UTD4000 Four-channel User Manual
Preshoot : The ratio value of the difference between
minimum value and base value to the amplitude
value.
Average : Average amplitude of signals within 1 cycle.
Root mean square value (Vrms) : The effective value.
Energy generated by AC signal conversion during 1
cycle with respect to the DC voltage that produces
equivalent energy, i.e. root mean square value.
Your UTD4000
Series Oscilloscope
can automatically measure the frequency, cycle,
rising time, falling time, positive pulse width, negative
pulse width
delay
positive duty ratio
negative
duty ratio and
time parameters
Definitions of
these parameters are as follows
RiseTime : The time taken by the waveform amplitude
to rise from 10% to 90%.
FallTime : The time taken by the waveform amplitude
to fall from 90% to 10%.
Positive Pulse Width (+Width) : The pulse width when
positive pulse is at 50% amplitude.
Negative Pulse Width (-Width) : The pulse width when
negative pulse is at 50% amplitude.
Delay (Rising or falling edge) : Delayed time from
w a v e f o r m
t o
w a v e f o r m
( d u r i n g

measurement).
Positive duty ratio (+Duty) : Ratio of positive pulse
width to cycle.
Negative duty ratio (-Duty) : Ratio of negative pulse
width to cycle.
