flickering on the top left of the screen.
2. In the mode of Autoscale, the oscilloscope can self-estimate Trigger Mode
(Edge, Video). At this point, the trigger menu is not available.
3. When the input signal contains the DC component, the coupling will be set
to AC, the amplitude of the input signal should be greater than 5mV, and
the frequency should be greater than 20Hz.
4. At the mode of Autoscale, DSO is always set as DC coupling with AUTO
triggering, the holdoff is set to 100ns.
5. At the mode of Autoscale, if adjust the vertical position, voltage division,
trigger level or time scale, the oscilloscope will pause the Autoscale
function. To resume Autoscale, push the Autoset front panel button.
6. When video triggering, the horizontal time scale is 50us.
7. While the Autoscale is working, the settings below will be made forcibly:
The DSO will switch from the wave zoom mode to the normal mode.
In the decoding, pass/fail or XY mode, when entering into Autoscale, these
modes will be turned off.
