The following hardware configuration includes both the measurement equipment and the Fastrack
Xtend.
12.8.1.1. Equipment
Three devices are used to perform consumption measurement:
 A communication tester
 A current measuring power supply
 A computer, to control the Fastrack Xtend and to save measurement data
Figure 45. Typical Hardware Configuration for Power Consumption Measurement
The communication tester is a CMU 200 from Rhode & Schwartz. This tester offers all required
GSM/GPRS/EGPRS/CDMA/WCDMA network configurations and allows a wide range of network
configurations to be set.
The 66321D power supply is used to supply the Fastrack Xtend, and it could also be used to measure
the total current drain by the device. The current measurement data is read through the GPIB
connection. Rhode & Schwartz NGSM 32/10 is used when measuring with 32V input voltage.
Note that a SIM card must be inserted during all consumption measurements.
The following table lists the recommended equipments to use for the consumption measurement.
