Part Number: MSP430FR5043

Hi team,

Herr's an issue from the customer may need your help:

As the following figure, what might be the possible reason for the following bad waveform? 

Could you help check this case? Thanks.

Best Regards,

    Hi Cherry,

    It's difficult to tell without some background information.

    1. I assume this is a GAS application, so what is the transducer/pipe manufacturer and frequency the customer is using?

    2. Is this a new project and customer is seeing this issue for the first time, or is this waveform measure on one "bad" unit and other units are working ok?

    3. Was this waveform captured from TI EVM or customer PCB?

    4. Can the customer take another screen shot including the left axis (adc counts)?
