Measurement Description
Burst Width
2
The duration of a series of adjacent crossings of the Mid reference level. Bursts are separated
by a specified idle time.
The measurement is taken on each burst in a waveform record.
Data Rate
2
Data Rate is the reciprocal of Unit Interval.
The measurement is taken on each bit of the waveform record.
Delay
The time difference between the mid reference (default 50%) amplitude point of two different
waveforms. You can specify the signal edges to measure in the measurement’s Configuration
menu.
The measurement requires two sources.
Duration N-Periods
2
The time required to complete N cycles. A cycle is the time between two adjacent (same
direction) crossings of the mid reference level.
The measurement is taken on each cycle in the waveform record.
Fall Time The time required for the trailing edge of the first pulse in the measurement region to fall from
the high reference value (default = 90%) to the low reference value (default = 10%).
The measurement is taken on each cycle of the waveform record.
Falling Slew Rate The rate of change (in volts/second) as an edge transitions from a high reference level to a low
reference level.
The measurement is taken on each cycle of the record in the measurement region.
Frequency
2
The frequency of the waveform. Frequency is the reciprocal of Period (Frequency = 1/Period).
High Time
The time the signal remains above the Top reference level.
The measurement is taken on each cycle in the waveform record.
Hold Time
2
The time between the specified Mid reference level crossing on the clock signal to the closest
Mid reference level crossing on the specified data signal.
The measurement is taken on each specified clock edge in the waveform record.
Low Time The time the signal remains below the Base reference level.
The measurement is taken on each cycle in the waveform record.
Negative Duty Cycle
2
The ratio of the negative pulse width to the signal period, expressed as a percentage.
The duty cycle is measured on the first cycle in the measurement region.
Negative Pulse Width
2
The distance (time) between the mid reference (default 50%) amplitude points of a negative
pulse.
The measurement is taken on each cycle in the waveform record or measurement region.
Period
2
The time between two adjacent crossings of the Mid reference level (one cycle) of the
waveform.
The measurement is taken on each cycle of the waveform record or measurement region.
Phase
2
The time difference (phase shift) between the specified signal edges of waveform source 1 and
waveform source 2. The measurement is expressed in degrees, where 360° comprise one
waveform cycle. This measurement requires two sources.
The measurement is taken on each cycle of the waveform record.
Positive Duty Cycle
2
The ratio of the positive pulse width to the signal period, expressed as a percentage.
The duty cycle is measured on the first cycle in the measurement region.
2
This measurement can also be taken on digital signals.
