b. Mount the cable holder (attached to the 7-mm coaxial connector module of the
Heat-Resistant Cable) on the Fixture Stand with its captive screws.
c. Place the Fixture Stand on a box (a carton or a substitute) to level the Heat-Resistant
Cable at the same hight as the DUT Port on the test head. Adjust the hight of the
Fixture Stand for 223 mm  10 mm with a spacer (another carton or books) inserted
between the Fixture Stand and box as shown in the figure.
d. Connect the 1 meter RF Extension Cable Assembly and Heat-Resistant Cable to the test
head of the E4991A as shown in the figure.
CAUTION Do not force the RF extension cable assembly. It is strongly suggested that the RF
extension cable assembly be connected last of the setup procedure in order to prevent the
joint of SMA connectors on the cable from being forced and damaged.
CAUTION Do not force the high temperature cable or else the cable may be impaired. Avoid bending
the cable.

Step 3. Connect the test equipment to the 7-mm coaxial connector on the high temperature cable
assembly in place of the DUT Port on the test head and, perform the following tests. See
Figure 2-13 for the connector to which the test equipment (a power sensor, coaxial
terminations or a 10 cm air-line) is connected.
• Power Level Accuracy Test
• Impedance Measurement Accuracy Test
NOTE Record the test results using the performance test record for Option 007.
