Gas Turbine Monitoring
Gas Turbine Monitoring Customer Case A customer who designs and develops turbo-machinery uses automated data-acquisition and reduction routines. The complete system can sequentially scan up to 144 pressures, 40 electrical signals, and 50 temperatures. It can also acquire and analyze dynamic pressure/vibration signals as well as the scanned steady-state data. They do precise pneumatic traversing for high-performance radial-flow stages. Using a computer-controlled data-acquisition system, the detailed internal pressures and temperatures can be acquired and processed. Laboratory data files are generated, which can be directly used to process the impeller-cover static pressure data. The data can also be automatically processed [...]
Avionics Bus Monitoring
Avionics Bus Monitoring Customer Case The requirement is to monitor anomalies on an avionics bus that controls systems aboard spacecrafts. The customer will know typical rise times, and therefore, will look for anomalous high-voltage pulses that may occur due to sunspots or cosmic rays. An A/D card with at least 12-bits of vertical resolution is required to capture anomalous glitches for characterization. The required sampling speed is 50 KHz, on two simultaneous channels that monitor two bus lines. The input signal bandwidth is typically 4 KHz. The customer would like to write his own data acquisition application programs in [...]

Radar Altimeter
Radar Altimeter Customer Case In this RADAR application the customer has pulses coming in at 1660 Hz. For every pulse they need to capture 500 samples which, at that rate, will amount to 1.7 Megs of data every second. The experiment will be running for at least a few minutes. They would then like to log all the captured data to the PC host memory. The final requirement is for the system to be on the PCI bus. By having the system on the PCI bus, the customer can stream the data directly to the PC's memory, which is [...]
Ultra High-Speed Radar
Ultra High-Speed Radar Customer Case This application requires the acquisition of very fast analog signals at relatively slow sample rates for a long period of time. In other words, the input bandwidth requirement is very high (1 GHz), but the sampling rate needs to be no more than 5 or 6 MSPS. The most important requirement is that the acquisition must go on, without any breaks, for many hours. The customer does not need very high dynamic range. In fact, a 4-bit A/D converter will be sufficient. The customer has already identified a 4-bit A/D chip from TRW which [...]
Radar Rackmount System for Large Record Lengths
Radar Rackmount System for Large Record Lengths Customer Case The customer needs to acquire data from his radar system at a sampling rate of 1.5 MSPS for two channels (I & Q). At the moment, this data must be acquired for at least 10 seconds, but the record length may increase by almost 100 times in the future. This equipment needs to be installed in a rackmounted environment, so the host computer must have rackmount capability. An integrated monitor is also important as it eliminates the need to purchase a rack-mounted monitor. Keyboard and mouse must also be rackmountable. [...]
Interfacing to Offset IF Radar Altimeter
Interfacing to Offset IF Radar Altimeter Customer Case The customer is using an offset IF radar to map forest terrain density. The equipment will be mounted in an aircraft, which will also be carrying a Global Positioning System (GPS) for reference. The plane will fly at an altitude of 10,000 feet. A 512 ns radar pulse will be sent out and a return pulse will be received about 20 uS later, from which 10,000 samples will be acquired. After the pulse is received, there will be a relatively long re-arm time of about 250 to 300 uS for the [...]
Trigger Out Modification for CP500 Class Boards
Trigger Out Modification for CP500 Class Boards Customer Case Many A/D applications including Ultrasonics, Radar, Lidar, Hard Disk testing and CCD capture require maximal synchronicity between a trigger and the sampling clock. GaGe Case Solution GaGe now offers the TRIGGER OUT option as a means of synchronizing systems to the sampling clock on GaGe's CP500-class of A/D and scope cards, including CS8500, CS12100 and CS1250. The need for synchronicity can be understood by considering a typical ultrasonic pulse-echo system. An ultrasonic pulser-receiver generates ultrasonic pulses from a transducer which, microseconds later, receives echo signals reflected from a test specimen. [...]
Monitoring Critical Variables
Monitoring Critical Variables Customer Case The customer wanted a quick visual inspection of many readings of slow varying parameters. Readings of pressure, temperature and voltages had to be compared with reference values and the differences had to be displayed in analog fashion in the form of a simple visual display. A Go/No Go decision had to be reached almost instantly. GaGe Case Solution The solution suggested by a major electronics company was to multiplex the differences 32 readings a channel for two channels, this gives a total of 72 reading in one display. The zero line is the no [...]
Hopkinson Bar Testing (Stress Pulse Reaction Testing)
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 as "Hopkinson Bar" testing. Multiple sensors pick up the reaction of the material and provide outputs which need to be digitized. These outputs are transient signals of approximately 2 Volts and have a rise time of approximately 600 nanoseconds. The resulting system must be programmable [...]
