Description
Overview
The Keysight N4916B de-emphasis signal converter enables R&D and test engineers to accurately emulate next-generation transmitter de-emphasis using multi-tap Finite Impulse Response (FIR) filtering. It supports one pre-cursor and two post-cursors with individually adjustable de-emphasis levels up to 12 dB. With DC-coupling that tolerates unbalanced pattern streams and transparent jitter handling, the N4916B enables emulation of real-world de-emphasis and jitter conditions for precise receiver characterization.
Key Features
- Adjustable de-emphasis: one pre-cursor and two post-cursors, 0 to 12 dB each
- Supports data rates from 660 Mb/s to 14.2 Gb/s
- DC-coupled: tolerates non-balanced patterns and training sequences
- Transparent to jitter on data and clock signals
- Flexible usage with J-BERT N4903B, ParBERT 81250A, or other pattern generators
- Programmable via J-BERT N4903B or stand-alone operation
- Optional clock multiplier (opt. 001)
- Compact form factor
Applications
- Next-generation gigabit serial standard validation
- Transmitter de-emphasis emulation and testing
- Receiver jitter tolerance characterization with de-emphasis
- Cable and fixture distortion compensation in test setups
- High-speed serial I/O validation and characterization
