Spectrum Instrumentation launches quick switching multi-tone DDS Devices

Spectrum Instrumentation launches a household of DDS Turbines named the 96xx sequence, forming a brand new product class within the firm’s portfolio. The brand new DDS Devices supply as much as 50 sine wave carriers on one single output channel. This function offers a brand new approach for engineers and scientists to supply and independently management multi-tone sine indicators. DDS, which is brief for “Direct Digital Synthesis”, is a robust method for producing high-purity indicators (usually sinewave cores, additionally known as carriers or tones) with ultrafast switching between output frequencies and nice frequency decision. The merchandise can produce a number of tones, protecting a broad vary of working frequencies as much as 200 MHz. It makes them uniquely agile sign sources which are appropriate for demanding purposes in industries corresponding to biomedicine, communications, semiconductors and quantum science.

The 96xxs sequence includes 12 completely different fashions in three completely different formfactors; PCIe playing cards, PXIe modules and Ethernet devices. A single PCIe or PXIe card can produce as much as 50 completely different low-phase-noise variable-frequency tones and is obtainable with as much as 4 channels. The stand-alone Ethernet devices supply from 2 to 24 channels. For purposes needing greater than 50 tones, the bigger NETBOX items assist as much as 300, or it’s potential to attach a number of playing cards along with the Star Hub synchronization module to create techniques with as much as 400 tones. All fashions present built-in output amplifiers with programmable sign amplitudes as much as ±2.5 V into 50 Ohm masses, or ±5 V for high-impedance.

Extraordinarily quick parameter adjustments

The velocity at which these merchandise can change the traits of a tone is what makes them completely different to standard sign turbines. Totally programmable, adjustments could be made utilizing easy instructions virtually immediately. New settings for a tone’s frequency, amplitude and section in addition to amplitude slopes and frequency slopes could be initiated throughout runtime, or by way of preloaded sequences of DDS instructions. Hundreds of thousands of DDS instructions could be saved within the on-board reminiscence. Setting adjustments could be triggered externally, or by an inner timer, or instantly on command. No transition jitter or glitches seem and the timing decision for sequencing instructions is as small as simply 6.4 nanoseconds.

DDS controls waveforms in Check and Measurement, Communications and Quantum

The 96xx sequence DDS turbines present a simple and programmable approach for customers to supply trains of waveforms, frequency sweeps or finely-tuneable references of varied frequencies and profiles. Purposes could be present in industrial, medical and imaging techniques, community evaluation and even communication know-how the place information is encoded utilizing section and frequency modulation on a provider. One other software is the management of lasers by way of AODs and AOMs, as usually utilized in quantum experiments. Laser management could be made at very excessive speeds with only a few easy instructions – that is in distinction to the extra processing-intensive technique that makes use of an Arbitrary Waveform Generator (AWG) and calls for massive information array calculations. Issuing a small sequence of slope instructions, the person can management superior capabilities like s-shaped or custom-shaped frequency transitions, {custom} pulse envelopes, AM or FM modulation and extra.

Straightforward system integration

Working below Home windows or Linux working techniques, the 96xx sequence DDS turbines could be programmed utilizing programming examples for C++, Python, C#, JAVA, LabVIEW, MATLAB and others in addition to a high-level Python API‘s that present a simple option to management the merchandise.

Two devices in a single

Ought to there ever be a must generate extra complicated waveforms, the 96xx sequence can be transformed into a totally practical AWG. A firmware choice is obtainable that switches the DDS Generator into an AWG, permitting the replay of arbitrary waveforms on all lively channels synchronously. Working modes corresponding to Single Shot, Loop, Single Restart, A number of Replay, Gated Replay, Streaming (FIFO) or Sequence Replay are all supported.
