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 provide as much as 50 sine wave carriers on one single output channel. This function supplies a brand new means for engineers and scientists to provide and independently management multi-tone sine alerts. DDS, which is brief for “Direct Digital Synthesis”, is a robust approach for producing high-purity alerts (sometimes sinewave cores, additionally known as carriers or tones) with ultrafast switching between output frequencies and positive frequency decision. The merchandise can produce a number of tones, overlaying a broad vary of working frequencies as much as 200 MHz. It makes them uniquely agile sign sources which can be appropriate for demanding purposes in industries resembling 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 provide from 2 to 24 channels. For purposes needing greater than 50 tones, the bigger NETBOX models assist as much as 300, or it’s doable 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 hundreds, or ±5 V for high-impedance.
Extraordinarily quick parameter modifications
The velocity at which these merchandise can change the traits of a tone is what makes them completely different to traditional sign turbines. Absolutely programmable, modifications will be made utilizing easy instructions virtually immediately. New settings for a tone’s frequency, amplitude and part in addition to amplitude slopes and frequency slopes will be initiated throughout runtime, or by way of preloaded sequences of DDS instructions. Thousands and thousands of DDS instructions will be saved within the on-board reminiscence. Setting modifications will 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 straightforward and programmable means for customers to provide trains of waveforms, frequency sweeps or finely-tuneable references of varied frequencies and profiles. Functions will be present in industrial, medical and imaging techniques, community evaluation and even communication expertise the place information is encoded utilizing part and frequency modulation on a service. One other utility is the management of lasers via AODs and AOMs, as usually utilized in quantum experiments. Laser management will be made at very excessive speeds with just some 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 consumer can management superior features like s-shaped or custom-shaped frequency transitions, {custom} pulse envelopes, AM or FM modulation and extra.
Simple system integration
Working underneath Home windows or Linux working techniques, the 96xx sequence DDS turbines will 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 straightforward option to management the merchandise.
Two devices in a single
Ought to there ever be a must generate extra complicated waveforms, the 96xx sequence may also be transformed into a totally useful 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 resembling Single Shot, Loop, Single Restart, A number of Replay, Gated Replay, Streaming (FIFO) or Sequence Replay are all supported.
