N5392A Ethernet compliance test with N5392-66404 (N5395B) test fixture

Hi,

I am trying to run some tests on a 10/100 interface with a link partner, but I cannot establish a link through the test fixture using section 6 of the fixture. I think I have the connections correct, as there are only two Ethernet ports within section 6.

Are there any tests I can run on the test fixture itself to check to see if it is damaged? Without being able to signal through the board there is no way to establish a link with the link partner so at this point I am dead in the water.

Thanks,

Jeff

  I have problem of using this test fixture with link partner too. It seems that the Rx path of the fixture for DUT has 2K resistors on each wire of the differential pair which blocks the Ethernet signal. You may be OK to run Ethernet compliance test if you can force the Ethernet PHY to send signal out on Tx pair.

  Hi ksmith.
  
  I received DSO9000 series this week and tried the fixture.
  
  It can not link with partner.
  
  Can you share with me the countermeasure?
  
  Thank you
