Keysight N5990A MIPI M-PHY Receiver Test User Guide 261PWM Tests 7ProcedureThe data generator sends Burst-mode CJTPAT signaling with nominalamplitude settings while the DUT is configured for Terminated-mode orNon-Terminated-mode depending on the test case.The TOL PWM-G1-LR-RX is the ratio of the PWM Receive Bit Duration(TPWM-RX) and the average of N PWM receive bit durations duringLINE-READ in PWM-G1. The TOLPWM-G1-LR-RX is tested for theconformance limit values (0.89/1.01) and for the given Additional Steps. Ateach step, the BER is measured and compared with the Target BER toconsider the pass/fail result.This test is performed at each selected lane and PWM gear.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• Min Tested• Max Tested• Additional Steps• SequenceThese parameters are listed in alphabetical order in Table 6.
