The devil is in the details with such a simple-sounding statement. Attach it how? There are 2 ports on the NanoVNA, each with a center conductor and an outside conductor (called, shield, ground, body, etc.) The inductor (DUT) has a single conductor with 2 ends. So, exactly how do you connect those 2 ends to the NanoVNA ports? Considering there is also an option of leaving certain ports, wire ends, or conductors (center/shield) disconnected, there are more than 10 possible options.
Then, once some sort of connection is made between inductor and VNA, which measurement option (menu choice) do you select on the NanoVNA? S11, S21, shunt, thru, etc. This decision adds more complexity.
For those experienced/ trained in using VNA¡¯s and deciding such things for multiple different types of DUT¡¯s, these may be such basic questions as to be assumed inherently obvious. But they are not inherently obvious to the new VNA users attracted to forums such as these.
