Spectrum launches six new AWG cards with ±12 V signal generation | Spectrum

AWG cards with ±12 V high amplitude signal generation
Spectrum Instrumentation has added six new Arbitrary Waveform Generators (AWGs) to its recently released M2p.65 xx series of PCIe cards. The new AWGs extend the product families capabilities by boosting the available output range, so that waveforms can be generated with amplitude swings of up to ±12 V into 1 M? or ±6 V into 50 ?. To achieve the higher output voltage ranges the cards have been fitted with additional amplification and larger cooling plates. This makes the cards a little wider, so that they occupy two PCIe slots, but they are still just 168 mm in length. The small size allows them to fit into almost any PC, turning it into a powerful and flexible waveform generator. The M2p.65xx series AWGs use the latest 16-bit Digital-to-Analog Converters and feature a fast PCIe x4 interface with up to 700 MByte/s streaming speed. Users can select output speed rates of either 40 MS/s (M2p.654x series) or 125 MS/s (M2p.657x series) and models with one, two or four channels per card.

Each channel features its own DAC and output stage. Multi-channel cards share a common clock and trigger to ensure full synchronization and the output stages incorporate four switchable filter paths to help optimize signal quality. The flexible output stages combine with the high resolution 16-bit DACs to enable the generation of signals with very low distortion, exceptional dynamic range and a high signal-to-noise ratio.
Oliver Rovini, CTO at Spectrum, said: “One of the main limitations of most AWGs is their ability to generate accurate high amplitude waveforms. These new AWG cards offer a cost-effective solution in one fully integrated package. As such, they should be of interest to anybody wanting to generate larger test signals in the DC to 60 MHz range. The ability to reproduce high quality signals is always valuable to engineers and scientists who need to stimulate a system, or component, with waveforms that are high precision, easily adapted, and mimic real operational conditions.”

Mixed Mode AWG

Switching the multi-purpose I/O lines to digital output adds another four synchronous output channels to the AWG. A single AWG card can then generate four analogue outputs and four digital outputs in parallel with full speed. This is especially helpful when interfacing with external equipment in experiment control or for OEM projects. Adding the new MIX-MODE-MODULE, which offers 16 additional digital lines, an AWG of the 65xx series could carry a total of 20 multi-purpose I/O-lines!

Five Year Warranty

The Spectrum M2p.65xx series AWGs are in full production and available for immediate delivery. All cards are shipped factory tested and include a base version of Spectrum's SBench 6 software for first tests. “The M2p series AWG products represent the culmination of nearly 30 years of PC-based instrumentation design and production. As a result, we’re proud to give an industry-leading, five-year warranty on our products,” stated CEO Gisela Hassler. “Furthermore, software and firmware updates are free of charge for the lifetime of the product. Support is done directly by our skilled in-house team of engineers – normally within a couple of hours after receiving the request.”
