Oscilloscope Functions
1.Source
The user can use the "Source" menu to select a measure source.
2. Vertical
Maximum: Voltage of the absolute maximum level, Measured over the entire waveform
Minimum: Voltage of the absolute minimum level, Measured over the entire waveform
Peak To Peak: Peak-to-peak = Max –Min, Measured over the entire waveform
Top: Voltage of the statistical maximum level, Measured over the entire waveform
Base: Voltage of the statistical minimum level, Measured over the entire waveform
Middle: Voltage of the 50% level from base to top
RMS: The Root Mean Square voltage over the entire waveform
Amplitude: Amp = Base - Top, Measured over the entire waveform
Mean: The arithmetic mean over the entire waveform
Cycle Mean: The arithmetic mean over the first cycle in the waveform
Preshoot: Positive Overshoot = (Max - Top)/Amp x 100 %, Measured over the entire
waveform
Overshoot: Negative Overshoot = (Base - Min)/Amp x 100 %, Measured over the entire waveform.
