Network Analyzer labview program

[arthur51189]

My grid is going to be a lot smaller than 100 x 100. When i said that it was just arbitrary. It's going to be more of a 10x10

See attached example for one way you can generate the file. For the headers just write out the headers before you go into the loop to write the data. I'm sure you can figure out how to write out the headers based on the way the 2D array's size is calculated.

Alright let me see what i can get. Thanks

Note: Not to lead you astray, but you can combine the 3 Replace Array Subset into one. You'd just need to build a 2D array out of the 3 individual 1D arrays. The VI I showed you was for demonstration.

With the 3 individual arrays I have for Magnitude, Phase and Frequency. How can I combine that into a 2-D array. I have a build array function but that just converts it to a 3-D array

And one more thing that kind of confused me on your sample program that part that says "Simulate network analyzer data" does that represent the section of code that i have my arrays for Magnitude Phase and Frequency? Because I wasn't sure what the 0, 10 or 20 meant.

Don't know how you'd be getting a 3D array. If you wire 3 separate 1D arrays into a Build Array function the output is 2D. See attached mod.

Yes, it does. The 0, 10, and 20 is just dummy data. Since I don't have your network analyzer.

When i ran your previous program, is the shift register necessary/

[smercurio_fc]

The shift register is present in both "collect NA data" and "collect NA data MOD". It's necessary in both. The reason is that you pre-allocate the array and you need to update the array in each iteration. The shift register will contain the current state of the array. If you just used a tunnel then you'd always be performing the replacement on the original array, rather than the current array.

I get an error when i connect my transpose to my replace array subset.
