Oscilloscope Advanced Usage (Math Functions)

You can display mathematical operations on your plotted waveforms (e.g. subtract two waveforms)

Press the Math button

You should now see a set of on-screen options which modify different parameters such as what type of function is being performed, on which signals, and in what order.

Press a softkey (one of the buttons under the on-screen options) under the parameter you wish to change to pull up a pop-up menu for selection of options.

Press again to toggle/scroll theough the options. Once the scrolling menu is on the option you want to select, simply stop scrolling, and the pop-up menu will disappear.

Alternatively, you can use the select wheel in the “Trigger” section of buttons to scroll through the lists in the pop-up menus.

The first button toggles between displayed and internal

The second scrolls through different operators to be used in the following way:

Source 1 (operator) Source 2

The last two toggle which signals/probes should be used for Sources 1 and 2

Math functions, can be rescaled vertically and repositioned vertically, just like the signals captured by the probes

The top knob is for vertical scale adjustment

The bottom knob is for vertical offset adjustment

Reposition the math function as well as your signals in such a way that it is easy for you to read.
