Lossy cables, fixtures, and connectors all blur the signal before it reaches your oscilloscope. That&#039;s why engineers turn to de-embedding\u2014a mathematical process that removes channel effects so you can see the signal as if it came straight from the transmitter.<\/div>\r\n<\/div>\r\n<div class=\"inner-block text option-text\">\r\n<p>But here&#039;s the catch: while de-embedding restores lost high-frequency content, it also amplifies oscilloscope noise. Think of it like sharpening a blurry photo\u2014you recover detail, but the grain and static get magnified, too. For compliance tests and design validation, that added noise can make the difference between a passing eye diagram and a costly redesign.<\/p>\r\n<p>\u00a0<\/p>\r\n<\/div>\r\n<div class=\"inner-block text option-image\">\r\n<div class=\"image\"><img decoding=\"async\" src=\"https:\/\/cnrood.com\/wp-content\/uploads\/2026\/03\/quietchannel-blog-figure-1-400x155-1.jpg\" alt=\"\" \/>\r\n<p class=\"caption\">Figure 1: Frequency content of a 20 Gb\/s PRBS signal before and after channel loss.<\/p>\r\n<\/div>\r\n<\/div>\r\n<div class=\"inner-block text option-text\">\r\n<h4>Why Traditional De-Embedding Amplifies Noise in Oscilloscope Measurements<\/h4>\r\n<p>Modern\u00a0<a href=\"https:\/\/www.tek.com\/en\/products\/oscilloscopes\" target=\"_blank\" rel=\"noopener noreferrer\">oscilloscopes<\/a>\u00a0already work hard to keep their noise floors low, but when you apply a de-embed filter, both the signal and the oscilloscope&#039;s noise get boosted together. The result? Cleaner edges aren&#039;t as clean as they should be, and jitter measurements can be misleading.<\/p>\r\n<p>For short traces, this may only cost you a few percent of margin.
