SPECIFICATION
The EDAS/VIS System includes a Hardware: DAIB Data Acquisition Interface Box + DAB. Data Acquisition Board and a Software: EDAS/VIS-SOF.
Data Acquisition and Virtual Instrumentation Software:
1. DAIB. Data Acquisition Interface Box: Metallic Box Dimensions: 310 x 220 x 145 mm. approx. Front panel: 16 Analog inputs (1 block with12 voltage channels and 1 block with 2 current channels (4connections)).Sampling velocity 1,250,000 samples per second for EDAS/VIS 1.25 Version.Sampling velocity 250,000 samples per second for EDAS/VIS 0.25 Version. 2 Analog outputs. 24 Digital inputs/outputs, configurable as inputs or outputs, with 24 state led indicators. These digital inputs/outputs are grouped in three portsof eight channels (P0, P1 and P3).4 Digital signal switches 0-5V. 2 Analog signal potentiometers 12V. Main ON/OFF switch. Inside: Internal power supply of 12 and 5 V. Potentiometer. Back panel: Power supply connector. SCSI connector (for connecting with the data acquisition board). Connecting cables.
2. DAB. Data Acquisition Board: For EDAS/VIS 1.25 Version: PCI Data acquisition board (National Instruments) to be placed in a computer slot. Bus PCI. Analog input: Number of channels= 16 single-ended or 8 differential. Resolution=16 bits, 1 in 65536. Sampling rate up to: 1,250,000 S/s (samples per second).Input range (V)= 10V. Data transfers=DMA, interrupts, programmed I/0. Number of DMA channels=6. Analog output: Number of channels=2. Resolution=16 bits, 1 in 65536. Max. output rate up to: 833 KS/s. Output range(V)= 10V. Data transfers=DMA, interrupts, programmed I/0. Digital Input/Output: Number of channels=24 inputs/outputs. Port 0 up to 8 MHz. Timing: Counter/timers=2. Resolution: Counter/timers: 32 bits. For EDAS/VIS 0.25 Version: Sampling rate up to: 250,000 S/s (samples per second). Analog output: Max. output rate up to: 10 KS/s. DigitalInput/Output: Number of channels=24 inputs/outputs. Port 0 up to 1 MHz. Rest of characteristics are the same than EDAS/VIS 1.25 Version.
3. EDAS/VIS-SOF. Data Acquisition and Virtual Instrumentation Software: Compatible with actual Windows operating systems. Amicable graphical frame. Configurable software allowing the temporal/frequency representation of the different inputs and outputs. Visualization of a voltage of the circuits on the computer screen. It allows data store in a file, print screens and reports of the signals at any time.
