Arbitrary waveform generator

27 April 2011 Test & Measurement

Agilent Technologies added a high-resolution, wide-bandwidth, 8- or 12-GSps modular instrument to its portfolio of arbitrary waveform generators.

The new M8190A is able to deliver simultaneous high resolution and wide bandwidth along with extended spurious-free dynamic range and very low harmonic distortion. This functionality allows radar, satellite and electronic warfare device designers to make reliable, repeatable measurements and create highly realistic signal scenarios to test their products.

Precision arbitrary waveform generation is required for realistic testing of low-observable aircraft systems and for high-density communications used in satellite communications systems. With up to 14 bits of resolution, the M8190A enables designers to distinguish between signals and distortion in their test scenarios and stress their devices more rigorously. The instrument’s 2 gigasample memory allows designers to create longer test scenarios that are more realistic.

The performance of the instrument is made possible by a proprietary digital-to-analog converter. Fabricated with an advanced silicon-germanium BiCMOS process, the DAC operates at 8 GSps with 14-bit resolution and at 12 GSps with 12-bit resolution. At 8 GSps, the Agilent DAC delivers up to 80 c-dB SFDR.

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