about VISA read

If I wrote different values to different registers by using VISA write. Then I connected a VISA read after the last VISA write. How can I know the read buffer returned is from which register?

What you read is totally dependent on the instrument itself. You have not provided the make and model of the instrument so how can you expect anyone to provide an answer? Have you studied the programming manual?

Hi,

this is the capture:

the instrument is Emcore TTX 1994, and the application note is attached. I only want to read the value from a certain register, but there are many VISA writes concatenated before VISA read, so I don't know which value is returned from VISA read.
