描述

U4164A 邏輯分析儀模塊提供兩個(gè)新的工作模式：四倍采樣狀態(tài)模式和 10 GHz 1/4 通道時(shí)序模式。四倍采樣狀態(tài)模式能夠從每路輸入的單一探測(cè)點(diǎn)在兩個(gè)獨(dú)立調(diào)節(jié)閾值上對(duì) 4 個(gè)不同位置進(jìn)行采樣，意味著 U4164A 對(duì)空間的需求可以進(jìn)一步減少，并滿足 DDR4、DDR5、LPDDR4 和 LPDDR5 等高數(shù)據(jù)速率信號(hào)的探測(cè)需求：4 個(gè)不同的讀和寫數(shù)據(jù)采樣位置，獨(dú)立的 2.5 Gb/s 以上數(shù)據(jù)速率上升沿/下降沿采樣。1/4 通道（10 GHz）時(shí)序模式可以支持高達(dá) 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(xiàng)新特性，能夠幫助高速數(shù)字和 DDR/LPDDR 存儲(chǔ)器設(shè)計(jì)工程師加快系統(tǒng)啟動(dòng)和調(diào)試速度。新特性包括時(shí)序模式偏移校正控制、雙采樣狀態(tài)模式雙閾值、時(shí)鐘滯后控制（時(shí)鐘關(guān)閉后時(shí)鐘輸入存在噪聲，該特性可以調(diào)整狀態(tài)模式的噪聲靈敏度）以及非常深的存儲(chǔ)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).
