Timing measurement algorithms
Burst Width measurement algorithm
Burst Width is the duration of a series of adjacent crossings of the mid reference level. The duration of a burst. Bursts are
separated by a user-defined idle time.
Data Rate measurement algorithm
Data Rate is the reciprocal of Unit Interval. This measurement is made on each bit in the record.
Delay measurement algorithm
Delay is the time between a mid reference level edge on one source to a mid reference level edge on a second source. The
direction of each edge can be configured by the user.
Falling slew rate
Falling Slew Rate is the rate of change in value as an edge transitions from the high or mid reference level to the mid or low
reference level. The levels are configurable.
In the diagram below, the Falling Slew Rate from mid ref to low ref is calculated using the following equation:
Falling Slew Rate = (VREF - VREFLO)/ΔTF
Fall Time measurement algorithm
Fall Time is the time required for an edge to fall from the high reference level to the low reference level. By default the
measurement is from reference level 90% amplitude to 10% amplitude.
