measured and compared with the Target BER to consider the pass/fail
result.
In Expert Mode, the common-mode voltage component of each Level Pair
is tested over the given Offset Range. In this case, the result will show the
minimum and maximum offset values at which the DUT works properly and
the test will pass if those values are within the spec limits.
This test is performed at each selected lane.
Refer to the connection diagrams shown in the Connection Diagram
section of the Test 2.1.1- HS-RX Differential Input Voltage Amplitude Test
test.
The parameters used in Expert Mode for this test, are as follows:
•

Settings")
•
CDR Transition Density (if CDR is selected in the Special Parameter
dialog, see
