1 U4205A Overview

The U4205A 34-Channel 38-pin Single-Ended Mictor Probe

The U4205A is a direct connect, 34- channel, single- ended, 38- pin probe

designed to be compatible with the AMP MICTOR 38- pin connector. It is

pin- compatible with target systems that were designed for the Keysight

E5346A 38- pin probe, thus enabling you to use Keysight's latest logic

analyzers with target systems that were designed for older Keysight logic

analyzers. The U4205A is compatible with the Keysight 16851A,

16852A,16853A and 16854A portable logic analyzers, and the U4154A

logic analyzer module. It is capable of capturing state (synchronous) data

at clock speeds up to 600 MHz, at data rates up to 600 Mb/s, with signal

amplitudes as small as 300 mV peak- to- peak.

The Keysight E5346- 68701 or E5346- 68700 probing connector kit is

required for connecting the U4205A probe to your target system. The kit

contains five mating connectors and five support shrouds. The connectors

and shrouds may be ordered separately if desired. See the table on

page 32 for part numbers.
