An example of the CW Doppler output, as shown in Figure 19
and Figure 20, can be seen in the frequency and time domain,
respectively. Make sure to set the analog input level appro-
priately to achieve full scale throughout the signal chain.

tab of the SPI Controller, where
X
is the
channel to which an analog input is applied, find the
CW_IQ_DEMOD_PH(2D)
box. Select the
