11 Quickly Capture the Signal
This is an example describing how to acquire a signal quickly. In this example, we
assume the signal is connected to channel 1 and other channels are disabled.
First, press the channel 1 button to turn on channel 1. The LED on the
button lights and the descriptor box of channel 1 is displayed at the
bottom of the screen.
Second, press the Auto Setup button. The oscilloscope will automatically
adjust the vertical scale, horizontal scale, and trigger level according to the
input signal to get the optimum waveform display.
Auto Setup will not work on all signal types, especially time-varying bursts or slow
signals (< 100 Hz). If Auto Setup cannot achieve desired settings, you can manually
adjust the vertical, horizontal, and trigger systems. See the chapters "Vertical Setup",
"Horizontal and Acquisition Setup" and "Trigger" for details.
