Introduction

 

 

Agilent E5255A Product Description

 

Resistors

Resistors connected between BIAS path and IV path are for

 

 

protecting DUT from electrical damage. When shipped from

 

 

factory, 0 Ω resistance is used in the E5255A. You can easily

 

 

replace with desired resistors. Refer to Chapter 2. The

 

 

following resistors are furnished with the E5255A:

 

 

• 0 Ω resistors (3 sets with 10 resistors in each set)

 

 

• 1.2 kΩ resistors (3 sets with 10 resistors in each set)

 

 

• 22 kΩ resistors (3 sets with 10 resistors in each set)

 

 

If you replace initial 0 Ω resistors with other resistors, you must

 

 

cut the initial resistors. Then, if you need 0 Ω resistors again,

 

 

use the ones listed above.

 

Be careful about the following when selecting protective resistors:

WARNING

 

• If only one E5255A is installed in the mainframe, total power consumption

 

by resistors must be less than 16W.

• If multiple E5255As are installed in the mainframe, total power consumption by resistors must be less than 32W.

• Consider the current flows to resistor when DUT shorts, and make sure the power consumption by resistor will be within specification of resistor.

Do not use resistors that have specifications inadequate for your applications, which will result in resistors heating up, burning, or smoking.

Be careful about the heating of the rear panel of mainframe or plug-in card, which may be heated by resistors, even if you follow this warning.
