512Msample memory boosts next generation AWG cards
Spectrum Instrumentation has launched six next-generation Arbitrary Waveform Generator (AWG) card instruments for PC systems with large sample memories to create complex waveforms.
segments. The cards also feature a FIFO streaming capability that enables new waveform data to be read over the fast PCIe bus (at rates of up to 700 MB/s) while replaying already transferred information. This flexibility allows users to create ultra-long, single shot waveforms or constantly changing, burst-type signals such as those found in radar, ultrasound, LIDAR or sonar systems.

For applications that require the connection of AWGs and Digitizers, such as stimulus-response or closed-loop applications, Spectrum's Star-Hub piggy-back module synchronizes up to 16 different M2p class products. The M2p.65xx AWGs matches with the M2p.59xx 16bit digitizers released in 2018 which offer one to eight channels with sampling rates between 20 MS/s and 125 MS/s. The Star-Hub distributes a common clock and trigger signal to each channel ensuring fully synchronous operation. Star-Hub systems are also perfect for situations where multiple test points, or arrays of sensors, need to be stimulated by different test signals at the same time.

The cards are fully programmable and drivers are provided, free of charge, to support the most popular languages (such as C++, VB.NET, C#, J#, Delphi, Java or Python code) as well as third party software tools such as LabVIEW and MATLAB. Alternatively, users can simply run Spectrum's own software, SBench 6 Professional.

SBench 6 enables the user to control all the modes and settings of the AWG via a simple, easy-to-use, interface. The software is designed to support multi-channel operation and has a host of built-in features for waveform display, signal generation, data analysis and documentation. Basic signals can be created using the software's EasyGenerator function that produces waveforms like sine waves, triangles or rectangles with programmable frequency, amplitude and phase. More complex signals can be created using mathematical equations or imported from other programs or devices (such as digitizers or oscilloscopes) using Binary, ASCII, or Wave formats.

Once installed in a PC, the AWG cards are easy to integrate with other test and measurement
