WebJust click that and save the raw data from the TDR. How to plot TDR plots using Data from the TDR in Matlab: Open the file tdrplots.m. Replace the file name ‘wire.dat’ with your ‘filename.dat’. Replace the word ‘wire’ with your ‘filename’ wherever you find it in the program. The program gives you 2 plots (1) Reflected Voltage. WebA TDR isn't really a TDR anymore when it comes to devices like the FieldFox. It's more of an FDR. It's been a while since I've read up on the theory, but if you take a return loss plot and do an FFT on it, the data should look like a TDR plot. Maybe.
