Keysight Technologies Introduces Enhanced FFT Option

Keysight Technologies has introduced an improved version of the FFT option, now available on the U5303A PCIe 12-bit high-speed data acquisition card. It is suited for astronomy, physics applications and environmental measurements requiring frequency domain processing.

Key features of the new FFT version include:

• Single and dual channel mode selectable on-the-fly
• High-speed FFT on 32,768 data values computed in 10.24 μs at 3.2 GS/s
• Input bandwidth up to 1.4 GHz at 3.2 GS/s, resolution of 97.66 kHz per spectral line
• Highly improved fixed point arithmetic that eliminates deteriorating effects

“Thanks to a remarkable dynamic range, this new fast Fourier transform version allows performance of sensitive observations in highly interfered environment,” said C. Monstein, radio engineer at Institute for Astronomy, ETH Zürich. “With 12-bit resolution, the card enables observation of -110 dBm signals in -30 dBm interfered spectrum. Even in very strong FM band we can still see the solar radio burst structure without cross-modulation or ghosts, which wasn’t possible before with previous instruments at ETH, such as Phoenix-generations, Argos, Callisto, and so forth. Keysight’s on-going collaboration with the institute enables continuous technological improvements.”
