The system shall shall consist of two primary components: data acquisition hardware and controlling software. The data acquisition hardware shall consist of a mainframe into which cards can be added to expand it channel capacity. Each channel shall have built-in signal conditioning that is fully programmable. Programmable parameters shall include gain setting, cutoff frequency, automatic balance and zero, calibration, and excitation voltage. Digital-to-analog converters shall also be provided. The hardware shall be designed to interface with a PC using an IEEE-488 interface. PC compatible software shall be provided for control of all aspects of operation of the data acquisition hardware. It shall provide a menu driven interface for configuring the hardware and documenting the configuration. The software shall have capabilities to display test data during and after testing and shall provide for test data storage in a variety of formats. Detailed requirements follow: Data Acquisition Hardware - Data acquisition system capable of digitizing at any speed up to a minimum of 250,000 channels per second. 16-bit analog to digital converter resolution. Minimum of 4-Mbytes of acquisition memory expandable to 256-Mbytes. SCSI interface for connection to external laser or hard disk mass storage device. 80 channels of analog input expandable to a minimum of 200. Programmable gain on each individual channel. Gain steps of 1, 2, 4, 8, 10, 20, 40, 80, 100, 200, 400, 800, 1000, 2000, and 4000. Programmable low-pass 8-pole Butterworth filter on each individual channel. Cutoff frequency programmable from 5-Hz to 20-kHz. Simultaneous sample and hold on each channel. Plus or minus 10 full-scale, full-differential voltage input. Input protection to plus or minus 50 volts continuous, 1000 volts transient 80 dB minimum common mode rejection . Constant voltage sensor excitation with remote sense. Each excitation channel shall be programmable and have excitation values of plus 10, and plus 5 volts minimum. Computer controlled shunt calibration and voltage substitution calibration. Computer controlled auto balance and auto zero. 4 channels of analog output expandable to a minimum of 50. Plus or minus 10 volt output. 16-bit resolution. Accuracy: plus or minus 0.05%. Linearity: plus or minus LSB. Dynamic Range: 96dB. Output Impedance: 600 Ohms. Filtering: Plug in selectable 3-pole Butterworth reconstruction filters. The system shall sample channels in any order without reducing sampling speed. Internal or external scan synchronization. IEEE-488 communication interface. Programmable sub-multiplexing of individual channels to minimize volume of data collected. Output for external calibration activation. Programmable triggering for start of data acquisition including pre-trigger and post-trigger options. Shipping cases for all components. All required connectors shall be included. Data Acquisition Software -The software to be furnished with the system shall control every aspect of programming the system to acquire, display, store, and document a test. It shall operate on a DOS and/or Windows based PC (personal computer) and communicate with the data acquisition system using the IEEE-488 interface built into the data acquisition hardware mainframe. It shall be menu driven and have on-line context sensitive help available for all input parameters. The software shall have the features enumerated below. Test configurations shall be programmed and downloaded to the data acquisition system. The configuration can be stored for repeated use and can be modified for use in a new test setup. It shall generate a printout documenting all test setups. Sensor definition table. This table shall define which channels are to be measured, sensor types, engineering units, data conversion factors, gain and filtering settings, alarm checking, and balance and calibration options. The system shall automatically check test configurations and flag invalid configuration settings. System verification of equipment functionality and display and document the test results. This function shall provide an end-to-end checkout of the data acquisition system by injecting a voltage into the front end of the input modules to verify the input modules, gains, analog-to-digital converter and storage media. Those channels specified to be balanced prior to testing in the sensor definition table shall be balanced and those specified for shunt calibration shall be calibrated and the results recorded. System noise measurement by performing a channel scan with all excitation outputs set to zero and recording the results. Measurement of system internal voltages and excitation voltages. Real-Time Data Display. The software shall display data as it is acquired. The data shall be displayed either graphically or in tabular form. The graphical displays shall include time series plots and bar graphs showing peaks. Real-time display of the data shall not impact the acquisition of the data. When acquiring data at high speed, the real-time display may skip points so that the acquisition rate is not affected. Data Review. After completion of a test, display of the test data shall be available in all of the forms available during testing. In addition, zooming functions on the time series shall be available as well as histogram displays. Data storage shall be available in a variety of output formats including formats compatible with Lotus 1-2-3, Excel, dBASE, DADiSP and generic data formats including binary, floating point, and delimited ASCII. Data Calculations. The software shall have the capability to manipulate the test data using polynomial equations, averages, peaks, trigonometric functions, hyperbolic trigonometric functions, logarithms, and do calculations for strain gage rosettes. Automatic restart of acquisition after power failure. Automatic data transfer to host computer during testing when selected. Triggering Functions. The system shall operate from a variety of trigger sources and have both pre- and post-trigger capabilities. Trigger data acquisition based on programmable data limits on any channel or combination of channels. When using combinations of channels, boolean And/OR operators shall be used to specify trigger conditions. Trigger checking shall be done on all specified channels at the full rated speed of the digitizer. Ability to trigger based on the trigger conditions being met for a programmed minimum length of time. Triggering from an external contact closure. Triggering from the PC keyboard. Functions for documenting test data. This shall include the capability to document particular events occurring in the data set as well as documenting the test data in general. Alarm monitoring and display. Event marking. Printing compatibility with Hewlett-Packard laser printers.
