This unit
The Tektronix DPP125C Digital Pre-emphasis Processor compensates for signal degradation in high-speed digital communication systems by applying controllable pre-emphasis to enhance signal integrity. It corrects transmission channel impairments through configurable tap-based equalization, enabling accurate data recovery at the receiver and supporting compliance testing across multiple industry standards. The instrument operates as either a standalone device controlled remotely or integrates fully with a BERTScope for unified software control.
