ME7838A Broadband System Main Components
The ME783A Multiport Broadband system consists of the following components:
•MS4647A or MS4647B VNA with Option 007 (Receiver Offset) and Option 08x (Modular Broadband
Connection Capability)
•3739B/C Broadband Test Set
•Two 3743A Millimeter-Wave Modules
•Front and rear panel cables
ME7838A Banded System Main Components
The ME7838A Multiport Banded system consists of the following components:
•MS464xA/B VNA with Option 08x
•3739B/C Broadband Test Set
•Two 3744A-EE, 3744A-EW, or two 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.

Millimeter-Wave Module Connections
Connect the 3739B/C Broadband Test Set Port-1 and Port-2 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 4 and
Table 4. Route the cable assemblies through the cable restraint.
Inverting a Module
If necessary, a module can be turned over in the bracket to change the height of the DUT connector. To turn
the module over:
1. Remove the six Knurled Head M2 × 8 mm Thumbscrews from the module.
2. Turn the module over.
3. Install the cable assembly.
4. Install the module into the bracket and then install the thumbscrews.
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 3743A 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.

Millimeter-Wave Module Operating Environment
The following notes should be observed when operating the 3743A and 3744A-xx Millimeter-Wave Modules:
•The modules require use of heatsink with adequate air circulation. Thermal heat sinking similar to the
supplied mounting brackets of the modules 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 sinking path for the module is on the two external side surfaces used to mount to the
support brackets.
•With the attached cable mounting brackets, the case temperature rise is approximately 15 °C to 20 °C
above ambient.
