visa

Good Morning,

My name hani mustika, I am a last years student in an Engineering School

I have a question, I'm making the wavelet system with the input signal is cardiac signal; and the output is normalized energy. I use a simulator of the different cardiac signal source, first using cardiac signals originating from outside labview (using Visa), then the second one uses the heart signal simulator derived from additional toolkit labview, I'm confused why the results differ? Are there any errors in the Visa?

I have to confess that I have no idea what you mean.  They're different because they come from different sources and have different data?

Your conversion of the VISA Read to an array is just silly. Obviously, a single point read is different than an entire waveform from the simulator.

different source and the same data, first source is ekg simulator ( from outside labView and use Visa to Connect between LabView and ekg simulator). Second source is Ekg simulator from inside labView  (Uses biomedical Toolkit).

i wil display 2 picture of source ekg

are you help me for this problem?

[haniadi]

Do you have a solution for my problem?

[Dennis_Knutson]

I have no idea what that box is. You need to acquire a waveform before passing it to the wavelet function. You can acquire multiple points with a for loop.

You already marked my answer as the solution. Why do that and keep asking questions?

We also have no idea what is actually being returned by the external simulator. The only thing you show is conversion to a scalar.

I'm just totally confused.  It sure looks like two different sources to me?  Do you even know the output waveform is the same?

I'm thinking it could be a language barrier.  Maybe you can post better in your native language?
