1. ME7838E4/E4X Main Components
ME7838E4/E4X Broadband Systems
The ME783A4 Multiport Broadband system consists of the following components:
•MS4647B VNA with Option 007 (Receiver Offset) and Option 08x (Modular Broadband Connection
Capability)
•MN4697C Multiport Test Set
•3736B Broadband Test Set
•3739C Broadband Test Set
•Four 3743E/EX mmWave Modules
•Front and rear panel cables
ME7838E4/E4X Banded Systems
The ME7838E4/E4X Multiport Banded system consists of the following components:
•MS464xB VNA with Option 08x
•MN469xC Multiport Test Set
•3736B Broadband Test Set
•3739C Broadband Test Set
•Four 3744E-EE, 3744E-EW, or four OML/VDI mmWave Modules
•Front and rear panel cables
Caution
A MS464xB VNA unit is heavy. To avoid personal injury, it must be lifted and maneu-
vered by at least two people during installation.
If mounting on a workbench surface, first position the 3739C Broadband Test Set
with access to its front and rear panels. Stack the remaining test sets on top of one
another, then finally the VNA.
If mounting into rack or console, make sure the Test Sets have been installed, and
that the rack/console is carefully positioned on a flat and level surface. If equipped,
make sure any casters are locked. Use two people to lift the VNA unit and two to
guide it into its shelf rails.
The test loops on the front and rear panels of the VNA are delicate. Be careful not to
bump or bend the test loops.

Connect the 3736B and 3739C Broadband Test Set test port cables to the 3743E/EX, 3744E-EE, or 3744E-EW
Modules as shown below, observing the correct torque limits for each connector. See Figure 6 and Table 4.
Route the cable assemblies through the module cable restraint.
Note
It is easier to first connect the cables to the module and then mount the module in its bracket.
Observe torque instructions where indicated. Each module is characterized for a specific VNA Serial
Number and VNA Test Port as designated on the module port assignment label. Ensure the module
matches the correct VNA and Test Set port.
For more detailed information on the modules including DUT Waveguide (WG) connection alignment
and custom bracket mounting, refer to 10410-00311-VectorStar™ Broadband/Banded mmWave
Modules Reference Manual.

Inverting a Module
If necessary, a module can be turned over in the bracket to change the elevation of the W1 connector. To turn
the module over:
1. Remove the six knurled-head thumbscrews from the module.
2. Turn the module over.
3. Install the cable assembly, then install the module into the bracket.
4. Install the six thumbscrews.
mmWave Module Operating Environment
The following notes should be observed when operating the 3743E/EX and 3744E-xx mmWave Modules:
•Thermal heat sinking similar to the supplied mounting brackets of the mmWave Module should be
considered in custom mounting applications.
•Each 3743E/EX Module consumes a maximum of 12 watts.
•Each 3744E-EE and 3744E-EW Module consumes a maximum of 12 watts.
•Each 3744E-Rx Module consumes a maximum of 7 watts.
•The primary heat sink paths for the module is the two side mounting surfaces of the mounting bracket.
•With the attached cable mounting brackets, the case temperature rise is approximately 15 °C to 20 °C
above ambient.
•A three (3) year warranty is valid for all versions of 3744E and 3743E/EX modules, with or without
mounting brackets attached.
