Chapter 2 — MA25400A mmWave Module
2-1 Introduction
This chapter provides a description of the MA25400A millimeter-Wave (mmWave or as labeled, mm-W)
Module. The MA25400A Module is used with the VectorStar ME7838 Series Broadband/mmWave
(BB/mmWave) VNA System.
When the ME7838 system is ordered, the typical configuration provides a 3739C Broadband Test Set and two
mmWave modules to be used with the VNA. Each module is characterized for a specific VNA Serial Number
and a specific VNA Test Port. Additional information for heat sinking and user-defined mounting is given in
Chapter 8. Complete installation documentation is in the applicable VectorStar ME7838 Series System
Installation Guide. Refer to Section 1-3 “Related Documentation” on page 1-2 for the document part number.
2-2 MA25400A mmWave Module and Bracket
MA25400A Module Installation
The flange interface is based on a standard UG-387 waveguide flange and one connects to it by first lining up
the alignment pins and then mating the flanges.
Standard captive waveguide screws are used with an exposed shank. This is useful since both mating flanges
may have threaded holes. Thread the screws all the way into the mating flange (so the shank clears) before
mating to the module. This simplifies assembly and avoids cross-threading.
Use a 6 N-cm torque wrench for these screws (one is in the accessory kit). Tighten in a star pattern (or slowly
tighten opposite sides sequentially when using two screws).

2-2 PN: 10410-00311 Rev. H VectorStar ME7838 Modules RM
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

Caution
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.

Chapter 4 — 3743A/AX and 3743E/EX
mmWave Module
4-1 Introduction
This chapter provides a description of the 3743A/AX and 3743E/EX millimeter-Wave (mmWave or as labeled,
mm-W) Modules. The modules are used with the VectorStar ME7838 Series Broadband/mmWave
(BB/mmWave) VNA System.
When the ME7838 system is ordered, the typical configuration provides a 3739C Broadband Test Set and two
mmWave Modules to be used with the VNA. Each module is characterized for a specific VNA Serial Number
and a specific VNA Test Port. Additional information for heat sinking and user-defined mounting is given in
Chapter 8. Complete installation documentation is in the applicable VectorStar ME7838 Series System
Installation Guide. Refer to Section 1-3 “Related Documentation” on page 1-2 for the document part number.
4-2 3743A/AX and 3743E/EX mmWave Module and Bracket
As-shipped Configuration
Figure 4-1 on page 4-2 shows the module-to-bracket orientation, connection assignments, and torque values of
a 3743A/AX in the as-shipped configuration. The 3743E/EX has the same mechanical profile. It is easier to
make the cable connections before mounting the module to the bracket. The following components are
provided:
•3743A/AX or 3743E/EX Module
•Bracket Assembly and Knurled Thumbscrews, M2 x 8 mm, six each, holding the module into the bracket
Caution
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.
