Parameter Description
It is the allowed variation of the target eye width.
It is the eye height to be calibrated.
The filter delay can be enabled on the oscilloscope.
It is the deviation that has occurred in the frequency value.
It is the range of the jitter frequency values 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 is the sequence file to be used during the calibration/test.
It is the number of sync pattern symbols before the data burst. It must be specified in SI (1SI = 10UI).
It is the initial step size value of jitter amplitude.
It refers to the configuration parameters of the BER reader for the system initialization mode with the
parameters such as data channel, data rate and termination mode (Terminated / Unterminated).
It is the amount of ISI (Inter Symbol Interface) added during the test procedure.
It is the amount of ISI (Inter Symbol Interface) added during the test procedure. It is only available for J-BERT
configurations with J20 option.
It is the sequence file for the jitter calibration.
These are the frequency points to be tested/calibrated.
It is the range of the jitter frequency values 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 is the minimum step size value that is used to find the DUT limit for each jitter frequency.
This parameter is available in the Jitter Tolerance test (2.1.7) when the 'Perform Jitter Limit Test" property is
set to true. It defines the windows size of the binary search that is used to find the maximum tolerated jitter.
For M8020A, system configuration is necessary to indicate the termination model such as 50Ohm or 100Ohm.
If the selected mode is not right, the M8020A outputs will be turned off. When the 100 Ohm Termination board
is not available, you can set this parameter to "50 Ohm" and connect SMA cables directly to the scope.
They are pairs of single ended amplitudes (differential and common mode voltage) separated by "|".
These are the frequencies to be tested during Jitter Tolerance Test.
It is the start voltage value to find the target eye height.
It is the maximum value of the interference amplitude to be tested.
It is the higher limit for the tested RF (Radio Frequency) Interference. If the minimum and maximum
interference values are equal, only one interference level is tested.
It is the maximum jitter value to be calibrated.
