DCD + ISI LPF - This option applies a Low Pass Filter to the DCD+ISI data. The resulting, filtered data is plotted on
top of the raw DCD+ISI data in the DCD+ISI vs. Edge plot window. This feature allows the modeling of receiver
performance given the measured (transmitted) data pattern if the characteristics of the receiver are known.
DCD + ISI Patterns - Enter number of pattern intervals for which measurements will be taken. Defaults to 1 for
compliance testing. Increase this value to see more pattern repeats on the dataCOM with Marker, DCD + ISI vs.
Edge View (see figure below). Note: Bit Rate Patterns should be set greater than or equal to DCD + ISI Patterns
because an accurate bit rate is important for calculating the ideal unit interval; DCD + ISI is calculated as a deviation
from this ideal UI.
