3 Calibrations and Test Procedures
Sleep Time Capability It is the sleep length required by the DUT.
Skew Tolerance It is a limit value. If the skew between the lanes is below this limit value, the calibration process is ended.
Squelch Test Sequence It is the pattern generator sequence for squelch tests.
Stall Length It defines the STALL state. It specifies the number of DIFN states after the data burst. It must be specified in UI.
Stall Time Capability It is the STALL time required by the DUT. It has a permitted range of 1 to 255 SI (1SI = 10UI).
Steps Interference Amplitude It is the number of steps performed between the Minimum and Maximum interference amplitude points.
Step Size This is the value to be increased/decreased at each step of the calibration/test procedure.
(HS / LS) Sync length It defines the length of the SYNC sequence. It has a permitted range of 0 to 15 SI (1SI = 10UI).
(HS / LS) Sync range It is the range for the SYNC sequence, It can be set as Fine or Coarse.
T Activate capability It is the Activate time required by the DUT to exit the hibernate state and enter into the sleep state.
Target BER The default target BER value is 1E-10 and if the measured BER is smaller than the target value, the test is
considered as passed.
Test Sequence It is the sequence file used during the test to the DUT.
Tested Accumulated Differential
Voltage It is the accumulated differential voltage value to be tested. The differential voltage amplitude is set
according to the calibration in order to match the desired accumulated differential voltage.
Tested Accumulated Differential
Range It is the accumulated differential voltage range to be tested. It is defined with four values separated by
semicolons: <Start Value>;<End Value>;<Number of Steps>;<Scale Type>. The scale type can be Linear or
Logarithmic.
Tested Frequency Offset It isthe frequency deviation relative to the nominal bit rate.
Tested Offset It is the list of common-mode voltage values tested.
Tested Range It is the range used to test the frequency offset value. It is defined with four values separated by semicolons:
<Start Value>;<End Value>;<Number of Steps>;<Scale Type>. The scale type can be Linear or Logarithmic.
Total Jitter It is the total jitter amplitude value.
Transitions It is the number of transitions used in each trace calibration.
Use Infiniisim
Transfer Function Chan1
Transfer Function Chan2 The parameter, “Use Infiniisim” can be set to “True” or “False”. When a replica channel is not available or you
want to use the Infiniisim Transfer Function instead of a replica channel, set the “Use InfiniiSim” parameter to
“True” and copy the Transfer Function file to the scope, either under “C:\Users\Public\Public Documents\
Infiniium\Filters\M-PHY” or “C\Documents and Settings\All Users\Documents\Infiniium\Filters\M-PHY”.
