Equivalent Time Sampling
The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution (equivalent to
50GSa/s). This mode is good for observing repetitive waveforms.
■ Real Time Sampling
The scope has the highest Real-time sampling rate up to 1GSa/s.

“RUN/STOP” Button
Press the RUN/STOP button when you want the oscilloscope to acquire waveforms continuously. Press the
button again to stop the acquisition.
■ “SINGLE” Button
Press the SINGLE button to acquire a single waveform. Each time you push the SINGLE button, the
oscilloscope begins to acquire another waveform. After the 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. Use S/div knob to adjust the time base to a
horizontal scale suits your purpose .
