I

t
The I²t analysis integrates the square of the current over time when a device under test is turned
on. This relates to the rate at which a circuit heats, which is critical for applications such as sizing
a circuit's fuse.
Interpreting an I
2
t analysis
An example of an I
2
t analysis is shown below:
The bright horizontal yellow line is the current signal (I). It is yellow in this case because the
Current Source is Channel 1. The bumpy, bright magenta line is a math function, the square of
the current (I
2
). The rising purple line is the integral of the I
2
signal over time (I
2
t). The orange
vertical and horizontal lines are the cursors delimiting the calculations shown in the sidebar.
