ME7838G4 Banded Systems
The ME7838G4 Multiport Banded system consists of the following components:
•MS464xB VNA with Option 08x
•MN4694C Multiport Test Set
•3736B Broadband Test Set

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 3739C Broadband Test Set Port-1 and Port-2 cables to the MA25300A, MA25400A, 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 cable restraint.
Note
For ease of connection, the module can be removed from the bracket, then reinstalled after cables
are secured. Observe torque instructions where indicated.
Each module (except the 3744A-Rx) is characterized for absolute power 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.
If an alternative MA25300A, MA25400A, or 3743 series mm-Wave module is used there will be
approximately 1 dB of absolute power inaccuracy, which can be corrected by performing a power
calibration.
For more detailed information on the modules including DUT Waveguide (WG) connection alignment
and custom bracket mounting, refer to 10410-00311 – VectorStar Broadband/Banded
Millimeter-Wave Modules Reference Manual.
