oscilloscope detects a trigger it completes the acquisition and

stops.

When you push the RUN/STOP or SINGLE buttons to start an

acquisition, the oscilloscope goes through the following steps:

1. Acquire enough data to fill the portion of the waveform

record to the left of the trigger point. This is also called the

pre-trigger.

2. Continue to acquire data while waiting for the trigger

condition to occur.

3. Detect the trigger condition.

4. Continue to acquire data until the waveform record is full.

5. Display the newly acquired waveform.

• Time Base: The oscilloscope digitizes waveforms by acquiring

the value of an input signal at discrete points. The time base

allows you to control how often the values are digitized. To adjust

the time base to a horizontal scale that suits your purpose, use the

time/div knob.

• Time Domain Aliasing: Aliasing occurs when the oscilloscope

does not sample the signal fast enough to construct an accurate

waveform record. When this happens, the oscilloscope displays a
