What are the definitions of the Oscilloscope's measurements?

Frequency
Frequency of the signal as determined by the time between rising or falling edges

 

Period
Time between pairs of rising or falling edges

 

Duty Cycle
Ratio of the time spent above the median to that spent below it

 

Pulse Width
Time the signal spends above the median

 

Negative Width
Time the signal spends below the median

 

Mean
Average value of the signal

 

RMS
Root-Mean-Square value of the signal

 

Cycle Mean
Average value of the signal, discounting partial cycles at the beginning and end of the frame

 

Cycle RMS
Root-Mean-Square value of the signal, discounting partial cycles at the beginning and edge of the frame

 

Standard Deviation
Mathematical description of the spread of the points in the signal

 

Peak to Peak
Difference between the highest and lowest voltage in the signal

 

Amplitude
Difference between the high- and low-level voltage, excluding over- and undershoot

 

Maximum
Highest voltage in the signal

 

Minimum
Lowest voltage in the signal

 

High Level
Highest voltage in the signal, excluding overshoot

 

Low Level
Lowest voltage in the signal, excluding undershoot

 

Rise Time
Time taken for the signal to transition from 10% to 90% of the way from minimum to maximum

 

Fall Time
Time taken for the signal to transition from 90% down to 10% of the way from maximum to minimum

 

Rise Rate
Rate at which the signal transitions from 10% to 90% of the way from minimum to maximum

 

Fall Rate
Rate at which the signal transitions from 90% to 10% of the way from maximum to minimum

 

Overshoot
Distance the signal shoots above the maximum level before settling

 

Undershoot
Distance the signal shoots below minimum level before settling
