64 UTD1000L User Manual
Middle Value (Vmid): a half of amplitude value
Peak-to-Peak Value (Vpp): Voltage measured from the highest point to the lowest point of
waveform
Amplitude (Vamp): Votage measured from the top to the base of the waveform
Overshoot: (Maxi-Top)/Amplitudex100%
Preshoot: (Min-Low)/Amplitudex100%
Average Value: The arithmetic mean over one cycle in the waveform
RMS Value (Vrms): Effective value, the root mean square voltage over one cycle in AC signal
waveform that corresponds toDC voltage with equal generated energy calculated in this cycle.
Figure 6-21 Time Measurement
The time parameters the Oscilloscope can automatically measure contain:
RiseTime: The time required to rise from 10% to 90% of waveform amplitude.
FallTime: The time required to fall from 90% to 10% of waveform amplitude.
Positive Pulse Width (+Width):
The distance between the mid (50%) amplitude points of a positive pulse.
Negative Pulse Width (-Width):
The distance between the mid (50%) amplitude points of a negative pulse.
Rising Delay: The delay time between rising edges from A to B
Falling Delay: The delay time between falling edges from A to B
Positive Duty Cycle (+Duty): the ratio of positive pulse width to the period.
Negative Duty Cycle (-Duty): the ratio of negative pulse width to the period.
