Test and Measurement Tips
Test setup automates USB Type-C compliance and debugging
New transmitter automated test solutions are designed to meet the demanding requirements of next-generation technologies for large, rapid data transfers and low-latency video displays. Tektronix USB4, Thunderbolt 4 and DisplayPort 2.0 automated compliance and debugging solutions address the most common challenges design engineers face, including test time, signal integrity and Device Under Test (DUT) control. […]
Attenuation networks and their measurement
An attenuator is a four-terminal, two-port network that reduces the amplitude of a signal without distorting its waveform. Attenuators are used in electronic instrumentation to precondition a signal for measurement and display. For example, the commonly-used 10:1 oscilloscope probe attenuates the signal voltage upstream from the analog channel input by a factor of ten, letting […]
Portable, battery-operated dc calibrator offers lab-level accuracy
The XiTRON 2000 series is for metrologists who need superior accuracy and portability when calibrating thermocouple, pressure, flow and dc instrumentation. Delivering laboratory-level accuracy in a battery-powered dc calibrator, the 2000 Series is a cost-effective calibration/simulation tool which is a candidate for applications spanning the consumer, medical, automotive, process control and many other industries. The […]
What is the importance of resolution in an oscilloscope?
When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these are incredibly important specs, often most design work is done well within the limits of most products and the more critical specification to consider is resolution. Did you know that while most […]
The difference between LEDs and photovoltaic cells
LED’s and photovoltaic cells play increasingly prominent roles in our world. Both are semiconductor diodes. The LED or light-emitting diode emits light while the photovoltaic cell converts light to electricity. The LED is a diode that emits light only when forward-biased. Under a forward voltage bias, electrons cross from the n-region and recombine with the […]
Julia-language SDK handles digitizers, generators, digital I/O products
A Software Development Kit (SDK) for programming over 200 different digitizers, generators and digital I/O products uses the Julia programming language. A key feature of Julia is that it has been specifically designed for high-performance applications that require fast processing of data, like machine learning and scientific computing. For example, libraries include optimized source C […]
Mini 15-GHz signal generator fits in your pocket
The Windfreak SynthHD Mini is a software tunable RF signal source that generates signals from 10 MHz to 15 GHz with a 0.01-Hz resolution and an output power of up to 20 dBm. The generator also supports FM, AM, pulse, sweep, and list modulations. It can be programmed for standalone operation, running without any PC […]
Test system reduces development time for DDR5, LPDDR5, GDDR6 memory systems
A comprehensive workflow solution called PathWave Advanced Design System (ADS) 2022 reduces design time and de-risks product development for Double Data Rate 5 (DDR5), Low-Power Double Data Rate 5 (LPDDR5) and Graphics Double Data Rate 6 (GDDR6) memory systems. From cloud computing to autonomous vehicles, the demand for faster memory interfaces is accelerating. A disruptive […]
Active-probe PC-based scopes feature up to 5 GSa/sec real-time sampling, 4-GSa-deep memory
New 750-MHz and 1-GHz models have been added to the four-channel PicoScope 6000E Series, which provide 8 to 12 bits of vertical resolution, and up to 5GSa/sec sampling rate with a 4-GSa memory, allowing these scopes to display single-shot pulses with up to 200 psec time resolution. The four new four-channel models added to the […]
