about VisualAnalog

Dear Sir/Madam,

We are going to use AD9257 for Image sensor and studying VisualAnalog

using AD9257-65EBZ and HSC-ADC-EVALCZ.

AD9257 is connected with 8-ch CMOS sensor.

So,we want to acquire Row_data of AD9257.

What is the simple or best method using VisualAnlog?.

Attached image is sample canvas.

It would be greatly appreciated if advice could be gotten.

Sincerely yours,

Kou

  • Hello Kou-san,

    As another sanity check, please make sure that the output format in VisualAnalog matches the AD9257 format setting in SPIController.

    At smaller signal amplitude where the MSB is not toggled, we might get misleading readings.

    Also, you can use the VisualAnalog "Logic" canvas to see which bits are actually toggling (just like a logic analyzer) to get better insight into what is happening. Please let me know if you need more information about this.

    Thank you.
