Chapter 6 — 3744x-Rx Receiver Module
6-1 Introduction
This chapter provides a description of the 3744A-Rx and 3744E-Rx Receiver Modules. The modules are used
with the VectorStar ME7838 Series Broadband/Millimeter-Wave (BB/mm-Wave) VNA System.
The module is typically ordered as an accessory to the ME7838 system. When ordering this module, the base
VectorStar VNA must have Noise Figure Option 041. 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. Note: 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.
6-2 3744x-Rx Millimeter-Wave Module and Bracket
As-shipped Configuration
Figure 6-1 shows the module-to-bracket orientation, connection assignments, and torque values of a 3744A-Rx
in the as-shipped configuration. The 3744E-Rx has the same mechanical profile. 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:
• 3744A-Rx or 3744E-Rx Module, mounted in the bracket assembly
• Bracket Assembly and Knurled Thumbscrews, M2 x 8 mm, six each, holding the module into the bracket
