Certain mating devices (like the 33GG50 thru and on-wafer probes) have center pins that can move laterally if
bumped. Be sure the pins are roughly centered (using the magnifying loupe in the accessory kit or a
microscope) before mating.
As-Shipped Configuration
Figure 2-3 on page 2-3 shows the MA25400A module-to-bracket orientation, connection assignments, and
torque values in the as-shipped configuration. It is easier to make the cable connections before mounting the
module to the bracket. The shipping container provides the following components for one module:
• MA25400A Module, mounted in bracket assembly
• Bracket Assembly and Knurled Thumbscrews, M3 x 8 mm, four each, holding the module into the
bracket

To avoid connector damage or inaccurate measurements, before making any connections, ensure
the connectors are clean, undamaged, and meet pin depth specification. Observe connector torque
requirements where indicated in this guide.
