Power Consumption
The communication tester is a CMW 500 or CMU 200 (GSM and WCDMA only) from Rhode &
Schwartz. This tester offers all required GSM, WCDMA and LTE network configurations and allows a
wide range of network configurations to be set.
The 66321D power supply is used to supply the modem, and it could also be used to measure the
total current drain by the device. The “current measuring power supply” is also connected and
controlled by the computer (GPIB control not shown in the previous figure).
Note that a SIM must be inserted during all consumption measurements.
The following table lists the recommended equipment to use for the consumption measurement.
