Select and enter your lowest frequency (e.g., 140 MHz).
NanoVNA-QT is an open-source PC software designed to control and interact with the S-A-A-2 VNA. The software provides a user-friendly interface for configuring the VNA, collecting data, and visualizing results. With NanoVNA-QT, users can: Avoid charging-only cables
Here are two real-world projects where the PC software outshines the standalone unit.
Performing calibration (OSL - Open, Short, Load) is actually easier in the software, but it can be confusing.
