1. Using the Torque Wrench Using the torque wrench guarantees that a connection is not too tight This will help prevent possible connector damage It also guarantees that all connections are equally tight each time 1 Static friction must not be present during torquing 2 Do not pre tighten so much that there is no rotation of the nut with the torque wrench Leave about 1 8 turn or 45 degrees of rotation for the final tightening with the torque wrench 3 Rotate only the connector nut when you tighten the connector Use an open end wrench to keep the body of the device from turning Table 4 1 provides information on the torque wrench required for making 1 0 mm connections and for the threading the launch into the package wall Refer to Table 5 1 on page 5 1 for ordering information and part numbers Table 4 1 Torque Wrench Information Connector Torque Torque Backup Type Setting Tolerance Wrench 1 0 mm 45 N cm 4 in lb 25 4 N cm 0 5 in Ib 6 mm 7 mm Launch installation 56 N cm 5 in lb 25 4 N cm 0 5 in Ib To thread the launch into the package wall use a 7 mm torque wrench on the hex portion of the launch and tighten the launch into the package wall with 56 N cm 5 in Ib of torque To make 1 0 mm connections to the launch use a 6 mm torque wrench to apply the recommended torque to the 1 0 mm male nut while holding the hex portion of the launch with a 7 mm open end backup wrench To make other 1 0 mm conn2. 1 Not available from Keysight Technologies This part number may be ordered from Mountz San Jose CA Keysight Technologies 11923A Launch Assembly Operating and Service Manual 5 1 Replaceable Parts 5 2 Keysight Technologies 11923A Launch Assembly Operating and Service Manual Index A assembling the package wall 3 1 C center conductor protrusion and pin depth 2 1 characteristics supplemental mechanical 2 1 completing the signal path 3 3 connections alignment 4 6 process 4 9 connector contacts 4 3 connectors clarifying sex 1 2 cleaning 4 8 damaged 4 4 defects or damage 4 2 mating plane surface 4 4 damaged connectors 4 4 disconnection procedure 4 11 E electrostatic discharge 4 1 environmental requirements 2 1 F figure adapter dimensions 2 1 alignment 4 7 circuit mounting detail 3 3 cleaning illustration 4 8 concentricity female connector 4 3 concentricity male connector 4 4 connector pin depth 4 5 contact integrity 4 3 machining detail for mounting the launch 3 1 male and female connectors 1 2 misalignment 4 7 H handling and storage 4 12 insertion loss 2 1 inspection incoming 1 2 visual 4 2 L launch creating the package wall 3 1 overview 1 1 M maintenance preventive 4 1 making connections 4 1 mating plane surfaces 4 4 mounting the circuit 3 2 mounting the launch 3 1 P package wall assembly instructions 3 1 machinin
