Peak-Peak
The peak-to-peak value is the difference between Maximum and Minimum values.
The Y markers show the values being measured.
Maximum
Maximum is the highest value in the waveform display. The Y marker shows the
value being measured.
Minimum
Minimum is the lowest value in the waveform display. The Y marker shows the
value being measured.
Y at X
Y at X measures the vertical value at a specified horizontal location on the specified
source waveform. The horizontal location must be on the screen.
When the horizontal axis is time, the horizontal location is a time value referenced
to the trigger event.
When the source is an FFT (Fast Fourier Transform) waveform, the horizontal axis
is frequency instead of time, and the horizontal location is a frequency value.
Amplitude
The Amplitude of a waveform is the difference between its Top and Base values.
The Y markers show the values being measured.
Top
The Top of a waveform is the mode (most common value) of the upper part of the
waveform, or if the mode is not well defined, the top is the same as Maximum. The
Y marker shows the value being measured.
