Test Mode 4. Transmitter Distortion and MDI Return Loss Tests
Test Setup
Sections 1 and 11 of the N5395C Ethernet Test Fixture are used in this test.
A disturbing signal source is required to test for compliance. There is an option to
test without a disturbing signal source, but the test result is not applicable for
compliance. The test accepts only a differential signal.
When using a supported function generator, there is an automatic calibration
process to calibrate the function generators. If an unsupported model is used, the
user will have to manually calibrate the function generators.
