Introduction High-speed digitizers are indispensable tools in the military and aerospace industries, revolutionizing the way data is captured, processed, and analyzed. These advanced devices enable precise measurement and real-time monitoring of complex systems, from radar and communication systems to electronic warfare and avionics. By converting analog signals into high-resolution digital data at unprecedented speeds, [...]
High-Performance Digitizers in Semiconductor Manufacturing Applications PC-based high-speed, high-resolution digitizers perform critical data acquisition functions during semiconductor fabrication, die packaging, and final chip testing. Introduction Data acquisition is a critical element of quality control and compliance testing during three stages of semiconductor manufacture. The first stage is fabrication, in which [...]
Ultrasonic Tissue Characterization Customer Case This customer's application is Ultrasonic Tissue Characterization. Their ultrasonic sensors transmit 16 signals. The customer's requirement is to capture 512 points on the 16 channels, average them together, and then store the data in a buffer, with the system running continuously. They would like to be able to update [...]
Digitizing Ultrasonic Signals Customer Case The customer has an ultrasonic signal that he wants to digitize with either 8 or 12-bit resolution. The sampling rate required for this application is a minimum of 16 MSPS (20 MSPS is acceptable). Finally, the data must be acquired for a full 10 seconds. The data is not [...]
Digital Ultrasonic Array Data Capture Customer Case A customer possesses a commercial medical diagnostic ultrasonic system. The ultrasonic sensing head consists of an ultrasonic generator transducer and an 8' x 8' two-dimensional array of receiver transducers. The sensing head is pressed against the tissue under study and the generation transducer is periodically excited so [...]
Arbitrary Ultrasonic Generator Customer Case Ultrasonic generation pulses must be varied to accommodate different types of ultrasonic transducers. General-purpose highly damped contact transducers are usually excited by a wideband, spike-like pulse that is provided by many common pulser/receiver units. Lightly damped transducers, used for example in high power generation, require a narrowband tone-burst excitation [...]
Pipeline Testing Customer Case The customer wants to test pipelines for corrosion and cracks. They intend to use a small robot which they can send into the pipeline. This robot's purpose is to test the pipe by ultrasound and magnetic field for cracks, corrosion and other damage. The customer is using 2 different types [...]
Hopkinson Bar Testing (Stress Pulse Reaction Testing) Customer Case This customer is involved in testing materials for how they react to stress pulses. The idea is to introduce a stress pulse into the Material Under Test (MUT) and monitor it as it travels through the material. This method of material characterization is also known [...]
Vibration Test Equipment Instrument Grade Chassis Customer Case The customer is in the business of building Vibration Test equipment for semiconductor, automotive and aerospace industries. Their product is currently housed in Industrial Grade PCs which they integrate themselves. They currently purchase the chassis from an off-shore company. Their major problem is product differentiation: their [...]
Non-Destructive Testing (NDT) Customer Case This customer manufactures non-destructive test equipment which allows customers such as steel mills to test the quality of their end-products. Presently, the ultrasound frequencies being used are centered at either 5 MHz, 10 MHz or 15 MHz. The worst case analog bandwidth requirement in this case is 35 MHz. [...]
