Designing an Interface Between a P6434 Probe and a
Target System

This section provides you with some guidelines for designing your own P6434
probe interface on the target system. The guidelines contain information on the
following topics:

H

Mictor connectors

H

Dimensions and placement of connectors

H

Mechanical layout and pinout of connectors

H

AMP pinout (preferred)

H

Nonstandard pinout (not recommended)

H

Probe channel assignments

H

Loading and equivalent circuits

Mictor Connectors and Latch Housings

The P6434 probe contains a 38-pin Mictor connector. Table 3 lists Mictor
connectors you can purchase from AMP that are compatible with the probe and
compatible latch housings and connectors from Tektronix.
