Fixture Simulator
Example of Using Fixture Simulator
DUT evaluation using the E5070B/E5071B’s fixture simulator
The E5070B/E5071B’s fixture simulator function simulates a test fixture by using internal
software instead of using an actual test fixture for evaluating DUTs.
Figure 7-22 shows an example connection for evaluating a DUT with the
E5070B/E5071B’s fixture simulator function. The unbalanced port of the DUT should be
directly connected to a test port of the E5070B/E5071B, and the balanced port of the DUT
should be connected to two other test ports of the E5070B/E5071B. The actual
measurement by the E5070B/E5071B is performed at single-ended ports with a 50
Ω
port
reference impedance.
Figure 7-22 DUT connection when fixture simulator is used
Figure 7-23 shows the measurement circuit simulated by the fixture simulator based on
actual measurement with the test fixture shown in Figure 7-22.
