MEASURE

We'll see in this section the different options available to the user within the 'MEASURE' sub-menu.

The 'Measure' menu is a bit different from the other ones because it is divided in 2 parts :

  • Math functions, these can generate new signals from pre-existing ones.
  • Auto measures, these are used to display 'quick-read' informations at the bottom of the screen such as vpp, min value, max value, etc.

You can switch between one of these two sections using the blue button at the bottom of the sub-menu.

Math functions

The math-functions sub-menu will allow you to generate signals from pre-existing ones.

Here is the description of each input within this sub-menu and what they'll do :

  • Channel slot : Which unoccupied channel slot should the new signal use ?
  • Channel : What channel are we using as a base for the operation ?
  • Operation : What type of operation are we using on the signal ?
  • Channel 2 (If operation selected needs two operands) : What is the 2nd base channel ?

There are a total of 8 operation types, some of them require a second base channel to create the new signal :

  • Addition (Needs a 2nd signal)
  • Substraction (Needs a 2nd signal)
  • Multiplication (Needs a 2nd signal)
  • Division (Needs a 2nd signal)
  • Squared
  • Derivative
  • Integral
  • Fast Fourrier Transform

Once you've selected the parameters, simply hit 'SAVE' to generate the new signal as you specified.

Creating a new signal using the 'math functions' sub-menu.
Newly created signal.

As you can see in the figure above on the left, once a signal is created, it will be displayed within this sub-menu with an icon to delete it if needed.

In the example above, since we've specified CH6 as slot for the newly generated signal, this spot will no longer be available to generate new signals on.
It is however possible to use the CH6 signal as a base to generate another one since it will be now considered the same as any other base signal.

Auto-measures

The auto-measures sub-menu will allow a user to select from a multitude of values which ones to display below the oscilloscope's screen.

The sub-menu for auto-measures works like so :

  • Channel : On top of the menu is where you select what channel these measurements should be based on.
  • Below this are each auto-measurements available, simply click on one and the corresponding measure will now be displayed below the screen.
    To get rid of a set measurement, simply click on it again (gray options aren't displayed and green ones are).
  • The reset button will remove all auto-measures.

The measurements appearing below the screen will be the color of the selected channel in the auto-measures sub-menu.
