Keysight Technologies U5303A 12-bit PCIe digitiser

Keysight Technologies has introduced the high-fidelity digitiser application option for its U5303A 12-bit PCIe digitiser, developed for test applications that require higher dynamic range and good SFDR fidelity.

The BB1 application option provides enhanced performance by compensating the analog-to-digital converter (ADC) and the front-end distortion, minimising the interleaves spurs and reducing the overall noise bandwidth. This results in improved and uniform measurement fidelity across the bandwidth, benefiting RF and wireless frequency domain measurements. The digitiser’s post processing compensation also delivers better spurious-free dynamic range (SFDR) and intermodulation product (IMx) specifications.

Users can select one of the five available settings from 1.6 GSa/s with 650 MHz instantaneous bandwidth down to 100 MSa/s with 50 MHz instantaneous bandwidth. The achievable data acquisition length is up to 64 MSa/channel. By adding processing capability within the driver, the U5303A ADC card option BB1, along with the data analysis software, also enables a broad set of RF and wireless measurements, such as error vector magnitude and intermodulation distortion.
