 Voltage Parameters
Vmax:
the voltage value from the highest point of the waveform to the GND.
Vmin:
the voltage value from the lowest point of the waveform to the GND.
Vpp:
the voltage value from the highest point to the lowest point of the waveform.
Vtop:
the voltage value from the flat top of the waveform to the GND.
Vbase:
the voltage value from the flat base of the waveform to the GND.
Vamp:
the voltage value from the top of the waveform to the base of the waveform.
Vavg:
the arithmetic average value on the whole waveform or on the gating area.
