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

To measure the peak of an FFT
1 Select FFT as the Operator in the Waveform Math Menu.
2 Choose Math: f(t) as the source in the Measurement Menu.
3 Choose Maximum and X at Max Y measurements.
Maximum units are in dB and X at Max Y units are in Hertz for FFT.
