For all analyzer serial numbers
- W135(N5242-20278) Front-panel Port 2 RCVR B IN to A45 port 2
receiver attenuator
- W129(N5242-20293) A53 port 2 bypass switch to A54 port 2 bridge
- W128(N5242-20303) A53 port 2 bypass switch to front-panel Port 2

- W130(N5242-20302) A53 port 2 bypass switch to A54 port 2 bridge
Follow instructions carefully when making cable connections, especially
wire harness connections. Incorrect connections can destroy components,
resulting in additional customer costs.
Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
Use a 5/16-in torque wrench set to 10 in-lbs on all cable connections
except the front and rear panel bulkhead connectors. On these, use a 9
mm nutsetter or open end torque wrench set to 21 in-lb.
Some of these cables may have different dimensions from those shown in
the graphics.
