Automatic measurement of parameter

Voltage parameters that oscilloscope can

automatically measure include

Maximum value (Vmax) Voltage value from

waveform highest point to GND

ground

Minimum value (Vmin)

Voltage value from

waveform lowest point to GND (ground)

Top value (Vtop): Voltage value from waveform top

to GND (ground)

Base value (Vbase): voltage value from waveform

base to GND (ground)

Middle value (Vmid)

half of amplitude value

Peak peak value (Vpp): voltage value from

waveform highest point to the lowest point

Amplitude value (Vamp): voltage value from

waveform top to bottom

Overshoot: ratio of difference between waveform

maximum value and top value with amplitude value

Preshoot: ratio of difference between waveform

minimum value and bottom value with amplitude

Average value: average amplitude of signal during

a period

Root-mean-square value: the valid value. It means

the converted energy of AC signal in a period is

corresponding to the DC voltage that produces

equivalent energy
