Test Mode 4. Transmitter Distortion and MDI Return Loss
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.
Only the Keysight 81150A Function Generator is supported in this test.
