Understanding and displaying the J operator
A plus times a plus is a plus. A plus times a minus is a minus. A minus times a plus is a minus. A minus times a minus is a plus. Because none of these operations results in a negative product, we must confront the hard reality that the square root of a negative […]
PXI chassis carries 58 W of power and cooling per slot
The PXIe-1095 chassis is the first PXI Chassis with 58 W of dedicated power and cooling per slot. This represents a 50% increase in power and cooling per slot compared to previously released NI PXI Express chassis. In addition to higher power, the new chassis also features a significant reduction in fan noise in its […]
Radio communications tester supports RF, PHY layer throughput measurements for 6CA terminals
The measurement capability of the Anritsu MT8821C Radio Communications Analyzer has been augmented with the release of LTE-Advanced software solutions. When the new LTE-Advanced FDD DL CA 6CCs Measurement Software MX882112C-061 and LTE-Advanced TDD DL CA 6 CCs Measurement Software MX882113C-061 for LTE-Advanced/LTE Advanced Pro DL 6CA are installed, the MT8821C supports RF and PHY […]
Why the sky is blue: LiDAR puts a focus on measuring Raleigh scattering
Most people assume the sky is blue because through a process of refraction we see the higher-frequency, shorter-wavelength end of the spectrum. This explanation is incorrect. For one thing, if the entire sky is blue, what happened to the rest of the spectrum? It’s complicated. In actuality, the blue appearance of the sky and yellow […]
Fast chart recorder samples at 200 kHz
AstroNova, Inc. (NASDAQ: ALOT), a global leader in data visualization technologies, today announced the launch of the Everest®EV-5000, the newest chart recorder from AstroNova Test & Measurement. The EV-5000 sets a new standard for mission-critical applications in which remote data is acquired, measured, printed and stored for back up. “The new EV-5000 is a direct replacement […]
Sensor acquisition modules work with high-def scopes
A Sensor Acquisition Module (SAM40) works exclusively with the Teledyne LeCroy 12-bit HDO family of scopes. The SAM40 provides up to 24 input channels for low frequency (sensor signal) acquisition and analysis. It connects to a 4 or 8-channel Teledyne LeCroy 12-bit resolution high-definition oscilloscope (HD4096 HDOs and MDAs) to provide Analog+Digital+Sensor (up to 8+16+24 […]
VIDEO: Trace Detection And Function Controls In The Tektronix RSA306B Spectrum Analyzer
A Tektronix RSA306B PC-based spectrum analyzer is connected to the output from a Tektronix RTSA V3 Demo Board in order to demonstrate trace detection and function controls. Hi and welcome to our 72nd Test and Measurement Video. Today we are continuing our demonstration of the Tektronix RSA306B PC-based spectrum analyzer. This recent Tektronix offering makes […]
Narrowband-IoT over-the-air test setup works with reverberation test chambers
Keysight Technologies, Inc. today announced the collaboration with Bluetest on the successful creation of a narrowband – internet of things (NB-IoT)) over-the-air (OTA) solution for use in Bluetest Reverberation Test Systems (bluetest.se/products/chambers). The solution, used by one of Japan’s top operator customers, demonstrates the market leading position of both companies in NB-IoT test. “We are […]
Measuring oscillator jitter
In digital electronics, jitter is a particularly insidious form of noise, to be understood, measured and where possible mitigated. Jitter is short-term, generally considered less that one second, deviation from the design intent. It consists of timing fluctuation in periods or transitions within cycles. An eye diagram tells the whole story. While vertical closing of […]
