GaGe has filled out its line of PCIe digitiser boards – essentially ADCs for PCs – with three new dual-channel models: one with with 250MHz bandwidth and 14bit 500Msample/s sampling, and two 125MHz 250Msample/s models, one with 16bit resolution and the other 14bit. The “digitisers boast ENOB [effective number of bits] of ~11+ typical”, according to the company. Inputs are ...
Danish company Vind-Vind is developing a turbulence model for the effect of wind on structures in complex environments. It will eventually include the atmosphere high above the volume of interest with wind gusts from different directions. As such, said Vind-Vind CEO Per Jørgensen, wind-tunnel measurements are not good enough and he needed real-world measurements throughout a large volume of atmosphere ...
Spectrum Instrumentation has added a GPU-based digital down-conversion (DDC) option to its PC-based ‘SCAPP’ software, used with its PCIe signal digitiser cards – effectively ADCs for PCs. Working with sufficiently-powerful Cuda-based GPUs, the DDC option allows on-the-fly baseband signal extraction, and is offered as an alternative to FPGA-based DDC and its associated programming. “The GPU, which can have thousands of ...
German digitiser company Spectrum has introduced a dual-channel sampler board – an ADC board – that takes 12bit samples on both channels simultaneously at 3.2Gsample/s. Called M5i.3321-x16, it has 1GHz bandwidth front-end amplifiers with programmable full-scale ranges from ±200mV to ±2.5V, plus variable offset. Other models in the M5i family offer 2GHz bandwidth. The full input capacity can be streamed continuously ...
Spectrum Instrumentation has pushed PC-based data acquisition to 12.8Gbyte/s using 16-lane Gen 3 PCIe. “That is nearly twice as fast as any other PCIe digitiser currently on the market,” claimed the German company. “It allows the cards to continuously run at their maximum sampling rate of 6.4Gsample/s with 12bit resolution, and transfer the acquired data directly to PC memory for ...
Fuel cell control systems will need to be highly sophisticated if the technology is going to find its way into transport, according to German hydrogen and fuel cell research centre ZBT, which is developing it for trucks and busses. In hydrogen fuel cells, hydrogen is fed to the anode while air is fed to the cathode. An anode catalyst, typically ...
Nvidia’s ‘Cuda’ graphics processors, with their high bandwidth PCIe interface, have opened the door to fast, but simple, instrumentation-grade DSP, according to Spectrum Instrumentation. Spectrum is a maker of digitisers – effectively low-noise multi-channel ADCs, some PCIe-based. Cuda is an Nvidia parallel number-crunching technology, that allows direct PCIe peripheral to GPU interaction without the host CPU getting involved. “Currently digitisers ...
Spectrum Instrumentation has introduced a new generation of 16bit digitiser cards with a PCIe interface. Called M2p, they offered doubled sample rate and less noise compared with the previous 12, 14 and 16bit M4i generation, which they will replace. 13 new models are available for general sale, with different combinations of sampling rate (20, 40 or 80Msample/s) and number of input ...
