On this web page, you can select various tabs for more information about your instrument. Included is a
“Library” tab which contains links to all the latest technical documentation related to this instrument.
1. ME7838A4 Main Components
ME7838A4 Broadband Systems
The ME7838A4 Multiport Broadband system consists of the following components:
•MS4647A or 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 3743A Millimeter-Wave Modules
•Front and rear panel cables
ME7838A4 Banded Systems
The ME7838A4 Multiport Banded system consists of the following components:
•MS464xA/B VNA with Option 08x
•MN4694C Multiport Test Set
•3736B Broadband Test Set
•3739C Broadband Test Set
•Four 3744A-EE, 3744A-EW, or four OML/VDI Millimeter-Wave Modules
•Front and rear panel cables
Caution
A MS464xA/B VNA unit is heavy. To avoid personal injury, it must be lifted and
maneuvered 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.

6. Front Panel to Millimeter-Wave Module Connections
Connect the 3736B and 3739C Broadband Test Set test port cables to the 3743A, 3744A-EE, 3744A-EW, or
3744A-Rx Modules as shown below, observing the correct torque limits for each connector. See Figure 7 and
Table 5. Route the cable assemblies through the module cable restraint.
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 six thumbscrews.
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 (except the 3744A-Rx) 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 Millime-
ter-Wave Modules Reference Manual.

Millimeter-Wave Module Operating Environment
The following notes should be observed when operating the 3743A and 3744A-xx mm-Wave Modules:
•Thermal heat sinking similar to the supplied mounting brackets of the Millimeter-Wave Module should
be considered in custom mounting applications.
•Each 3743A Module consumes a maximum of 12 watts.
•Each 3744A-EE and 3744A-EW Module consumes a maximum of 12 watts.
•Each 3744A-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 3744A and 3743A modules, with or without
mounting brackets attached.
