Dear

When debug the ultrasonic gas flow rate with the EVM430-FR6043 development board, there is a problem with the ADC acquisition and capture of graphics using a 200KHz ultrasonic transducer during communication with the USS upper computer (as shown in the figure below). What is the reason for this problem and how can it be improved? (The configuration diagram is shown below)

Hi Billy,

Have you tried probing the device's channel pins with an oscilloscope to see if this is an issue with the ADC, or an issue where the signal is actually experiencing some very large excitation before the pulse generation, as shown? I would not expect the highlighted waveform to appear due to any signals shown in the USS GUI.
