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. [...]

Silicon Carbide vs. Silicon in EV Power Electronics
Compare silicon carbide vs. silicon for electric vehicle (EV) power electronics and learn about SiC wafer measurement. As demand for electric vehicles (EVs) continues to grow, manufacturers are comparing two semiconductor technologies, silicon carbide and silicon, for power electronics applications. Silicon carbide (SiC) provides the high temperature resistance, low power consumption, rigidity, and support for smaller, thinner designs that EV power electronics need. Examples of SiC’s current applications include on-board DC/DC converters, off-board DC fast chargers, on-board battery chargers, EV powertrains, and automotive lighting for LEDs. According to Automotive World, SiC technology could also drive future EV innovations [...]
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. [...]
MTI Instruments Fulfills Historic Order for the United States Air Force
ALBANY, N.Y., November 16, 2020 — MTI Instruments, Inc. (“MTI Instruments”), the operating subsidiary of Mechanical Technology, Incorporated (OTC Pink: MKTY), announces the completion of its historic order for the United States Air Force, a $3.3 million contract awarded publicly in May 2020 that includes 52 PBS-4100+ engine vibration measurement and balancing systems. This order was made pursuant to the multi-year contract entered into by MTI Instruments and the United States Air Force in July 2016 and marks the single largest order of PBS-4100+ Systems received by MTI Instruments to date. MTI fulfilled the order in its entirety with [...]
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 [...]
Electrical Cable Testing
Electrical Cable Testing Customer Case The customer needs to test, certify, and troubleshoot electrical cable that is used on-board Navy ships. They must test and isolate for cross-talk signal distortion as well as other signal anomalies that occur in the 100 - 1000 kHz frequency range. Signal simulation is also required, and the customer would prefer to not do any software programming. GaGe Case Solution A high-resolution digitizer in conjunction with an analog signal generator will fulfill the hardware requirements. The CompuScope 1602 provides 16-bit vertical resolution and sample rates of up to 10 MS/s with the optional 10 [...]
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 [...]

EV Batteries Need Thickness Gauging for Lower Costs and Higher Performance
EV batteries need to cost less and last longer. Until the e-mobility industry solves these challenges, electric vehicle (EV) adoption won’t match the hype that’s driven by Tesla, the established automakers, and a host of startups who are attracting investors. According to Axios, the expense of owning an electric vehicle will exceed that of owning a conventional one until EV batteries cost less than $100/KWh to produce. Unfortunately, the EV industry isn’t expected to hit that target for another ten years. Yet, there is some encouraging news. Less expensive and better performing EV batteries are just a few years [...]
