490mV and V
CM-RX
= 330mV for NT); minimum differential voltage and
minimum common-mode (V
DIF-RX
= 60mV and V
CM-RX
= 25mV for RT,
V
DIF-RX
= 120mV and V
CM-RX
= 25mV for NT). At each step, the BER is
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.
Connection Diagram
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.
