Migrating from the 4155C and 4156C
to the B1500A
Application Note
Introduction
Recent advances in device and process technology present new parametric characterization challenges.
This includes both more precise measurement requirements of not only static but also dynamic device

data.
The Keysight Technologies, Inc. B1500A Semiconductor Device Analyzer is the next generation of
parameter analyzers and it is capable of meeting these new challenges. For many years the Keysight
4155C and 4156C Semiconductor Parameter Analyzers have represented the de facto industry standard
for semiconductor parameter analyzers. However, as this application note will show, the B1500A can
both meet these new challenges as well as perform all of the functions found in the 4155C/4156C.
This application note details the top 3 reasons to migrate from the 4155C/4156C to the B1500A:
1. Broader measurement coverage
2. Easy-to-use and intuitive EasyEXPERT software
3. Convenient tools to ease migration from the 4155/4156 to the B1500A
