A103 – ND75884<R> or 3-ND75884<R> RF Amplifier Module
The A103 RF Amplifier Module connects between the Front Panel VNA RF Input Connector and the A104
SPDT Switch. The replacement module comes with a soldered-on cable harness that connects to A1 PCB
Connector P1.
1 – Disconnect the module power cable from P1 at A1
PCB.
2 – Remove the two (2) M3 x 0.5 x 8 mm module
mounting screws.
3 – Disconnect the semi-rigid cable coupling nut from
A104 switch input J1.
4 – Disconnect the semi-rigid cable coupling nut from the
front panel VNA RF input connector.
5 – Remove the module with semi-rigid cables attached.
6 – Transfer the semi-rigid cables to J1 and J2 of the new
A103 module but do not tighten the coupling nuts.
7 – Install the assembly then align and connect the
coupling nuts to A104 and front panel RF but do not
tighten.
8 – Install the two (2) module mounting screws finger
tight; do not tighten yet.
9 – Torque each coupling nut to 0.9 N·m (8 lbf·in) using
two 8 mm (5/16”) wrenches using one to hold the
connector body and the other to torque the cable nut.
10 – Tighten the two (2) module mounting screws.
11 – Connect the module power cable to connector P1 at
