Spectrum Instrumentation launches a household of DDS Mills named the 96xx collection, 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 supplies a brand new manner for engineers and scientists to supply and independently management multi-tone sine alerts. DDS, which is brief for “Direct Digital Synthesis”, is a strong method for producing high-purity alerts (usually sinewave cores, additionally referred to as carriers or tones) with ultrafast switching between output frequencies and superb 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 can be appropriate for demanding purposes in industries similar to biomedicine, communications, semiconductors and quantum science.

The 96xxs collection contains 12 totally different fashions in three totally different formfactors; PCIe playing cards, PXIe modules and Ethernet devices. A single PCIe or PXIe card can produce as much as 50 totally different low-phase-noise variable-frequency tones and is accessible 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 models help as much as 300, or it’s doable to attach a number of playing cards along with the Star Hub synchronization module to create programs 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 pace at which these merchandise can change the traits of a tone is what makes them totally different to traditional sign mills. Totally programmable, adjustments may be made utilizing easy instructions nearly immediately. New settings for a tone’s frequency, amplitude and part in addition to amplitude slopes and frequency slopes may be initiated throughout runtime, or through preloaded sequences of DDS instructions. Hundreds of thousands of DDS instructions may be saved within the on-board reminiscence. Setting adjustments may 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 collection DDS mills present a straightforward and programmable manner for customers to supply trains of waveforms, frequency sweeps or finely-tuneable references of assorted frequencies and profiles. Functions may be present in industrial, medical and imaging programs, community evaluation and even communication expertise the place information is encoded utilizing part and frequency modulation on a provider. One other software is the management of lasers via AODs and AOMs, as usually utilized in quantum experiments. Laser management may 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 collection 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.
Simple system integration
Working below Home windows or Linux working programs, the 96xx collection DDS mills may 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 method to management the merchandise.
Two devices in a single
Ought to there ever be a must generate extra complicated waveforms, the 96xx collection can be transformed into a completely practical AWG. A firmware choice is accessible that switches the DDS Generator into an AWG, permitting the replay of arbitrary waveforms on all energetic channels synchronously. Working modes similar to Single Shot, Loop, Single Restart, A number of Replay, Gated Replay, Streaming (FIFO) or Sequence Replay are all supported.
