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%.
