Keysight's PCIe 12bit data-acquisition card got an upgrade. The company has now launched an improved FFT option for its U5303A, sporting two channels and sampling rates from 1Gsample/s to 3.2Gsamples/s.

The new U5303A is intended for use in astronomy, physics, and environmental measurements requiring frequency-domain signal processing, the card performs continuous real-time FFTs at full sampling rate. Spectra accumulation is also enabled in the new card that can be utilised for radio astronomy.

With a nominal bandwidth of DC to 2GHz, the U5303A converts even low frequencies near 0Hz not observable with an AC front-end. While AC coupling introduces BF noise, DC coupling ensures measurement fidelity. By increasing the resolution from 8 bits to 12 bits, the FFT option computes a 32-kpoint FFT in 10.24µs at 3.2 Gsamples/s.
