OK, thank you.

Analize GPIB communication. I found instrument manual, here is link(file is too large for upload):

http://f6fzk.free.fr/DOCUMENTATION/DOC%20HP/CD6/54645a_d_prg.pdf

 Can you please look it and tell me on which page are GPIB command???

I need to write and explain command which do next:

1. initialize using dig. scope and function generator

2. reading waveform

3. setting up output parameters of function generator.

Also, i need to show and describe block which is used for receiving GPIB command which we send by bus. Which blok is that?

Were can i found code of virtual instrument which is in charge for communication with instruments? I have to write and describe part of that code.

Many questions, i am sorry, but i am completely nub for this... i hope i will learn it here, so next time i can help someone.

Thanks you.

Sounds like you need to view the LabVIEW tutorials. http://www.ni.com/academic/students/learnlabview/ which you seems to have totally ignored.

That whole document defines the GPIB commands. The specific commands are in section 8.

You've already got the virtual instruments for the scope and function generator. Those are the instrument drivers that you used. At a very low level, communication occurs with VISA functions which actually abstract the even lower level GPIB commands such as ibwrt, ibrd, etc.

Again me... in attachment is my whole project. And i still cant do one think. On front panel of my virtual instrument i have to show GPIB commands, i still don't know how to do that,  i know that i can see GPIB command using NI Spy, but my assignment is to make it visible on front panel of my virtual instrument. Please help.
