when the Nano VNA (connected to Nano Saver) first powers up, the sweep is 50KHz to 3 GHz. I have an antenna connected to port 1. I change the sweep to 900 to 930 MHz and click on Set Reference Sweep, but the graphs still display the default frequencies: 50 KhZ TO 3 GhZ. How do I get the graphs to display same frequencies as the sweep ?
