Product Technical Specification &
Customer Design Guidelines Consumption Measurement Procedure
Figure 42. Typical hardware configuration
The communication tester is a CMU 200 from Rhode & Schwartz. This tester offers all GSM/GPRS
network configurations required and allows a wide range of network configurations to be set.
The AX502 standalone power supply is used to supply all motherboard components except the
AirPrime WISMO218. The goal is to separate the AirPrime WS Series Development Kit board
consumption from the AirPrime WISMO218 consumption - which is measured by the other power
supply, the 66321B “current measuring power supply”.
The “current measuring power supply” is also connected and controlled by the computer (GPIB
control not shown in the previous figure).
A SIM must be inserted in the AirPrime WS Series Development Kit during all consumption
measurements.
