Trying to measure the inrush on a full speed USB device. The current probe seems to be working outside of the USB test framework: plugging/unplugging my device creates a level change with a number of transient spikes. However, when I actually try to run the automated test, it keeps coming back with a value of 0 microC. I'm good, but not THAT good. Tried trigger levels from 50mA-250mA with no luck, stretched the timebase way out. Current probe was zero'd out each time before running the test. Any thoughts?
