2.1 Hardware

The SAM R30 is used as a Mi-Wi sleeping device for all the measurements. Connect the current probe over a cable that is connected between the pins of the current measurement header of the SAM R30 (see the following figure).

Do the data comparison between the power values of the SAM R30 XPro and SAM R30 Module XPro under specific scenarios.

The measurement setup for the Active mode (all operating modes like Transmit (TX)/Receive (RX) except Sleep) current consumption consists of the below items:
  • Tektronix TCP 202A current probe
  • Tektronix DPO 7254 oscilloscope

With the above measurement setup, the offset error varies between 200-1000 µA, and this was offset in each measurement. The user can measure the error by taking a mean measurement of the duration when the device is in the Sleep mode. The Digital Multimeter (DMM) measures the sleep current consumption.
