Impact on EVM
In this section, we will study the impact of using the CFR engines within the transceiver on EVM performance. The same LTE 20
MHz tone (PAR=12.67 dB) as used in the section above is used here as an example. The set up information for this waveform is
described below.
Setup:
Carrier 1 Center Frequency = 0 MHz
Output Sample Rate = 245.76 MHz
DAC Resolution = 16
Output Data Format = 2s Complement
Scaling = 0 dB
Modulation = 64QAM
Test model = 3.1
Final PAR (dB) = 12.2
The EVM observed before applying CFR is shown in Figure 60.
