Automatic Accelerometer Calibration System Customer Case The customer's Automated Accelerometer Calibration System provides NIST traceable calibration of most accelerometer types, whether self-generating piezo-electric or accelerometers requiring current or voltage excitation. The output of the accelerometer can be charge or voltage, single- ended or differential, AC or DC coupled, isolated or grounded. In building the automatic calibration system, the need is for optimum versatility with regards to the data acquisition card. LabVIEW is the desired control software, and Signal to Noise Ratio and high vertical resolution is of utmost importance for the small variations that occur in Vibration and Shock [...]

Deep PCI Capture of Fast Charge-Couple Device (CCD) Array Data Customer Case A customer wants to digitize data from a 256x256 infrared charge-couple device (CCD) array. The array data is clocked at 4 MHz through two output channels. Exactly two clock cycles occur between 12-bit line signals, and a dozen or more clock cycles occur between successive frames. The customer wants to digitize the data for a minute or more. Since light level signals from the array can vary widely in amplitude, 12-bit resolution is required. GaGe Case Solution The customer will use the CompuScope 512/PCI with the External [...]

Laser Scanning for Eye Diseases Customer Case In scanning for non-ablative eye diseases, the customer has a requirement for high vertical resolution while remaining cost effective. By shooting a low-powered laser into the eye (low enough to not cause lasting damage), they are able to determine whether there are any problems in the eye cells. The laser does cause minute damage that is repaired by the antibodies of the eye. The requirement is to capture laser reflections and analyze them. The scan takes place over the entire eye and there are therefore multiple acquisitions. The main obstacle is that [...]

Echocardiography Experiment Customer Case This customer is involved in an Echocardiography experiment. The customer already has an ultrasound imager with a built-in A/D converter which can output 12-bit image data which must be analyzed with the customer's proprietary algorithms on a PC platform. In order to accomplish this, it is required to bring 12-bit digital data at 35 MHz clock rate into a PC. This data is arriving in a burst mode with a repeat frequency of 12.8 KHz with 1000 samples arriving in 28 us followed by no data for the next 50 us. There are 512 such [...]

Ultrasound Imaging Customer Case This customer's application involves capturing ultrasound echoes from a medical imaging system, to be used in bedside monitors, defibrillators, intervascular ultrasound, ECG, etc. The live imaging rate is 30 frames per second (fps). Each image frame depicts a full 360-degree circular section. A frame is 240 echoes, so the pulse repeat frequency (PRF) is 7200 Hz, or one echo every 140 us. The customer anticipates signals at 50 MHz with a 50% bandwidth (the passband must extend to at least 75 MHz). The echo duration is 15 us; the signal size is roughly +/- 70 [...]
