Fig. 9.4 Setup for OFDM measurements

9.3 Setup Used for the OFDM Measurements

Figure 9.4 depicts the measurement setup used for the OFDM characterization. This
setup was used for the measurements presented in Sect. 4.5.2. These measurements
were performed in the Fujitsu Laboratories facilities in Kawasaki, Japan.
The OFDM signal is provided by the signal generator E4438C which is split and
fed to the MAIN and ENV evaluation boards. The amplified signal is characterized
with the signal analyzer R3681 which provides the output power as well as the EVM
readings. The oscilloscope Infiniium is used to monitor the dynamic supply signal.
The total current consumed by the RF power amplifier and modulator is read from
the DC source that also functions as a current monitor. The list of material used in
this setup is given in Table 9.3 .
