Hi @mysumithere and welcome to the forum!
The Joulescope min/max may be confusing for your desired capture (see explanation below). You can turn them off using the Waveform Control widget:
Another option is to set your Joulescope to a fixed 18 mA current range (the smallest range still larger than your maximum current). The waveform will then not have any autoranging artifacts.
So, why are min/max confusing? Joulescope is an autoranging shunt ammeter, which means that it inserts a variable resistance between your power supply and target load. The Joulescope shunt resistance, along with your cabling, forms a low-pass filter with your target’s capacitance. On an over-current event, your Joulescope decreases the shunt resistor value very quickly, which decreases the voltage across the shunt resistor. However, your target device’s capacitors must charge up, resulting in a current spike.
For the cleanest waveform, you can select a fixed current range. For the highest dynamic range, you want Joulescope’s autoranging feature. Check out this post for more discussion:
