In YT mode, the relative relationship between vertical voltage and horizontal time is displayed. Y axis represents
the voltage, X axis represents the time, and the waveform is displayed after triggering (waveform displayed from
left to right).
Note: When the time base is large (such as 200ms and above), sometimes the waveform will not be displayed for a
long time; this is because in YT mode, the waveform must be triggered before display. It is closely related to the
time base and can be roughly calculated as: the number of divisions on the left side of the trigger position * time
base level position; if you want to reduce the waiting time, move the trigger position to the left.
The case that trigger position is moved out of the waveform screen is not considered here.
ROLL—— ROLL Mode
In ROLL mode, the waveform rolls from right to left to refresh the display (see Figure 3-6 ROLL Mode). The
horizontal time base adjustment range of the ROLL mode in the running state is 200ms/div~1ks/div.
In ROLL mode, trigger related information is invalid, including trigger position, trigger level, trigger voltage, etc.
