Hi James,
I just want to place a marker in labview code, let me explain it more specifically.
Now I want to do beadpull test on a device and get the beadpull graph using the labview and agilent 8720es network analyzer.
The beadpull test can make you detect the device's internal electric field change as bead travels inside the device. The bead travel inside the device is driven by a step motor. Using the 8720es to measure the s11, then you need to get the lowest frequency at each step point, which is defined as f. The first step point lowest frequency is defined as f0. The value I want to calculate is Ez=(f-f0)/f0, so there should be a graph on the front panel of labview, the graph x axis is the position of the beam and the y axis is the Ez. Now I already have the beadpull labview example code using the agilent PNA 5230c analyzer, when I try to program according to it using my 8720es, I find that the vi libraries in their drivers are quite different. I don't know how to program for it. So can you help me to do that?
I have attached the example code using PNA 5230C. Just open the test folder and double click the test project file. In the project, click the standingwave and beadpull.vi, and you will understand what I mean.
