I am trying to get measurements of microprocessor power. My current plan is to identify the 12V power line feeding the microprocessor and log its current voltage using a clamp-on ammeter and general-purpose digital multimeter. I would like tools capable of measurements down to 100mA and sampling frequencies in the 10KHz range.
Would you have any suggestions on either the approach or the sort of tools I should use? I'd appreciate any recommendations.
