How to measure the Data setup time

[Daniel_Tan]

I want to do a SPI timing AC characteristics.

I use labview capture a frame of SPI data package from a oscilloscope and display in a waveform Graph.

Lead time, Data setup time, data hold time... should be measured.

So, what is the next  step should i do?

Thanks

We will need a lot more information. What device are you getting data from? How are you communicating? Have you looked in the examples for something close to what you are trying to do. There is a lot of great stuff out there already that should get you a good start on your project. We would like to see you put in some effort before we try to help.

Thank you, asastet.

I test the SPI module of a MCU. I have download a code to init the SPI and transfer a data package continuously.

The 4 channels of oscilloscope connected with SS, CLK, MOSI, MISO.

In labview, I capture a frame of SPI data package from oscilloscope and display in waveform graph control.

My project will automatically measure the data setup time and data hold time according CLK vs. MOSI.

Thanks.
