Figure 4.17 Autoscale function
1. When entering into Autoscale function, a autoscale indicator will be 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. In the STOP status,
when entering into Autoscale, the status will be set to RUN.
