Connect the system bus cable from the HP85148 (or 8512A) J12 8510 SYSTEM BUS connector to the
8510
of the HP85101 display/processor. The test set IF interconnect cable
and the system bus cable transmit control signals between the test set and the network analyzer.
Signal Path Connections.
The IF signals from the test set are transmitted to the HP 85102 IF Detector
by the test set IF interconnect cable (see above).
RF signals are transmitted from the source to the test set by the 3.5 mm flexible RF cable supplied with
the test set. Recommended torque is 56 N-cm
for the RF cable-to-test-set/RF input connection.
Anti-Rotation Clamps.
only) Use these clamps to stabilize the test port/RF cable connec-
tion. Connect the test port cables to the test ports and tighten them as specified in the cable manual.
Loosen the anti-rotation clamp thumb screw sufficiently to slip the clamp over the cable and up to the
front panel. The clamp end with the flats should come to rest on the flats of the test port shoulder. Finger
tighten the thumb screws to prevent further loosening or tightening of the test port/RF cable connec-
tion.
The internal O-ring is field replaceable without disassembling the anti-rotation clamp. Pry it out with fine
tweezers or a similar tool when it no longer holds the RF cable securely. Insert the new O-ring by
engaging one side of it in the slot of the phenolic clamp donut. Use your fingers to push the O-ring into
the rest of the slot.
The HP part number of the O-ring is 0900-0007 (CD 7).
If reshipping is required, each test set should be repackaged in the original factory package. Con-
tainers and materials identical to those used by the factory are available through Hewlett-Packard
offices.
Alternatively, comparable packaging materials may be used. Wrap the test set in heavy paper or anti-
static plastic. If shipping to an HP Office or Service Center, complete and attach a service tag (in the
HP 8510 manual set). Use sufficient shock absorbing material on all sides of the test set to provide a
thick, firm cushion and prevent movement. Seal the shipping container securely and mark it
FRAGILE.
In any correspondence with HP, refer to the test set by full model and serial number.
