Popular Oscilloscopes Boost Signal Integrity

Keysight Technologies unleashes the latest Infiniium UXR-Series oscilloscopes, with models ranging from 13 GHz to 110 GHz of true analog bandwidth and greater signal integrity. The series delivers a low noise floor and high vertical resolution to ensure measurements are not impacted by oscilloscope noise and signals are represented accurately. As a result, eye diagrams are significantly more open, and true margins and performance can be determined.

  • 10-bit vertical resolution and industry leading signal integrity for superior effective number of bits (ENOB), leading to faster compliance testing with higher margins;
  • sampling rates of 256 Gsamples/s per channel on 40 to 110 GHz models and 128 Gsamples/s per channel on 13 to 33 GHz models, creating accurate reconstruction of high-speed signals;
  • up to four full-bandwidth channels with less than 35 fsRMS of inter-channel intrinsic jitter providing accurate timing and skew measurements;
  • an optional full factory grade self-calibration module which ensures ongoing measurement accuracy while reducing the need to take the unit out of service,
  • a chipset based on a Keysight-proprietary Indium Phosphide (InP) process that enables exceptionally wide bandwidth and extremely low noise floor.


Keysight also offers two instruments that, when paired with the UXR-Series oscilloscopes, offer a full end-to-end solution from stimulus to analysis for PAM4 and 400G, 600G, as well as terabit coherent optical interconnect designs.  These include the:

  1. N4391B Optical Modulation Analyzer (OMA) –a compact, real-time oscilloscope-based OMA designed specifically for complex optical data transmission and terabit measurement challenges.
  2. M8194A 120 Gsamples/s arbitrary waveform generator (AWG) –Keysight's fastest AWG delivers a new level of stimulus performance for generating challenging formats such as 64 Gbit 64QAM (quadrature amplitude modulation) and other wideband modulation schemes.


More information and specs are available for the Infiniium UXR Series real-time oscilloscopes, the N4391B OMA, and the M8194A AWG.
