Deep PCI Capture of Fast Charge-Couple Device (CCD) Array Data
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 [...]

MEMS and Capacitance-Based Semiconductor Wafer Measurement
MEMS Technology and Capacitance-Based Wafer Measurement Micro-electrical-mechanical systems (MEMS) are tiny devices that house electrical and mechanical components on a single silicon chip or integrated circuit (IC). They integrate mechanical structures with electronics that are normally fabricated with complementary metal-oxide-semiconductor (CMOS) technologies. In addition to miniaturization, the benefits of MEMS include expanded functionalities at lower cost and with improved performance and reliability. With MEMS devices, critical physical dimensions range from smaller than one micron (µ) to larger than several millimeters (mm). In complex systems, multiple moving elements may be controlled by integrated electronics. Examples of the mechanical components in [...]
PAxx Power Analyzers using External Current Sensors: Application Notes
Current Sensors use two main techniques. A current transformer divides current. So for instance a 100:1 current transformer would see an input of 10A and output 100mA. Note that this technique is only useful for AC current. When using a current transformer you can directly input the current into one of our internal shunts as long as you stay within the current limitations of the input. Notice that current transformers are inductive so they act as a low pass filter. If you use a current transformer it is important to select a transformer that will work accurately at your frequency [...]

MTI Instruments’ Accumeasure HD System Proven to Be Highest Resolution Capacitance System in the World
Lockport, IL, April 9, 2021 /PRNewswire/ — MTI Instruments, Inc. (“MTI Instruments”), a wholly-owned subsidiary of Mechanical Technology, Incorporated, (NASDAQ: MKTY), announced today that its Accumeasure HD system technology has been proven to measure distances as small as 69 picometers, setting a new bar for capacitance systems. The results were recently published in a white paper by Kevin Harding of Optical Metrology Solutions. Harding’s white paper can be accessed on MTI Instruments’ website. Harding’s independent study confirmed the findings of an internal experiment by MTI Instruments that concluded the Accumeasure HD system can provide picometer-level accuracy when used with [...]

Laser Scanning for Eye Diseases
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
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
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 [...]
