Hi,
How this analyzer measure voltage and current? Is there any shunt-resistor on bus VBUS?
Is there any schematic file?
Thanks

Hi,
We have a series resistor on the VBUS pin and the voltage drop is measured by using a current sense amplifier. The VBUS is measured using a resistive divider on a VBUS monitoring GPIO.
Unfortunately, we wont be able to share the schematic file.
Best Regards,
Sananya
