2. 下限需要考虑到不同测试方法的测试时间的影响,比如给一个32K的钟,机台需要构造更长的采样向量。 PART02 : ATE如何测试PLL 两种方法:时域和频域测试,如下: 方法1. ATE time measurement unit ( TMU)测试。(时域,需要额外的TMU license,因此常不采用。) 实施步骤:ATE 构造TMU TASK。TMU可以非常高精度地根据...
nism involves the suppression of electron transfer from APBA to the N-GQDs unit, thereby inhibiting photoinduced electron transfer and initiating internal charge transfer. At an optimal pH of 7, the protonated α-amine and ε-amine groups of lysine interact with the amide and boronic acid moieties...
方法1. ATE time measurement unit ( TMU)测试。(时域,需要额外的TMU license,因此常不采用。) 实施步骤:ATE 构造TMU TASK。TMU可以非常高精度地根据task设置trigger到上升沿的时刻,因此可以通过两个上升沿的差值计算出频率,支持多次采样,如下图所示: 方法2. 构造采样向量,离散傅里叶公式计算频谱,频谱的最大和第...
