Signal Integrity Challenges Abound
As new digital designs increase in data rates to 28 Gb/s and
beyond, signal integrity issues become more challenging.
Additionally, industry standards such as IEEE 802.3 ba/bj/bm
(40 Gb/100 Gb Ethernet), Optical Inter-networking Forum (OIF)
CEI 3.0, Fibre channel, PCI Express, USB, and InfiniBand require
the use of TDR/TDT and S-parameter measurements to ensure
compliance and system interoperability.
A fully-integrated 86100D TDR/TDT/S-parameter
measurement system
Designed for both novice and expert users alike, the Keysight
Technologies, Inc. N1055A remote head module provides time-
domain reflectometry and transmission (TDR/TDT) capability
for the 86100D DCA-X oscilloscope platform, providing fast
and accurate impedance and S-parameter measurements on
high-speed designs that have up to 16 ports. The 86100D DCA-X
oscilloscope mainframe can be configured with one to four
N1055A TDR/TDT plug-in modules to provide a 2- to 16-channel
TDR/TDT measurement system that is both economical and
accurate. The 2/4 port TDR/TDT remote heads can be configured
with sampler bandwidth of 35 GHz or 50 GHz, providing
single-ended and differential measurement capability including
True-Mode stimulus functionality.
Measurements include:
Time-Domain Reflectometry (TDR)
–– Impedance measurements
–– Locate the position and nature of each discontinuity
–– Propagation/time delay
–– Excess reactance (capacitance or inductance)
–– Effective dielectric constant
Time-Domain Transmission (TDT)
–– Step response
–– Propagation/time delay
–– Propagation velocity
–– Rise-time degradation
–– Near-end crosstalk (NEXT)
–– Far-end crosstalk (FEXT)
–– Skew
S-parameters (86100D-202)
–– Return loss
–– Insertion loss
–– Crosstalk
–– Mode conversion
–– Differential-to common-mode conversion (SCDxx)
–– Common-to differential-mode conversion (SDCxx)
–– Phase
–– Group delay
2- to 16-channel TDR/TDT/S-parameter measurement system.
Fast and accurate S-parameter measurements.
