Evaluating transmission characteristics of a front end module

6. Setting balance conversion topology

For channel 2, set the balance conversion topology in order to perform measurement
including the balanced port.
Description of setting
Set channel 2 to the active channel.
Set DUT port 1 to unbalance and DUT port 2 to
balance.
Set the destination to which DUT port 1
(unbalance) is connected to test port 1 of the
analyzer.
Set the destination to which DUT port 2
(balance) is connected to test ports 3 and 4 of the
analyzer.
Unbalance-balance conversion for trace 1: ON
Fixture simulator: ON

7. Selecting measurement parameter

Set the measurement parameter for channel 1.
Step 1. Select the measurement parameter for trace 1 of channel 1.
Description of setting
Set channel 1 to the active channel.
Measurement parameter for trace 1: S12
NOTE The subscript of the measurement parameter means the test port of the E5070A/E5071A.
Check the test port assignment and select the measurement parameter.
Step 2. Set the measurement parameter for channels 2, 3, and 4 according to the same procedure as
in Step 1.

8. Executing calibration

Step 1. Display the Ecal menu.
Description of setting
Display the ECal menu.
