Parameter Description
It is the sleep length required by the DUT.
It is a limit value. If the skew between the lanes is below this limit value, the calibration process is ended.
It is the pattern generator sequence for squelch tests.
It defines the STALL state. It specifies the number of DIFN states after the data burst. It must be specified in UI.
It is the STALL time required by the DUT. It has a permitted range of 1 to 255 SI (1SI = 10UI).
It is the number of steps performed between the Minimum and Maximum interference amplitude points.
This is the value to be increased/decreased at each step of the calibration/test procedure.
It defines the length of the SYNC sequence. It has a permitted range of 0 to 15 SI (1SI = 10UI).
It is the range for the SYNC sequence, It can be set as Fine or Coarse.
It is the Activate time required by the DUT to exit the hibernate state and enter into the sleep state.
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.
It is the sequence file used during the test to the DUT.
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.
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.
It isthe frequency deviation relative to the nominal bit rate.
It is the list of common-mode voltage values tested.
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.
It is the total jitter amplitude value.
It is the number of transitions used in each trace calibration.
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".
