The data generator sends Burst-mode CJTPAT signaling while the DUT is
configured for Terminated-mode. In Compliance Mode, the differential
voltage amplitude and the common-mode are set to the nominal values
(200mV). In Expert Mode, two Level Pairs are tested, the differential
voltage amplitude is set to the minimum (60mV) and maximum (245mV)
conformance values while the common-mode is kept to the nominal value
(150mV). It must be performed using the maximum f
ppm. No other signal impairments such as the ISI channel or the jitter
sources are added to the signal.
The duration of HS-Sync Length (T
(symbol interval), where 1 SI = 10 HS and its value is calculated as given in
Table
32. This T
(see
Figure
122). At each step, the BER is measured and compared with
the Target BER to consider the pass/fail result. The DUT must be able to
successfully receive bursts whose sync length is greater than or equal to
the RX_HS_Gx_SYNC_LENGTH_Capability attribute.
This test is performed for all selected HS lanes and gears. It is only
required for the Terminated case. In Unipro Test Mode, with the option
"Lane Test Mode" set to Simultaneously, the different lanes are tested in
parallel for each gear.
