De-Emphasis Signal Injection Enables Robust Receiver and Board Designs:
Industries First De-Emphasis Signal Converter
Robust Receiver Designs
The Keysight N4916A de-emphasis signal converter enables design and test engineers to accurately characterize gigabit serial ports and channels that operate with de-emphasized signals. This results in more robust receiver designs, with reliable operation in real PC board environments.
De-emphasis is a commonly used technique for transmitting electrical signals at gigabit data rates to compensate for signal degradations caused by printed circuit boards, e.g. by motherboards, add-in cards or backplanes.
The most popular high-speed electrical standards require transmitter de-emphasis, sometimes also called pre-emphasis. These standards are: PCI Express®, SATA 3 Gb/s, fully buffered DIMM, CEI, and 10 Gb Ethernet.
User Interface
The N4916A de-emphasis signal converter can be controlled from the graphical user interface of the J-BERT N4903A high-performance serial BERT and the 81141A/81142A serial pulse data generators.
The de-emphasis signal parameters can be controlled via the user interface of the Keysight J-BERT N4903A or 81141/81142A serial pulse data generators.
