DSO switches to YT mode and AUTO status.
4. At the mode of Autoscale, DSO is always in the state of DC coupling and AUTO
triggering. In this case, making Triggering or Coupling settings have no effect.
5. At the mode of Autoscale, if adjust the vertical position, voltage division, trigger
level or time scale of CH1 or CH2, the oscilloscope will turn off Autoscale
function and if press Autoset again, the oscilloscope will enter into Autoscale.
6. Turn off the submenu at the Autoscale menu, the Autoscale is off and turn on the
submenu still enters into the function.
7. When video triggering, the horizontal time scale is 50us. If one channel is
showing edge signal, the other channel is showing video one, the time scale refers
to 50us as video one as standard.
8. While the Autoscale is working, below settings will be made forcibly:
(1) The unit will switch from non-main time base to main time base status.
(2) The unit will switch to Peak detection menu while in the state of Average
sampling mode.
How to Use Executive Buttons
Executive Buttons include Autoset, Run/Stop, Single, Copy.
Autoset
This button is used for the automatic setting of all control values of the
instrument to generate the waveform suitable for observation. Press the Autoset
button and the oscilloscope will perform the fast automatic measurement of the
signal.
The function items of Autoset are shown as the following table:
