3.7. User interface introduction
1. Waveform Viewing Area.
2. The Trigger State indicates the following information:
Auto:
The oscilloscope is under the Automatic mode and is collecting the waveform under the
non-trigger state.
Trig: The oscilloscope has already detected a trigger signal and is collecting the after-triggering
information.
Ready: All pre-triggered data have been captured and the oscilloscope has been already ready for
accepting a trigger.
Scan: The oscilloscope captures and displays the waveform data continuously in the scan mode.
Stop: The oscilloscope has already stopped the waveform data acquisition.
3. The purple pointer indicates the horizontal trigger position, which can be adjusted by the horizontal
position control knob.
4. The pointer indicates the trigger position in the internal memory.
5. The two yellow dotted lines indicate the size of the viewing expanded window.
6. It shows present triggering value and displays the site of present window in internal memory.
7. It shows setting time (see "27.2.1 "Config" on page 137)
8. It indicates that there is a U disk connecting with the oscilloscope.
9. Indicating battery power status (see "27.2.2. "Display" on page 138).
10. The red pointer shows the trigger level position for CH1.
11. The waveform of CH1.
12. The positions of two purple dotted line cursors measurements.
13. The yellow pointer shows the trigger level position for CH2.
14. The waveform of CH2.
15. The frequency of the trigger signal of CH1.
