4 Consumption Measurement Procedure

This chapter describes the procedure for consumption measurement which is used to

obtain the Wireless CPU

consumption specification.

Q64/OASS1.0 consumption specification values are measured for all operating modes

available on this product. See the appendix of document

[4] AT Command Interface

Guide for Open AT

Firmware v6.5.

Consumption results are highly dependent on the hardware configuration used during

measurement, this chapter describes the hardware configuration settings that should

be used to obtain optimum consumption measurements.

4.1 Hardware Configuration

The hardware configuration includes the measurement equipment and the Wireless

CPU

with its motherboard.

4.1.1 Equipment

Four devices are used to perform consumption measurement:

¾ A communication tester

¾ A current measuring power supply

¾ A standalone power supply

¾ A computer, to control the Wireless CPU

and save measurement data.
