Parameters in Expert Mode
• Number of Allowed Frame Errors: The number of frame errors that are
allowed. The default value is '0'.
• Number of Frames: The number of frames used for frame error
measurement.
• Search Algorithm: Select how the test searches for the fail point for
each frequency.
• Frequency Mode: It can be selected as:
• Compliance Frequencies
• Equally Spaced Frequencies
• User Defined Frequencies
• Single Frequency
• If Compliance Frequencies, User Defined Frequencies or Single
Frequency is chosen:
• Jitter frequencies: List of frequencies to be tested. If compliance
mode, they are read-only, otherwise they can be edited.
If Equally Spaced Frequencies are selected:
• Start frequency value: This is the minimum value of jitter frequency
to be tested.
• Stop frequency value: This is the maximum value of jitter frequency
to be tested.
• Number of Frequency Steps: The number of different jitter
frequencies that are tested. The distribution of frequencies between
minimum and maximum is equidistant on a logarithmic scale.
• Frequency sweep scale: This can be chosen as Linear or
Logarithmic.
• Start jitter amplitude: This is the initial value of the SJ amplitude tested
in the search algorithm.
• Use fixed number of steps: The range of jitter amplitudes to be tested at
each frequency starts with the defined “Start jitter amplitude” and ends
with the jitter capability of the data generator. If this parameter is True,
the range is divided in a fixed number of steps. If it is False, the steps
are defined by the step size.
• Number of jitter steps: The number of jitter points used in the search
algorithm
