Plug-in boards are now available for blocking the airflow in an otherwise empty OpenVPX slot. They come in 3U and 6U sizes in the 5HP (1.0 in) width commonly used in the backplane architecture. The air slot blocker boards help optimize airflow by forcing the available airflow to pass through utilized slots. They fill spare […]
Overview of electrical measuring instruments
Here’s a quick review of some basic instrumentation common to most engineering work benches. Ammeter The ammeter is the basis for many other electrical measuring instruments. Whether you are measuring volts or ohms, essentially inside the instrument you are measuring current. Measurement of current in a circuit is somewhat problematic because all the electrical energy […]
Another Covid causality: The James Webb telescope
NASA has announced it will pause work on the James Webb Space Telescope because of the ongoing COVID-19 pandemic. The launch is still currently on the books for 2021, but there are questions about whether that date will hold. The James Webb Space Telescope, successor to the Hubble and Spitzer instruments, was originally scheduled to […]
Precision programmable linear ac power sources generate super-clean outputs
A new range of precision programmable linear ac power sources include over 20 different models ranging in power from 500 VA to 30,000 VA. Compared to more commonplace PWM switching ac power sources, the LMX Series uses linear technology to offer superior performance with respect to output noise, voltage distortion, output impedance and peak current […]
Wideband I/Q data recorder enables field-to-lab tests with midrange equipment
The R&S IQW100 brings signals from the real world into the laboratory to simulate real-world test environments, used in combination with selected midrange R&S signal analyzers and generators. The R&S IQW100 supports recording and replaying signals with bandwidths up to 200 MHz and sampling rates up to 250 MS/sec. For the many worldwide users of […]
Video analyzer and generator offers comprehensive testing for DisplayPort 2.0
The quantumdata M42d Video Analyzer and Generator is the industry’s first DisplayPort 2.0 protocol test instrument. The DisplayPort 2.0 standard provides for data rates up to 20 Gb/sec per lane for an overall aggregate bandwidth of 80 Gb/sec, going well beyond the DisplayPort 1.4 standard’s aggregate rate of 32.4 GB/sec. These data rates support high […]
How to test for Covid-19 in 45 minutes
The FDA recently authorized use of a fast test for the Covid-19 virus that reportedly can finish up in about 45 minutes. The test was developed by Cepheid, a molecular diagnostics company that is part of Danaher Corp. The beauty of the new test is that it runs on existing Cepheid hardware called the GeneXpert […]
Video: Lab equipment for students, working from home in Seattle
Imagine being a university student studying EE/ECE, physics, chemistry, biology, or other sciences and not having access to your lab equipment. What will you do, sitting there bored at home because your university is closed? Digilent, a company that serves the academic market with measurement and FPGA tools for students, has lowered its prices on […]
Can you really make a respiratory ventilator in a car factory?
Mechanical ventilators are making headlines these days because of the Coronavirus-19, widely regarded as a flu but which is actually a respiratory disease that attacks the lungs. The key to minimizing the death toll for those with virulent infections is the availability of mechanical ventilators that help people breathe when their own lungs can’t. Reports […]
Real-time hand-held spectrum analyzer captures IQ data
IQ capture and IQ streaming options for the Field Master Pro MS2090A make the real-time spectrum analyzer (RTSA) the first handheld analyzer to capture 110 MHz of IQ data. The MS2090A can conduct comprehensive spectrum analysis in a variety of general-purpose applications, including military intelligence and government regulations. With 110 MHz bandwidth and 200 MSps […]
