The resulting impedances can be plotted in AWR DE, and exported to a text file. This table is in a format that allows it to be directly imported into AWR DE as a data file for use and plotting. Simply select the graph or table to be plotted and click: Graph Export Trace Data. Then select the file location and file name of the resulting text file. In these files a line starting with "!" denotes a comment. Adding comment lines are useful for showing what values are being imported into the project. Table 2.3 shows a text file with impedances produced by the circuit shown in figure 2.51. The first few lines beginning with "!" are added for clarity. To keep the number of lines in this table small a 10 MHz frequency increment is chosen in the project options, resulting in 21 frequencies being used. In practice, many more frequencies would be used. Table 2.3. Bandpass T impedances of figure 2.51 !
