Make sure the latest firmware is uploaded to the analyzer. See the Downloads section.

* The AntScope software is able to plot graphs in Time Domain Reflectometer (TDR) mode when AA-30/AA-54/AA-170 is connected to the computer. Since the resolution of the TDR graph is proportional to the maximum operating frequency of an analyzer, much better results are obtained by using AA-230 ZOOM, AA-600, AA-1000 or AA-1400.
