How to design oscilloscope..need idea, advice and suggestion...

[as_united88@yahoo.com]

hello...

im student..so i'm new in LabVIEW...so i have use LabVIEW 8.6 and NI cDAQ-9178 to connect between hardware.. and my PC..., now i have final project..i must design digital oscilloscope using labview, but i have several problem...

1) how to design  design oscilloscope

2) i have design simple block diagram to display wave..but stil have a litte bit problem, from this block diagram...how i want to develop the another part such design time base, vertecal control, horinzontal control, capture the wave...and so on..., i was reserch the previous oscilloscope in labview and i desgin again by reffer the this previous....but still not function....

i hope, someone can help me...to give me idea, advice or suggestion to me to complete my fnl project...plz....now i state my design....and any recommend and suggetion from someone i accept....thank you very much

A quick peek at the NI-Scope Soft Front Panel should give you some ideas about how to put this together.  

  

Actually one of the nicer apps I've seen

I would also suggest starting with the LabVIEW examples. If you search for "oscilloscope" you will find an example that you can start with. It's an old example, and it should be rewritten to use an event structure and perhaps a producer-consumer architecture, but it can give you some ideas.

before that i want to say thank you very much above your idea...but  i have search..oscilloscope in example.....i have got one....when i open using LabVIEW8.6...that have still icon i cant understant.....can u explain wat icon this, how the icon function....

a) CheckDevice.vi

b) Chose the signal.vi

one more  thing can i design the my project by refer this block diagram..., in my project i was use DAQ 9178 to connect hardware to my Digital Oscilloscope base on PC....can or not

I'm sorry I do not understand what icos or icons you are asking about.  You may need to post a more detailed response in your native language and duplicate the post using google translate to help us understand.

ok...you have send one example oscilloscope..to me, i  have looking and it is very great..ok my question...

1) how to develop/ design the some button for example volt division, frequency divison, cursor..and many other like button in real oscilloscope

2) how this button can that be functionly when i build in my schematic block diagram using LabVIEW 8.6

3) it is have any toturial or some guide to me in complete my final project...

i hope you can help me in my problem....thank you

Those are SubVIs.  Double-click them to open them and see the code inside.  These are very basic to LabVIEW coding, if you don't understand them you need to study some LabVIEW tutorials before you try to code your project.  The CDaq 9178 is just a chassis that holds DAQ cards.  Whether or not it will work to make a DSO depends on what modules are in it.

Are you sure you will be allowed to turn in a final project for school that is just a copy of an example???
