Measurements
Since v0.13.0.0, the SmartScope includes a more advanced Measurement subsystem. Each measurement now shows more information (min/max/mean/std), and you can even watch how these values change over longer periods of time (even hours!) inside the SmartScope app itself.
Overview
The main GUI elements of the measurement subsystem are shown below, which will be used throughout the remainder of this page:
Measurement box
The measurement box contains the currently active measurements. The Value column displays the value calculated on each incoming wave. This value can vary very rapidly, and therefore the Mean column was added which shows the averaged value over 1 second. Added to this are the Min and Max columns, which show the minumum and maximal value of the measurement of said 1 second period. Finally, the Std column shows the standard deviation (~noise or variation) of this value over the 1 second interval.
The measurement box can be dragged around freely over the screen.
Removing the measurement box
By dragging the Measurement box out of the screen through the top or left side of the screen, it will be removed from the screen. Open the Measurement menu to show the measurement box again.
Docking the measurement box to the bottom of the screen
Typically the measurement box will be floating on top of your screen; and even though it is semi-transparant it can hide some parts you want to keep an eye on. Therefore, you can dock the measurement box to the bottom of the screen, which will make sure it no longer obscures other elements.
Docking the measurement box to the right side of the screen
Sometimes you're really only interested in the mean value of the measurement. For such cases, you can dock the measurement box to the right side of the screen, which will show the mean value in a much larger font. This can also be useful if you want to monitor a certain value from a distance.
Long-term measurement graphs
The Measurements menu is used to activate/deactivate measurements. The Measurements menu is integrated in the right part of the GUI. To open or hide the Measurements menu, hit the Ruler button at the bottom-right of the screen.
Once opened, the Measurement menu shows at its top the channel, followed by the measurements which can be invoked for this channel.
Add/remove to/from measurement box
Each measurement has an icon to the left, which is grayed out by default. Tap it to become active, which means the measurment is now active in the measurement box. Tap it again to disable the measurement; thereby removing it from the measurement box (and if present, removing its long-term graph). ==
