Option EXM, External Mixing Upgrade Kit
Add EXT MIXER Connector and Cable to Front Frame Assembly
1. Locate the SMA female to SMA female connector (1250-1666), ¼” lockwasher (2190-0067), and
¼” hex nut (2950-0223) in the kit. If the SMA connector includes hardware, discard that hardware
and use the 2190-0067 lockwasher and 2950-0223 hex nut included in this kit.
2. Remove the hole-plug in the top-most hole in the upper right corner of the front frame assembly.
On newer PXAs, this hole will be labeled “EXT MIXER”. On older PXAs, there will be no label; a
label is included in this kit and will be added later.
3. Insert the SMA female to SMA female connector in the hole in the front frame assembly from the
front of the assembly. The hex feature on the connector should engage with the recess in the front
frame assembly. Refer to Figure 8. Secure the connector using the ¼” lockwasher and ¼” hex nut
from the rear. Torque to 21 inch-pounds.
Figure 8 Attaching SMA Female Connector
4. Locate the External Mixing, Front Panel semi-rigid coax assembly in the kit, part number
N9020-20166. This is W29. Note that this cable is symmetrical; either end can be connected to the
front-panel connector.
5. Connect one end of W29 to the SMA female connector as shown in Figure 10.
6. Orient W29 so that the cable slopes upward from the Ext Mixer connector at a 15 degree angle.
The top of the connector should be approximately level with the top of the shield over the Front
Panel Interface board. Refer to Figure 11. Torque the cable nut on the Ext Mixer connector to 10
inch-pounds.
