Values measured for each waveform, updated every second, according to the
measurement type chosen with the variable function buttons. Value will be
color matched to its waveform.
Instantaneous values of signals at time “t”, at the intersection of the cursor
and the waveforms. The cursor is moved along the time axis with the
buttons.
