Frequency Analysis Measurements with the New 10-bit PCIe Digitizer

Up to 10 GS/s and more than 2 GHz Instantaneous Bandwidth per Channel

Key Features:

-One channel at 10 GS/s or two channels at 5 GS/s, DC up to 2.5 GHz bandwidth

-Dual full scale range 250 mV and 1 V

-Low noise density, low distortion and optimized frequency response flatness

 

Keysight High-Speed Digitizers Team announces capability of more than 2 GHz instantaneous bandwidth on the U5310A 10-bit PCIe high-speed digitizer.

This unique ADC card is designed for frequency analysis such as wireless, telecommunication and spectroscopy applications.

The new U5310A high-speed digitizer features one channel at 10 GS/s or two channels at 5 GS/s, DC up to 2.5 GHz bandwidth and dual full scale range at 250 mV and 1 V.

We developed proprietary ICs for the U5310A. In particular, low noise and low distortion signal conditioning amplifier to drive interleaved ADCs and specific clock distribution to minimize the clock jitter and spurious. Moreover, optimized frequency response flatness provides enhanced measurement accuracy.

“With those proprietary technologies, Keysight provides the unique solution to interleave DC coupled 10-bit ADCs without adding distortion while providing low full scale and wide bandwidth input” said Daniel Frund, Analog and IC Design Manager, Keysight’s Digital and Photonics Center of Excellence.”

Here below some examples of frequency analysis measurements:

1) Frequency response (nominal) to a 100 MHz single tone input signal at -1 dBFS, acquired at 5 GS/s, without equalization, and using 1V FSR.
