7. Fixture Simulator
Evaluating Balanced Devices (balance-unbalance conversion
function)
The balance-unbalance conversion function simulates a measurement under a balanced
state based on measurement results obtained in an unbalanced state (
Figure 7-7). This
function enables you to evaluate devices with balanced ports.
NOTE Be sure to set the impedances of the two unbalanced ports equal to each other. For more
details on setting up port impedance for unbalanced ports, refer to
“Converting the Port
Impedance of the Measurement Result” on page 286.
Figure 7-7 Balance-unbalance conversion
The types of devices that can be evaluated using the E5070B/E5071B are shown in Figure
7-8.
NOTE To evaluate a balanced device, an E5070B/E5071B with at least three test ports (option
313, 314, 413, or 414) is required.
