Connection with LabView & 54600B Oscilloscope & Agilent E4438C

[Serina]

Hi,

    I am trying out an exercise on receiving the data from the 54600B oscilloscope into LabVIEW Analog and Digital Modulations VIs. Currently, i am trying out on ASK modulation and i want to grab the signal/waveform from the scope and display in the ASK modulation exactly the same as ASK modulation graph. And this ASK modulation will be used as SubVIs,which can be seen from the attachment to have a clearer image on the work.Can anyone please help me??This is very important because it is my project work..Thanks Alot!

Hi Serina,

Are you able to communicate with and obtain data from the Oscilloscope?  Are you specifically looking for information on how to manipulate the data once it is received?  Your post is fairly general, so if you can elaborate on what you have accomplished so far, and what specific areas you have questions on, then I may be better able to assist you.

Regards,

Lauren

Hi,

    I think i can understand what you are trying to say. Anyway thanks for replying i have been waiting for reply, i just manage to succeed in communicating the generator with the scope and get the square wave i want.. something like that ' |||---|||---||| '. but i need to set the ranges for the signal generator information graph, which is the graph displaying data from the RF instrument to scope and lastly into the internal PC LabVIEW exercise. no matter how accurate the graph i manage to get after adjusting by the oscilloscope, when i run the labview, the graph of the signal 'ranges all this related things' will affect the waveform in the scope and change into distorted or waveform i can't see. i have a hard time to find out what values to use for the ranges, position all this. I really hope you understand what i am talking about. Cause there are many question asking me to repeat or explain again and even point out i shouldn't post this question in the labview forum..

I assume you are referring to the "signal generator information graph" is a graph that is in LabVIEW. It appears that your VI has a place for you to set the position and range and all the setting you would have control of on your scope in LabVIEW. If you use those inputs, you should be able to acquire and display exactly what you are seeing on your scope. Also, you can change the scale of the graph in LabVIEW manually by double-clicking on any of the numbers and changing the scale or right-clicking and setting Auto-scale. I hope this helps.

Hi,

    yes, that's the graph i am talking about. I think you can see it the ranges and position beside the graph belong to it and have their 'default' setting of scales which is autoscale but i cannot see(or display another) the waveform in the graph when i run my exercise. So i have to set the scales manually instead of using the default scales. For a clearer explaination, eg. i set my scope and display a waveform i want, but when i run the exercise, not only the "signal generator information graph" did not display the desired waveform i want in addition, it affect and change the waveform in the scope too (some time too big and scope hang for a few sec or other waveform). that's why i have to set the setting of the "signal generator information graph" manually but i don't know in order to set the value of those ranges and position,what factor or condition i must take into consideration. I did know can change the scale, thanks 🙂 but i don't know how to set to a correct scales as i have failed for many times in displaying the waveform correctly both in scope and LabVIEW "signal generator information graph".

I have solve all the problems already.. Thanks anyway!
