The data generator sends Burst-mode CJTPAT signaling while the DUT is
configured for Terminated-mode.
In Compliance Mode, the data generator sets the calibrated differential
voltage amplitude to the minimum (60mV) and maximum (245mV)
conformance values for the Terminated case. The common mode voltage
is fixed to the nominal value (150mV) according to the specification. No
other signal impairments (ISI or Jitter) are added. At each step, the BER is
measured and compared with the Target BER to consider the pass/fail
result.
In Expert Mode, the differential voltage component of each Level Pair is
tested over the given Amplitude Range. In this case, the result will show
the minimum and maximum differential voltage values at which the DUT
works properly and the test will pass if those values are within the spec
limits.
This test is performed for all selected HS gears and lanes (see
In Unipro Test Mode, with the option "Lane Test Mode" set to
Simultaneously, the different lanes are tested in parallel for each gear.
