d.
Port 1 LO. Tighten and torque as above.
e.
Power 1 Power and Signal. Fasten in place with two screws.
f.
Route the other end of the cable assembly to the Port 1 Module location.
16.
Connect the phase-stable cable to the VNA Test Port 1. Thread, tighten, and torque as above. Route the
other end of the cable assembly to the Port 1 Module location.
Port 2 Cable Connections to VNA and Test Set
17.
Connect the Port 2 to Module Port 2 Cable Assembly to the Test Set. Note that each cable is clearly
labeled:
a.
Port 2 Test. Tighten and torque as above.
b.
Port 2 Ref. Tighten and torque as above.
c.
Port 2 RF. Tighten and torque as above.
d.
Port 2 LO. Tighten and torque as above.
e.
Power 2 Power and Signal. Fasten in place with two screws.
f.
Route the other end of the cable assembly to the Port 2 Module location.
18.
Connect the phase-stable cable to the VNA Test Port 2. Thread, tighten, and torque as above. Route the
other end of the cable assembly to the Port 2 Module location.
19.
Place the modules into position, observing the correct module-to-port configuration.
20.
If the modules were removed from their brackets (either the factory original or a user-defined), install
them in the bracket, observing which side of the module is up.
•
The factory as-shipped orientation is with the
RF
,
SRC
, and
LO
connectors and the
W1
connector
closest to the bracket. The procedure steps below assume the factory as-shipped orientation.
•
If the module orientation has been changed, the general recommendation is to install the cables
and connectors closest to the bracket first.
Port 1 Module Connections
21.
Connect the
SRC
cable to the Port 1 Module. Align, thread, tighten, and then use an 8 mm (5/16”) torque
end wrench and torque to 0.9 N·m (8 lbf·in), for 3743A Millimeter-Wave Module only.
22.
Connect the
RF
cable to the Port 1 Module. Thread and tighten as above.
23.
Connect the
LO
cable to the Port 1 Module. Thread, tighten, and torque as above.
24.
Connect the
REF
cable to the Port 1 Module. Insert, thread carefully, and gently tighten the SSMC
connector. Tighten using a 4 mm (5/32”) end wrench.
25.
Connect the
TEST
cable to the Port 1 Module. Thread and tighten the SSMC connector as above.
26.
Carefully, observing the connector polarity, match up the markings on the
Power/Signal
plug with the
power/signal connector. The connector snaps into place.
Port 2 Module Connections
27.
Following the same sequence as the sub-section above, connect the cables to the Port 2 Module.
a. SRC
b. RF
c. LO
d. REF
e. TEST
f.
Power/Signal
