Automatic measurement of voltage parameters
Voltage parameters which can be measured by
UTD2000/3000 series oscillograph automatically
are as follows:
Peak value (Vpp): Voltage from the highest
waveform point to the lowest waveform point;
The maximum value (Vmax): Voltage from the
highest waveform point to GND (ground);
The minimum value (Vmin): Voltage from the lowest
waveform point to GND (ground);
Middle value (Vmid): Half of sum of waveform top
and bottom voltage;
Amplitude (Vamp): Voltage from waveform top to
bottom;
Middle value (Vmid): Half of sum of waveform top
and bottom voltage;
Top value (Vtop): Voltage from flat waveform top to
GND (ground);
Bottom value (Vbase): Voltage from waveform
bottom to GND (ground);
Overshoot: Ratio of difference of the maximum
waveform value and top value and amplitude;
Preshoot: Ratio of difference of the minimum
waveform value and bottom value and amplitude;
Average value: Average amplitude of signals within
a cycle;
Root-mean-square (Vrms): It is effective value.
Root-mean-square refers to DC voltage of
converted energy within 1 cycle according to AC
signal to correspond to equivalent energy.
