1.ME7838D4 Main Components
ME7838D4 Broadband Systems
The ME7838D4 Multiport Broadbandsystem 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 MA25300A Millimeter-Wave Modules
• Front and rear panel cables
ME7838D4 Banded Systems
The ME7838D4 Multiport Bandedsystem 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
A MS464xA/B VNA unit is heavy. To avoid personal injury, it must be lifted and
maneuvered by at least two people during installation.
Caution
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, 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.
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
Note
matches the correct VNA and Test Set port.
If an alternative MA25300A 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

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 Thumbscrews M2 × 8 mm (four M3 x 8 mm on the MA25300A).
2. Turn the module over
3. Install the cable assembly then install the module into the bracket.

Millimeter-Wave Module Operating Environment
The modules require use of heatsink with adequate air circulation. The following notes should be considered
before operating the MA25300A, 3743x, 3744x-xx, and 3743x-Rx Millimeter-Wave Modules:
• Thermal heat sinking similar to the supplied mounting brackets of the Millimeter-Wave Module should
be considered in custom mounting applications.
• Each MA25300A Module consumes a maximum of 12 watts.
• Each 3743x Module consumes a maximum of 12 watts.
• Each 3744x-EE and 3744x-EW Module consumes a maximum of 12 watts.
• Each 3744x-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.
Connect the front panel cables between the 3736B and 3739C Test Sets, and the OML or VDI frequency
extension modules as shown in Figure 8, Figure 9, and Figure 10, and as described in Table 6, Table 7, and
Table 8.
CautionTo avoid connector damage, observe torque requirements where indicated.
