User Guide

Cables Compatibility

The N2823A 39 inches (1 m) long cable is 

compatible with the following Keysight test 

fixtures:
• N7015A Type-C high-speed plug test fixture
• N7016A Type-C low-speed signal access and 

control fixture.

The N5448B 10 inches (25cm) long cable is 

compatible with the following Keysight probe 

head:
• N5444A InfiniiMax III 2.92mm differential probe 

head

These cables can also be used for any RF/ 

microwave applications that require 

phase-matched 2.92mm cable connections with 

excellent measurement repeatability.

To adapt the 2.92mm male connectors of the 

N2823A/N5448B cables and the N7015A test 

fixture, use the Keysight 3.5mm female-to-3.5mm 

female adapter (part number 5061-5311). 

This adapter is also recommended to connect the 

2.92mm male connector of the N2823A/N5448B 

cables to the channel input of an Infiniium V 

Series, Z Series, or 90000X oscilloscope.
