Keysight N5990A MIPI M-PHY Receiver Test User Guide 275Sys Burst Tests 8490mV and VCM-RX = 330mV for NT); minimum differential voltage andminimum common-mode (VDIF-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 ismeasured and compared with the Target BER to consider the pass/failresult.In Expert Mode, the common-mode voltage component of each Level Pairis tested over the given Offset Range. In this case, the result will show theminimum and maximum offset values at which the DUT works properly andthe test will pass if those values are within the spec limits.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• BerReader Init Mode• Test Sequence• Re-Init sequence after Reset DUT• Lane Under Test Termination Model• Level Pairs• Offset RangeThese parameters are listed in alphabetical order in Table 6.DependenciesThe calibrations required for this test are as follows:
