Probing a DUT

N7000/1/2/3A InfiniiMax III+ Handling Guide

Probing a DUT

The probe has been designed to withstand a moderate amount of physical and 

electrical stress. However, with an active probe, the technologies necessary to 

achieve high performance do not allow the probe to be unbreakable. Treat the 

probe with care. It can be damaged if excessive force is applied to the probe tip. 

This damage is considered to be abuse and will void the warranty when verified by 

Keysight Technologies service professionals.

When the probe amplifier is not in use, store it in the probe case. Coil the probe 

cable with these tips in mind:
• Keep the coil’s radius fairly large so as not to induce kinking or bending. Use a 

similar technique as when coiling an extension cord.

• Avoid twisting the cable when coiling by introducing a very slight twist with 

each coil. This allows the cable rotations to lie flat against each other and will 

eliminate the net twisting of the cable in the end.

CAUTION

Probes are sensitive devices and should be treated with care. Do not bend or kink the 

probe amplifier cable. Do not drop heavy objects on the probe, drop the probe from large 

heights, spill liquids on the probe, etc. Any of these examples can significantly degrade 

the performance of the probe.

CAUTION

Do not replace or repair the N2849A QuickTip’s resistor or ground leads. Attempting to do 

so will damage the ability of the tip to mate with the N2848A probe head.

CAUTION

Always mechanically strain-relieve the N2848A QuickTip head and N5439A ZIF head 

before using to protect both your probe accessories and DUT from damage.

CAUTION

Using the N2787A 3D probe positioner with the N5445A browser probe head reduces the 

chance of breaking the browser tips and ensures that the tips maintain solid contact.
