描述
U4164A 邏輯分析儀模塊提供兩個新的工作模式：四倍采樣狀態模式和 10 GHz 1/4 通道時序模式。四倍采樣狀態模式能夠從每路輸入的單一探測點在兩個獨立調節閾值上對 4 個不同位置進行采樣，意味著 U4164A 對空間的需求可以進一步減少，并滿足 DDR4、DDR5、LPDDR4 和 LPDDR5 等高數據速率信號的探測需求：4 個不同的讀和寫數據采樣位置，獨立的 2.5 Gb/s 以上數據速率上升沿/下降沿采樣。1/4 通道（10 GHz）時序模式可以支持高達 1.6 Gb 采樣/輸入。除了新的工作模式外，U4164A 邏輯分析儀模塊還包括多項新特性，能夠幫助高速數字和 DDR/LPDDR 存儲器設計工程師加快系統啟動和調試速度。新特性包括時序模式偏移校正控制、雙采樣狀態模式雙閾值、時鐘滯后控制（時鐘關閉后時鐘輸入存在噪聲，該特性可以調整狀態模式的噪聲靈敏度）以及非常深的存儲器選件（400 Mb 全通道，800 Mb 半通道，1.6 Gb 1/4 通道）。

describe
U4164A logic analyzer module provides two new working modes: quadruple sampling mode and 10 GHz 1/4 channel sequential mode. The quadruple sampling state mode can sample four different locations from a single probe point in each input channel at two independent adjusting thresholds, which means that U4164A can further reduce the demａnd for space and meet the detection requirements of high data rate signals such as DDR4, DDR5, LPDDR4 and LPDDR5: four different sampling locations for reading and writing data, and independent data over 2.5 Gb/s. Sampling along the rising/falling edge of the rate. The 1/4 channel (10 GHz) sequential mode can support up to 1.6 GB sampling/input. In addition to the new mode of operation, the U4164A logic analyzer module includes a number of new features that can help high-speed digital and DDR/LPDDR memory design engineers speed up system start-up and debugging. New features include timing mode offset correction control, double sampling state mode double threshold control, clock lag control (noise in clock input after clock closure, which can adjust the noise sensitivity of state mode) and very deep memory options (400 Mb full channel, 800 Mb half channel, 1.6 Gb 1/4 channel).
