Compiler/TDC1000-TDC7200EVM: Can the oscilloscope shows multiple START, STOP, and COMP_IN signal ?

Part Number: TDC1000-TDC7200EVM
Other Parts Discussed in Thread: TDC7200

Tool/software: TI C/C++ Compiler

Hello,

The image shows the START, STOP, and COMP_IN signal. However, I would like to have multiple START, STOP and COMP_IN signal showed on the oscilloscope. Is it possible? 

Thank you,

Ajeera.

    Ajeera,

    I do not get your question properly, I see there is only 1 COMP_IN, START & STOP pins in TDC7200 EVM.

    In case you are wondering how to capture multiple STOPs then you should be capturing a longer time in the oscilloscope.

    Hope this answers your question.

    Hai,

    Thank you for the answer, I did the longer time on the oscilloscope. Here, is the image, I obtained. It showed multiple signals of COMP_IN, however, a very small, signal of the START, STOP signal, which almost cannot be read at all.

     

    From the GUI of the tDC1000-tdc7200evm, the excel file saved the TOF AVG data, which is the output signal. However, is it possible to gain input signal from the GUI itself? Can I actually read the transmit signal from the GUI? Is there anyways I can read the input signal from the GUI? What can the excel file save other than the TOF AVG data?

    Thank you.

    Ajeera,

    At the look of it looks like you have having an aliasing. Please reduce the timing window to see the START & STOP signals. You cannot see the START & STOP signal in the GUI.
