graph scales & connection

If you can't get the correct signal on the scope manually, then I'm not sure why you are even posting to the LabVIEW forum. It sounds like you might have setup the source instrument incorrectly.It does no good to try to use LabVIEW to acquire a signal from a scope if you don't have the right input to it. You seem to be asking how to use LabVIEW to display a signal that is not there.

You could try asking for help in how to configure the source here but I think you might be better off asking Agilent tech support.

actually i post a message in the 'most active hardware boards' but it makes no difference when i click LabVIEW it show all message from different categories including mine; or maybe i miss out any steps in sending message.Because i am asking something on hardware but also related to software cause i need to get a real time signal [SGI] into LabVIEW exercise and the scales in the SGI for the real time signal plays an important role too,both must be correct cause they are connected if i make a correct scales setting for the scope but my SGI did not, when i run the exercise nothing will be shown on the SGI so i am actually asking 'graph scales'.The scope i know i have to depend on myself but i hope if someone happen to know and tell me scales should take into what consideration and etc.and i see people asking question on their RF instrument or scope too so i ask in the forum i think there should be nothing wrong in my connection for the scope and signal generator cause i can get result for my another exercise previously but i am unfamiliar with the generator and my teacher is often not around so i seek help from the forum without knowing i shouldn't post my question here. My apology.

I think there are language problems going both ways.

Can you answer with a simple yes/no whether or not you are able to setup the scope and signal generator manually (No LabVIEW) to display the signal?

If you answer yes, then take note of the vertical and horzontal settings of the scope. You will then have to duplicate these settings with the instrument driver. The graph being displayed on the VI should match what is on the scope. You might also want to use some of the lower level functions in the instrument driver instead of always calling the top level example. You will have more control and the better response since won't be resetting the scope with each iteration of your while loop.
