Waveform generator boasts high resolution, wide bandwidth

The M8190A arbitrary waveform generator (AWG) introduced by Agilent Technologies boasts simultaneous high resolution and wide bandwidth along with spurious-free dynamic range and very low harmonic distortion. This functionality helps make reliable, repeatable measurements and create realistic signal to test radar, satellite and electronic warfare 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-GSa memory allows designers to create longer test scenarios that are more realistic.

A proprietary digital-to-analog converter (DAC) designed by the Agilent Measurement Research Lab improves the performance of the M8190A. 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. This eliminates the tradeoff between high resolution and wide bandwidth so measurements are more reliable and repeatable.

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.

The M8190A AWG will be available in April with an entry price of $79,000.
