This paper will establish a practical range for the time constants that we need to cover and will illustrate the effectiveness of DSP-based corrections for a few selected time-constant values.

This paper discusses analog-to-digital converter (ADC) resolution (mostly with regard to oscilloscopes)
and considerations for improving resolution using various ADC deployment methods.

The fastest electrical PAM-4 signal is demonstrated. The technology behind the generation of this signal
along with the acquisition of the signal is discussed along with the motivation for generating signals like
this in optical communications research.

Power distribution network testing and validation is an important task in the system design flow. To avoid
unnecessary testing time, the measurement setup, the instruments and the connections should be reusable
for different tasks. Instruments and setups, therefore, whether they work in the time domain or frequency
domain, limit the number of functions that can be performed without changing instruments, or cables or
connections. The paper explores test setups and instrumentations that allow multiple tests being performed
without changing the hardware connections. Real-life test results will illustrate the benefits and limitations
of the setup.

We compare two approaches where the structure of the eye diagram is considered either as a timing uncertainty
or alternatively a vertical uncertainty. We show that only the second view allows accurate BER
evaluation, even if the eye is closed. It follows from BER definition that its proper evaluation should be
based on considering the two portions of the eye diagram, and by their separate integration. With such
understanding of BER, it turns out that the jitter-induced vertical noise can be considered same way as the
signal’s ISI, although correlated with the latter.

Getting a clean signal to your oscilloscope has become a complicated business. How much does probe loading matter? What is the effect of the probe's calibration? Are there reflections to worry about? If you're de-embedding, how do you separate de-embedding problems from signal problems? In this session, practical examples are used to show how these considerations affect high-speed measurements, and how to apply knowledge about the tools at hand to ensure the best results.
