Oscilloscope Functions
To Set Channel
Press , , or to activate the on-screen display of the waveform acquired by the specified channel, or to change the selected acquisition channel. When the button is fully colored it means that the on-screen display of the waveform acquired by that channel is activated and the channel is selected to change its parameters, when the button only has a colored stripe below , it means that the on-screen display of The waveform acquired by that channel is activated but it is not selected to be able to change its parameters, when the button is completely gray , it means that the display of the data acquired by that channel is off and it is also not selected for parameter editing.

Detailed Instructions
Horizontal cursor 1: To activate / deactivate the horizontal cursor 1 press the button in the horizontal cursors menu, when the button turns green, it means that the cursor is activated. When it turns blue it means it is disabled. When cursor 1 is activated, it is displayed in red on the screen. After being activated, its position can be changed using the knob or arrows.
-
Horizontal cursor 2: To activate / deactivate the horizontal cursor 2 press the button in the horizontal cursors menu, when the button turns green, it means that the cursor is activated. When it turns blue it means it is disabled. When cursor 2 is activated, it is displayed in green on the screen. After being activated, its position can be changed using the knob or arrows.
Horizontal cursor 3: To activate / deactivate the horizontal cursor 3 press the button in the horizontal cursors menu, when the button turns green, it means that the cursor is activated. When it turns blue it means it is disabled. When cursor 3 is activated, it is displayed in magenta on the screen. After being activated, its position can be changed using the knob or arrows.
Horizontal cursor 4: To activate / deactivate the horizontal cursor 4 press the button in the horizontal cursors menu, when the button turns green, it means that the cursor is activated. When it turns blue it means it is disabled. When cursor 4 is activated, it is displayed in blue on the screen. After being activated, its position can be changed using the knob or arrows.
Horizontal cursor delta: The horizontal delta cursor shows the time difference between its own position and the position of the selected cursor. To activate / deactivate the horizontal cursor delta press the button in the horizontal cursors menu, when the button turns green, it means that the cursor is activated. When it turns blue it means it is disabled. When cursor delta is activated, it changes the color depending on the cursor that you have as reference measure. For example, in the following figure, the delta cursor has the horizontal cursor 3 as measurement reference, therefore, its color will be the same than the cursor 3 (magenta). If the reference cursor changes to horizontal cursor 1, the color of the delta cursor would change to red, which is the color of cursor 1. After the horizontal delta cursor is activated, its position can be changed using the knob or the arrows.
Multiple horizontal cursors: Multiple horizontal cursors can be shown on the screen at the same time, in this case the menu button corresponding to the selected cursor will appear in green and the others that are activated on the screen, but not selected will appear in yellow. In the following figure the five cursors are activated on the screen, but the selected cursor is the delta cursor, because its button appears in green and the rest in yellow, like delta cursor is the selected one, it can be moved in position using knob and arrows.

Save a .csv File
The .csv file option allows you to generate and save a file with a .csv extension where each of the time samples and their corresponding amplitude value are stored for each of the channels that are turned on at the time of generating the file. It also saves the value of the time base and the trigger position. This file can be opened and graphed in programs like Microsoft Excel and Matlab.
