These are mechanical test analogous to testing electronics through the temperature and humidity range, using shake tables as well as EMI, static and discharge tests after the usual bench tests for test waveforms and power supply variations. The area where current electronic design testing falls flat on its face is the testing of firmware and software. Reliance is given to Beta testing by prospective customers, not exactly ideal.

The manufacturer may have, but by having various products from various manufacturers be tested by the same machine under the same parameters, allows comparison of the products directly, at some level.

The manufacturer, in most cases, has done all these tests before they have, and probably came up with some more punishing tests.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
