FUNCTIONAL TEST SETUP

1. Open a PuTTY session to the Zedboard's COM port.

2. In the PuTTY terminal, navigate to the /boot folder and run the

setup_adc.sh script.

3. Launch IIO Oscilloscope and connect to the Zedboard, as

shown in Figure 15.

4. In IIO Oscilloscope, set the AD3552R DAC output ranges to

±10 V and the input source to dma_input, as shown in Figure

16.

TEST RESULTS

After following the circuit evaluation procedure, the waveforms

loaded from the DAC Data Manager tab must appear in the IIO Os-

cilloscope waveform window, which displays the signals captured

at each ADC channel input. Figure 19 shows an example display

using the sample waveforms selected, as shown in Figure 18.
