The sampling is performed on a waveform when one trigger is
detected, then stop sampling. .

Coupling AC

suppression

LF
suppression

With this mode selected, the DC component is prevented
from passing-though.
All dc components are allowed.

The HF part of the signal is prohibited and only the HF
component is allowed.

The LF part of the signal is prohibited and only the LF
component is allowed.

7.5.2 Video Triggering

With

Video triggering

selected, the oscilloscope performs the

NTSC, PAL

or

SECAM

standard

video signals field or line trigger.

Now, you can see a screen that looks like the following figure 39, figure 40.
