit Analysis Profile: CSA Editor like user interface used to generate the required time stream and signal analysis signal. Analyze Process Control Analysis Range Selection: select the analysis range by dragging the analysis range cursor in the pane included the source time stream or input the time or point range in control pane.
