X at Max Y
X at Max Y is the X axis value (usually time) at the first displayed
occurrence of the waveform Maximum, starting from the left-side of the
display. For periodic signals, the position of the maximum may vary
throughout the waveform. The X cursor shows where the current X at Max
Y value is being measured.
