Keysight Technologies introduces high-fidelity PCIe digitizers

August 20, 2015

Keysight Technologies, Inc. announced the availability of the high-fidelity digitizer application option for its U5303A 12-bit PCIe® digitizer.

The new BB1 application option provides enhanced performance by:

  • Compensating the analog-to-digital converter (ADC) and the front-end distortion
  • Minimizing the interleaves spurs
  • Reducing the overall noise bandwidth

This results in highly improved and uniform measurement fidelity across the useful bandwidth, which greatly benefits RF and wireless frequency domain measurements. The digitizer’s post processing compensation also delivers better spurious-free dynamic range (SFDR) and intermodulation product (IMx) specifications. 

This high-fidelity digitizer allows customers to select one of the five available settings that best fit their applications, from 1.6 GS/s with 650 MHz instantaneous bandwidth, down to 100 MS/s with 50 MHz instantaneous bandwidth. The achievable data acquisition length is up to 64 MSamples per channel.

“The BB1 option was developed for test applications that require higher dynamic range and excellent SFDR fidelity,” said Thierry Ortelli, Keysight Digitizers R&D manager. “Across the instantaneous bandwidth, high SFDR and linearity performance provide unique capabilities for testing radio frequency integrated circuit components.”

By adding processing capability within the driver, the U5303A ADC card option BB1, coupled with the data analysis software, enables a broad set of RF and wireless measurements, such as error vector magnitude and intermodulation distortion.
