Keysight N5990A MIPI M-PHY Receiver Test User Guide 223Squelch Tests 6When using UniPro Test Mode, the observable is that the DUT gets intoTest Mode and starts sending FILLER symbols back.The measured value of TSQ must be less than or equal to T_Activate inorder to be considered conformant.Connection DiagramRefer to the connection diagrams shown in the Connection Diagramsection of the Test 2.4.3-SQ-RX Squelch Exit Voltage (VSQ) test.ParametersThe parameters used in Expert Mode for this test, are as follows:• Data Rate• CDR Loop Bandwidth (if CDR is select in Special Parameter dialog, see“BERT Analyzer Settings”)• CDR Peaking (if CDR is select in Special Parameter dialog, see “BERTAnalyzer Settings”)• CDR Transition Density (if CDR is select in Special Parameter dialog,see “BERT Analyzer Settings”)• CDR Loop Order (if CDR is select in Special Parameter dialog, see“BERT Analyzer Settings”)• Target BER• IBerReader Init Mode• Squelch Test Sequence• Re-Init sequence after Reset DUT• T Activate capability• Min Value• Max Value• Step Size• Set Single ended Amplitude• Tested Offsets• Number of Pulses• Pulse Distance• Pulse WidthThese parameters are listed in alphabetical order in Table 6.
