8.1 Parameter Measurement
UPO1000CS series oscilloscope can automatically measure 36 kinds of parameters. It includes voltage,
time and other.
① Voltage
Max：The voltage from the highest point of the waveform to GND.
Min：The voltage from the lowest point of the waveform to GND.
High：The voltage value from the flat top to GND.
Low: The voltage value from the bottom to GND.
Middle: Half of the sum of the voltage values at the top and bottom of the waveform
Pk-Pk: Peak-to-peak value, the voltage value from the highest point to the lowest point of the waveform.
Amp：Voltage from top to bottom of the waveform.
Mean：The average amplitude of the waveform in the screen.
CycMean：Average amplitude of the waveform in one period.
RMS: The effective value. The energy generated by the conversion of AC signal, it corresponds to the
DC voltage that generates equivalent energy.
CycRMS: The energy produced by the conversion of AC signal in a period, it corresponds to a DC
voltage that generates equivalent energy.
AC RMS: The RMS value is the waveform which DC component has removed.
② Time
Period: Time between two consecutive, same-polarity edges of a repetitive waveform.
Frequency: The reciprocal of the period.
Rise time: Time needed for waveform amplitude rising from 10% to 90%.
Fall time: Time needed for waveform amplitude falling from 90% to 10%.
