6. Power Consumption
6.1. Consumption Measurement Procedure
This chapter describes the procedure for consumption measurement which is used to obtain the
modem’s consumption specifications.
The modem consumption specification values are measured for all operating modes available on this
product. For more information about the different operating modes, refer to section 6.2 Operating
Modes.
Consumption results are highly dependent on the hardware configuration used during measurement
and the following chapter describes the hardware configuration settings that should be used to obtain
optimum consumption measurements.
6.1.1. Hardware Configuration
The following hardware configuration includes both the measurement equipment and the modem.
6.1.1.1. Equipment
Three devices are used to perform consumption measurement:

A communication tester

A current measuring power supply

A computer, to control the modem and to save measurement data
Figure 10. Typical Hardware Configuration
The communication tester is a CMU 200 from Rhode & Schwartz. This tester offers all required
GSM/GPRS and WCDMA network configurations and allows a wide range of network configurations
to be set.
