Agilent 16441A User’s Guide, Edition 4

User's Guide

Agilent 16441A R-Box is one of the accessories available for Agilent 4155/4156 
Semiconductor Parameter Analyzers. The R-Box is used to add a series resistance (0

 

W

, 10 k

W

, 100 k

W

, or 1 M

W

) between the 4155/4156’s SMU output and your test 

device (DUT), and is useful for the following measurements:

negative resistance measurement

R-Box is effective for the negative resistance measurement, because SMUs 

cannot

 measure negative resistance.

breakdown measurement

R-Box is effective for preventing excessive current, thus preventing damage to 
DUT when sudden voltage change occurs.

This manual consists of the following sections:
