Oscilloscope Functions The Sin(x)/x Interpolation: Note: The default interpolation mode is Sin(x)/x. Acquisition When you acquire a signal, the oscilloscope converts it into a digital form and displays a waveform. The acquisition mode defines how the signal is digitized and the time base setting affects the time span and level of detail in the acquisition.
Oscilloscope Functions 3.11 Acquisition Modes There are three acquisition modes: Normal, Average and Peak Detect. Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spaced intervals to construct the waveform. Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages them, and displays the resulting waveform.

Application Example 4.1 Simple Measurement To acquire and display a signal, please do the steps as follows: 1. Connect signal to CH1 by using probe 2. Click the button on toolbar or “Acquire -> Auto Setup” on menu. The DSO set the vertical, horizontal, and triggers controls at the best status automatically. Also, you can adjust the controls to meet your measurement to optimize the waveform display.
Application Example 4.2 Capturing a Single-Shot Signal To capture a single event, it needs to gather some pre-test knowledge of the signal in order to set up the trigger level and slope correctly. For example, if the event is derived from 3.3V COMS logic, a trigger level of 1.2 or higher Volts should work on a rising edge.
