Keysight N5990A MIPI M-PHY Receiver Test User Guide 271Sys Burst Tests 8In Compliance Mode, the data generator sets the calibrated differentialvoltage amplitude to the minimum (60mV for RT, 120mV for NT) andmaximum (245mV for RT, 490mV for NT) conformance values. Thecommon mode voltage is fixed to the nominal value (150mV) according tothe specification. No other signal impairments (ISI or jitter) are added.At each step, the BER is measured and compared with the Target BER toconsider the pass/fail result.In Expert Mode, the differential voltage component of each Level Pair istested over the given Amplitude Range. In this case, the result will showthe minimum and maximum differential voltage values at which the DUTworks properly and the test will pass if those values are within the speclimits.This test is performed at each selected lane.Connection DiagramRefer to the connection diagrams shown in the Connection Diagramsection of the Test 2.1.1- HS-RX Differential Input Voltage Amplitude Testtest.ParametersThe parameters used in Expert Mode for this test, are as follows:• CDR Loop Bandwidth (if CDR is selected in the Special Parameterdialog, see “BERT Analyzer Settings”)• CDR Peaking (if CDR is selected in the Special Parameter dialog, see“BERT Analyzer Settings”)• CDR Transition Density (if CDR is selected in the Special Parameterdialog, see “BERT Analyzer Settings”)• CDR Loop Order (if CDR is selected in the Special Parameter dialog,see “BERT Analyzer Settings”)• Target BER• IBerReader Init Mode• Test Sequence• Re-Init sequence after Reset DUT• Lane Under Test Termination Model• Level Pairs• Amplitude RangeThese parameters are listed in alphabetical order in Table 6.
