Measurement Description
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 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 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 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 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 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.
Positive Pulse Width The distance (time) between the mid reference (default 50%) amplitude points of a positive pulse.
The measurement is made on the first pulse in the measurement region.
Rise Time The time required for the leading edge of the first pulse in the measurement region to rise from the low
reference value (default = 10%) to the high reference value (default = 90%).
The measurement is taken on each cycle of the waveform record.
Rising Slew Rate The rate of change (in volts/second) as an edge transitions from a low reference level to a high
reference level.
The measurement is taken on each cycle of the record in the measurement region.
Setup Time The time between the specified Mid reference level crossing on the data signal to the closest Mid
reference level crossing on the specified clock signal.
The measurement is made on each specified clock edge in the waveform record.
Skew The time between the specified Mid reference level crossing on one source to the closest Mid
reference level crossing on the second source signal.
The measurement is made on each cycle in the waveform record.
Time Outside Level The time the specified signal remains above the Top reference level and/or below the Base reference
level.
The measurement is made on each occurrence in the waveform record.
Time to Min Time to Min is the amount of time from the trigger point to the minimum data point. This measurement
can be made across the entire record or on each cycle in the record.
Time to Max Time to Max is the amount of time from the trigger point to the maximum data point. This measurement
can be made across the entire record or on each cycle in the record.
