Reference
Sine wave Details
Single-cycle sine
Sets the horizontal scale to display about one cycle
of the waveform; the oscilloscope displays Mean, and
Peak-to-Peak automatic measurements
FFT
Converts the input time-domain signal into its frequency
components and displays the result as a graph of
frequency versus magnitude (spectrum); because this is a
mathematical calculation, refer to the
Math FFT chapter
for more information
(See page 61,
Math FFT .)

Square Wave or Pulse When you use the Autoset function and the oscilloscope determines that the signal
is similar to a square wave or pulse, the oscilloscope displays the following
options:
Square wave or Details
Multi-cycle square
Displays several cycles with appropriate vertical and
horizontal scaling; the oscilloscope displays Pk-Pk, Mean,
Period, and Frequency automatic measurements
Single-cycle square
Sets the horizontal scale to display about one cycle of the
waveform; the oscilloscope displays Min, Max, Mean, and
Positive Width automatic measurements
Rising edge
Displays the edge, and the Rise Time and Peak-to-Peak
automatic measurements
Falling edge
Displays the edge, and the Fall Time and Peak-to-Peak
automatic measurements
Undo Autoset Causes the oscilloscope to recall the previous setup
Video Signal When you use the Autoset function and the oscilloscope determines that the signal
is a video signal, the oscilloscope displays the following options:
