4. Consumption Measurement
Procedure
This chapter describes the consumption measurement procedure used to obtain the WISMO218
consumption specification.
The WISMO218 consumption specification values are measured for all operating modes available on
the product.
Consumption results are highly dependent on the hardware configuration used during measurement.
This chapter also describes the hardware configuration settings that must be used to obtain optimum
consumption measurements.
Hardware Configuration
The following hardware configuration includes both the measurement equipment and the WISMO218
with its socket-up board on the WISMO218 development kit.
Equipment
Four devices are used to perform consumption measurement:

A communication tester

A current measuring power supply

A standalone power supply

A computer, to control the WISMO218 and save measurement data
