6 Millimeter-Wave Connections Connect the 3739B/C Broadband Set Port-1 and Port-2 cables to the 3743E, 3744E-EE, 3744E-EW, or 3744E-Rx s as shown below, observing the correct torque limits for each connector. See Figure 3 and Table 3. 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 3744E-Rx) is characterized for absolute power for a specific VNA Serial Number and VNA Port as designated on the module port assignment label. Ensure the module matches the correct VNA and Set port. If an alternative 3743E mm-wave module is used there will be approximately 1 db of absolute power inaccuracy which can be corrected by performing a power calibration.

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. QSG- PN: Rev. B VectorStar ME7838E QSG

Cable 80-2xx Coaxial Phase Stable Cable is used only with the 3743E module. Millimeter-Wave Operating Environment The following notes should be observed when operating the 3743E and 3744E-xx Millimeter-Wave s: Thermal heat sinking similar to the supplied mounting brackets of the Millimeter-Wave should be considered in custom mounting applications. Each 3743E consumes a maximum of 12 watts. Each 3744E-EE and 3744E-EW consumes a maximum of 12 watts. Each 3744E-Rx 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 1 C to 20 C above ambient. VectorStar ME7838E QSG PN: Rev. B QSG-7
