How to acquire signal data from the Agilent E4438C Function Generator to the LV8.0?

[M.V.]

Hi!

I'm new to the Labview and I've got few questions. 

I would like to acquire data from the function generator. My FuncGen is Agilent E4438C and it is connected to my laptop via GPIB - USB.

-What do I need to get this data out and how can I see the signal in the LV front panel?

-How can I control the frequency of FuncGen with my LabView? Is it even possible?

Can someone attach a screenshot of block diagram where I can see all blocks that I need? All other help will also do just fine, so I get things rolling.

I haven't found any help and I've been looking for whole day now from the help files, internet and other places.

Thanks a lot in advance.

There is a driver available from the Instrument Driver Network. There is a utility in LabVIEW that will search this site for you and get the driver. If you do to this site, check the resources on what a driver is and how to use it.

I've downloaded the files that are listed in the http://sine.ni.com/apps/we/niid_web_display.download_page?p_id_guid=047541633C5C5B05E0440003BA7CCD71.

I still do not know what the first block in the block diagram should be. My meaning is that should the first block be DAQ assistant, Instr assist, Instr drivers from the Input menu or differently something else.

If someone could give me a hint what example first two blocks should be, I might get my system built on my own.

I've also configured MAX so that I can communicate with my instrument.

The driver comes with a couple of examples. They are hpesgdxx Config FM Signal Example and hpesgdxx Config NADC Signal Example. either one should give you an idea on how to get started and which functions to use. These high level examples are not really intended to be called by another VI. Rather, they show what lower level functions to include. For example, you would always start with the intialize function. Place other functions such as configure frequency and ampliture where you need them. Be sure to turn on context help in order to see the documentation for each function in the driver.

DAQ Assistant has nothing to do with GPIB instruments. It is used for internal DAQ cards from NI. The Instrument I/O Assistant would be used in place of driver functions or when no driver is available.

Thank you Dennis for your advices. You have been more than helpful. I'll try those examples and I will return when I have my function generator under the control.
