Technical Overview
Introduction

Low current measurement is a key performance metric for picoammeters and
electrometers, which often specify atto-ampere (aA) level current measure- Important words used in
ment resolution. In addition to ultra-low current measurement capability, it is the document:
also very important to have other measurement functions such as iltering to
