Keysight N5990A MIPI M-PHY Receiver Test User Guide 193
HS Tests 5
Procedure
This test is similar to the previous Test 2.1.8 but in this case, the data
generator sends Continuous-Mode CJTPAT signaling instead of
Burst-Mode, and the DUT is configured to receive the Continuous-Mode
CJTPAT in Terminated mode. For more details refer to the Procedure
section of the Test 2.1.8-HS-RX Frequency Offset Tolerance (fOFFSET-RX)
during HS Burst).
Connection Diagram
Refer to the connection diagrams shown in the Connection Diagram
section of the Test 2.1.1- HS-RX Differential Input Voltage Amplitude Test.
Parameters
The parameters used in Expert Mode for this test, are as follows:
• CDR Loop Bandwidth (if CDR is selected in the Special Parameter

• 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 Parameter
dialog, see “BERT Analyzer Settings” )
• CDR Loop Order (if CDR is selected in the Special Parameter dialog,
see “BERT Analyzer Settings” )
• Target BER
