UTD1000 User Manual
Automatic measurement of parameters
Your UTD1000 can automatically measure the following
voltage parameters :
Maximum value (Vmax) : The voltage value from the
highest point to ground (GND) of the waveform.
Minimum value (Vmin) : The voltage value from the
lowest point to ground (GND) of the waveform.
Top value (Vtop) : The voltage value from top to ground
(GND) of the waveform.
Base value (Vbase) : The voltage value from base to
ground (GND) of the waveform.
Middle value (Vmid) : Half of the amplitude value.
Peak-to-peak value (Vpp) : The voltage value from the
highest point to lowest point of the waveform.
Amplitude value (Vamp) : The voltage value from top to
base of the waveform.
Overshoot : The ratio value of the difference between
maximum value and top value to the amplitude value.
Preshoot : The ratio value of the difference between
minimum value and top value to the amplitude value.
Average value : 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 UTD1000 can automatically measure the following
time parameters :
RiseTime : The time taken by the waveform to rise from
10% to 90%.
FallTime : The time taken by the waveform 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.
Rising delay (Rise) : Delayed time of the rising edge
from A to B.
Falling delay (Fall) : Delayed time of the falling edge
from A to B.
Positive duty ratio (+Duty) : Ratio of positive pulse width
to cycle.
Negative duty ratio (-Duty) : Ratio of negative pulse
width to cycle.
