2. Secure the two bias tee brackets by inserting two screws (item ①, 0515-0372) for each through the test
set deck and the bracket as shown in Figure 1.
3. Position the bias tees on the brackets as shown in item ➁ of Figure 2 on page 12 so that the capacitors
face each other.
4. Secure the bias tees to the brackets using two screws (0515-2994) for each as shown in item ③ of Figure

3. Secure all four attenuators to the brackets using two screws (item
④, 0515-0372) for each.
4. Secure the A46 and A49 receiver attenuators to the test set deck using three screws (item ③, 0515-0372)
for each. Make sure that the attenuators are oriented as shown in the top of the graphic.
5. Secure the A38 and A41 source attenuators to the test set deck using two screws (item ③, 0515-0430) for
each. Make sure that the attenuators are oriented as shown in the top of the graphic.
Step 8.
Install the New Cables
CAUTION
Follow instructions carefully when making cable connections, especially wire harness
connections. Incorrect connections can destroy components, resulting in additional customer

may be necessary but do not over-bend them.
CAUTION
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.
