This page explains how to get the best display of your application's data in System Analyzer.
Elements of the display
The following elements are present in the System Analyzer window:
Sometimes, measurement values cannot be displayed correctly. This is indicated using different line colors.
You can zoom in or out of signals using the mouse wheel or the zoom buttons:
Change the signal scale manually
To manually change the signal scale in System Analyzer, follow these steps:
Running through the power measurement results, use the following hints to create a convenient signal display:
Working with power consumption data
Selectable from the context menu, the power data can be filtered. Select 160 kHz filtering to have a great view on all spikes and their height or “special” noise, such as overshoots:
Select 5 kHz to have a great view of what’s hidden in the noise, for example current drain of the target's internal pull-up resistors:
You can calibrate the power measurement offset introduced by ULINKplus by using the Zero Point Adjustment in the context menu:
This will compensate for the offset and show 0 mA at the current position. You can also remove this adjustment at a later point in time, if required.
Power consumption data is only available when using a ULINKplus debug adapter.
