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
WISMO218. The goal is to separate the WISMO218 Development Kit board consumption from the
WISMO218 consumption - which is measured by the oth er 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 WISMO218 Development Kit dur ing all consumption measurements.
