ME7838A/AX Broadband System Main Components

The ME7838A/AX 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/AX mmWave Modules

•Front and rear panel cables

ME7838A/AX Banded System Main Components

The ME7838A/AX 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 mmWave 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 3739B/C 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.

VectorStar ME7838A/AX QSG PN: 10410-00292 Rev. F QSG-9

mmWave Module Connections

Connect the 3739B/C Broadband Test Set Port-1 and Port-2 cables to the 3743A/AX, 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/AX mmWave 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 the VectorStar Broadband/Banded mmWave Modules

Reference Manual – 10410-00311.

mmWave Module Operating Environment

The following notes should be observed when operating the 3743A/AX and 3744A-xx mmWave 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/AX 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.
