VectorStar ME7838 Modules RM PN: 10410-00311 Rev. H 4-1
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.
