Powered and operated through a USB Type-C cable, Analog Discovery 3 is a 9MHz (or 30MHz) 125Msample/s 14bit oscilloscope, a logic analyser, an arbitrary waveform generator and more from Digilent. “Analog Discovery 2, AD3’s predecessor, has been used as a learning tool in hundreds of universities, and as a flexible benchtop tool by thousands of professional engineering companies and organisations ...
I am not sure why pulse generator buffers are so fascinating at the moment. It could be that the workshop’s only crystal-backed generator that can run from 0% to 100% duty cycle is still broken, or it could be that it is simply an enjoyable bite-sized problem to ponder at idle moments. Anyway, here is the idea that occurred instead ...
Rigol has introduced an eight channel microwave generator that works across 9kHz to 20GHz and can deliver related coherent signals or independent signals. Called DG5208, it is one of the DSG5000 range, which also includes units with 2, 4 or 6 channels, and versions which top-out at 12GHz. If eight channels are still not enough. multiple instruments can be connected ...
Having waxed lyrical about the Pelton wheels on Madira, I felt the need to post some pictures of the huge UK-made Diesel engines that supplied the bulk of the islands power for decades. The top one is a 750kW Mirrlees Bickerton & Day of Stockport diesel oil and gas oil engine with a Brush alternator, made in 1951 and decommissioned 1992 ...
RF instruments from Siglent, the SSA5000A spectrum analyser and the SSG5000A RF signal generator for satcom, radar and mobile comms developers are now available from Telonic Instruments. The SSA5000A spectrum analyser has an operating range of 9kHz-26GHz and the SSG5000A RF signal generator operates at 9kHz-20GHz. Both instruments support X- and K-band measurements for microwave frequency bands. Two models in ...
Siglent has announced a spectrum analyser and a RF generator for use at 20GHz to support X and K-band measurement. SSA5085A (right) is the spectrum analyser, which works across 9kHz to 26.5GHz and offers -165dBm/Hz DANL and 105dBc/Hz phase noise, according to the company. Options include analogue and digital modulation analysis, and demodulation, including for AM, FM, ASK, FSK, PSK, ...
Researchers from Chung-Ang University in Korea have developed a harvester that collects energy from breath in a gas mask, and have used it to power a harmful gas sensor. The harvester is a form of teng (tribo-electric nano-generator, explained at the bottom here) that use motion and electric charge to cause an ac current in an external circuit. This one ...
Bombora Wave Power has completed indoor water tank testing of a floating energy platform that combines support for a wind turbine with wave energy harvesting. Evaluated at the University of Edinburgh’s FloWave facility, “the integrated platform was tested under a wide range of conditions, including extreme waves”, said Bombora head of loads and modelling Peter Arnold. “Analysis is currently underway, where ...
Researchers in Japan have micro-fabricated a thermoelectric generator for IoT devices from non-toxic materials. The proof-of-concept consists of 36 junctions, each made from p-type Mg2Sn0.8Ge0.2 working against n-type bismuth. “The output voltages of thermoelectric conversion modules and devices generally decrease as their sizes diminish,” according to the Japanese National Institute for Materials Science (NIMS). “An approach to overcoming this miniaturisation-related ...
Scientists in India have created random numbers from a 2-d material heterostructure that pass US NIST (National Institute of standards and Technology) SP 800-90B and SP 800-22 testing. It is “an all-electronic van der Waals heterostructure-based device capable of detecting discrete charge fluctuations for extracting entropy from physical processes, according to the researchers in the paper ‘A high-quality entropy source ...
