产品总览：
准确测量静态电流可能是一个挑战。测量从nA到A的动态电流是一个更大的挑战。根据电流水平，必须使用不同的精密测量电阻，该电阻代表电源中的测量范围。
N6781A，N6782A，N6785A和N6786A具有多个电流测量范围，因此可以对其进行调整以测量器件的不同工作状态。关闭，睡眠，待机和发送模式。此外，前三个范围还支持Keysight Technologies，Inc。专有功能称为“无缝测量范围”。启用此功能后，随着被测设备（DUT）汲取的电流发生变化，SMU会立即自动检测到哪个电流测量范围将返回最精确的测量值，并无缝地更改到该范围。与SMU的内置18位数字化仪结合使用时，无缝的测量范围可实现前所未有的有效的约28位垂直分辨率。这提供了无与伦比的生产率提高，并提供了前所未有的功耗了解。
N6784A还具有多个测量范围，但不支持无缝测量范围。

Overview
Measuring static current accurately can be a challenge. Measuring dynamic currents from nA to A is an even greater challenge. Depending on the level of current, a different precision measurement resistor must be used, representing a measurement range in the power supply.
The N6781A, N6782A, N6785A, and N6786A have multiple current measurement ranges making them tuned to measure the different operating states of a device; off-, sleep-,standby-, and transmit-mode. In addition, the top three ranges support a Keysight Technologies,Inc. exclusive feature called “seamless measurement ranging.” When you enable this feature, as the current drawn by the device under test (DUT) changes, the SMU automatically and instantaneously detects which current measurement range will return the most precise measurement and changes to that range seamlessly. When combined with the SMU’s built-in 18-bit digitizers, seamless measurement ranging enables unprecedented effective vertical resolution of ~28-bits. This provides unrivaled productivity gains and insights into power consumption never possible before. Only Keysight’s N6780 Series SMUs let you visualize current drain from nA to A in one pass and one picture unlocking insights to deliver exceptional battery life.
The N6784A also has multiple measurement ranges, but does not support seamless measurement ranging.
