20 unbiased sine waves as much as 400 MHz might be managed on one generator channel

Spectrum Instrumentation has launched a brand new firmware possibility for its vary of versatile 16-bit Arbitrary Waveform Mills (AWGs) with sampling charges as much as 1.25 GS/s and bandwidths as much as 400 MHz. The brand new possibility permits customers to outline 23 DDS cores per AWG-card, that may be routed to the {hardware} output channels. Every DDS core (sine wave) might be programmed for frequency, amplitude, part, frequency slope and amplitude slope. This allows, for instance, the management of lasers by AODs and AOMs, as typically utilized in quantum experiments, with just some easy instructions – as an alternative of creating giant information array calculations. The DDS output might be synchronized with exterior set off occasions or by a programmable timer with decision of 6.4 ns.

DDS – Direct Digital Synthesis – is a technique for producing arbitrary periodic sine waves from a single, fixed-frequency reference clock. It’s a approach extensively utilized in quite a lot of sign era functions. The DDS performance applied on Spectrum Instrumentation’s AWGs is predicated on the precept of including a number of ‘DDS cores’ to generate a multi-carrier (multi-tone) sign with every provider having its personal well-defined frequency, amplitude and part.

With the flexibility to change between the conventional AWG mode (which generates waveforms out of pre-programmed information) and the DDS mode (which wants just a few instructions to generate sine wave carriers), the Spectrum AWGs are extremely versatile and might be tailored to virtually any software. In DDS-mode, the AWG acts as a base for the multi-tone DDS. The models built-in 4 GByte of reminiscence and quick DMA switch mode then permits the streaming of DDS instructions at a fee as excessive as 10 million instructions per second! This distinctive functionality gives the pliability to carry out user-defined slopes (e.g. s-shaped) in addition to varied modulation sorts (e.g. FM and AM) with easy, easy-to-use, DDS instructions.

For years now, Spectrum AWGs have been efficiently used worldwide in pioneering quantum analysis experiments. Since 2021, Spectrum Instrumentation has been a part of the BMBF (German federal ministry of training and analysis) funding program ‘quantum applied sciences – from fundamental analysis to market’ as a part of the Rymax One consortium. The intention of this consortium is constructing a Quantum Optimizer. The event of the DDS possibility was primarily based on suggestions from the consortium companions and different analysis institutes worldwide.

The flexibleness and quick streaming-mode of Spectrum’s AWGs, which additionally permits information to be streamed straight from a GPU, permits the management of Qubits immediately from a PC. Whereas utilizing an AWG on this manner affords full management of the generated waveforms, the downside is that vast quantities of knowledge must be calculated. This slows the crucial decision-making loop. In distinction, utilizing the versatile multi-tone DDS performance drastically reduces the quantity of knowledge that should be transferred, whereas nonetheless retaining full management. All the important thing performance required for quantum analysis is inbuilt. With only a single command customers can apply intrinsic dynamic linear slope capabilities to supply extraordinarily easy modifications to frequency and amplitude.

In lots of sorts of testing methods, it is very important produce and readily management correct waveforms. The DDS possibility gives a simple and programmable manner for customers to supply trains of waveforms, frequency sweeps or finely tuneable references of varied frequencies and profiles. Purposes that require the quick frequency switching and effective frequency tuning that DDS affords are widespread. They are often present in industrial, medical, and imaging methods, community evaluation and even communication expertise, the place information is encoded utilizing part and frequency modulation on a provider.

The DDS possibility is obtainable now for the total vary of M4i.66xx PCIe playing cards, M4x.66xx PXIe modules, transportable LXI/Ethernet DN2.66x models and multi-channel desktop LXI/Ethernet DN6.66xx merchandise. By merely performing a firmware replace, all beforehand bought 66xx sequence merchandise might be geared up with the brand new firmware possibility. Programming might be carried out utilizing the present driver SDKs which can be included within the supply. Examples can be found for Python, C++, MATLAB, LabVIEW and plenty of extra. The choice is obtainable now.
