Precision Arbitrary Waveform Generator

07 March 2011 – Agilent Technologies added a high-resolution, wide-bandwidth, 8- or 12-GSa/s modular instrument to its portfolio of arbitrary waveform generators. The new M8190A arbitrary waveform generator is able to deliver simultaneous high resolution and wide bandwidth along with industry-leading spurious-free dynamic range and very low harmonic distortion. Precision arbitrary waveform generation is required for realistic testing of low-observable aircraft systems and for high-density communications used in satellite communications systems.

This unique functionality allows radar, satellite and electronic warfare device designers to make reliable, repeatable measurements and create highly realistic signal scenarios to test their products.With up to 14 bits of resolution, the M8190A makes it easy for designers to distinguish between signals and distortion in their test scenarios and stress their devices more rigorously. The instrument’s 2-GSa memory allows designers to create longer test scenarios that are more realistic.

“The M8190 AWG allows engineers to approach reality when they create test scenarios,” said Jürgen Beck, general manager of Agilent’s digital and photonic test business. “Because the M8190A simultaneously offers greater fidelity, high resolution and wide bandwidth, customers can create signal scenarios that push their designs to the limit and bring new insights to their analysis.”

The exceptional performance of the M8190A arbitrary waveform generator is made possible by a proprietary digital-to-analog converter designed by the Agilent Measurement Research Lab. Fabricated with an advanced silicon-germanium BiCMOS process, the DAC operates at 8 GSa/s with 14-bit resolution and at 12 GSa/s with 12-bit resolution. At 8 GSa/s, the Agilent DAC delivers up to 80c-dB SFDR, an industry-leading specification.

This technology breakthrough eliminates the trade-off between high resolution and wide bandwidth so measurements are more reliable and repeatable and engineers are less likely to misinterpret glitches in the waveforms as analog output.

The M8190A runs on an AXIe modular system, which is designed for high-performance instrumentation. It can be used with either a 2-slot or 5-slot chassis.
