The Autoset function examines all channels for signals and displays corresponding
waveforms. Autoset also determines the trigger source based on the following
conditions:
If multiple channels have signals, the oscilloscope displays the channel with
the lowest frequency signal.
If no signals are found, then the oscilloscope displays the lowest-numbered
channel when Autoset was invoked.
If no signals are found and no channels are displayed, then the oscilloscope
displays and uses channel 1.
When you use Autoset and the oscilloscope cannot determine the signal type, the
oscilloscope adjusts the horizontal and the vertical scales, then takes the Mean
and Pk-to-Pk automatic measurements.
The Autoset function is usually more useful than Autorange in the following
situations:
Troubleshooting one stable signal
Automatically seeing measurements of your signal
Easily changing how the signal is presented. For example, viewing only one
cycle of the waveform, or the rising edge of the waveform
Viewing video signals or FFT signals
Sine Wave When you use the Autoset function and the oscilloscope determines that the signal
is similar to a sine wave, the oscilloscope displays the following options:
Sine wave Details
Multi-cycle sine
Displays several cycles with appropriate vertical and
horizontal scaling; the oscilloscope displays Cycle
RMS, Frequency, Period, and Peak-to-Peak automatic
measurements
