Note:
The FFT math waveform vertical scale is dBVRMS, which is dB relative to 1 VRMS (0 dB = 1 VRMS).

7. Application examples

7.1. Understanding Major-Functions
7.1.1. Using "Utility" for Calibration
Before you start making any measurements, it might be useful to use UTILITY function and to choose Self-calibration
to prepare the oscilloscope. This process may take a few minutes.
7.1.2. Using "AUTOSET"
Suppose you set up the oscilloscope, put the probe to some target, and want to see the signal rapidly with no detailed
information of the signal like the frequency and amplitude. You can do this with AUTOSET function. Using this is
simple:
1. Set the probe attenuation to 10X and connect to the circuit.
2. Press AUTOSET next to the POWER button. The oscilloscope will automatically display the waveform with certain
amplitude and frequency.
Consider the simple setup below:
7.1.3. Using "HORIZONTAL" and "VERTICAL" knobs to adjust display
Suppose once you see the signal, you want to adjust the display and several ways including zooming into the signal.
To do this,
1. Change the POSITION knob in VERTICAL to adjust the signal's vertical level.
2. Turn VOLTS/DIV to zoom vertically.
3. Turn TIME/DIV to zoom horizontally.
4. Change the POSITION knob in HORIZONTAL to adjust the horizontal position.
7.1.4. Using "DISPLAY" to adjust viewing
Once you see the signal, you may want to modify the display to suit your needs. You will see five submenus that can
be used to adjust the display.
1. Press on the blue button next to Type to switch displaying the waveform display between Vectors and Dots.
2. Format (YT/XY) is irrelevant for now, but XY is used when there are two channel inputs.
3. Grid options can be used for switching between different grid styles.
