Hi,

I am new to NanoVNA and the NanoVNA saver software. I really like the tool, especially the software that allows me to obtain frequency sweeps over a wide band with high resolution. I have a noob question -- When using the NanoVNA software, I use the calibration assistant to establish a 1-port calibration. Then I perform a sweep. I save the .cal and .s1p files. I am wondering, does the .s1p contain calibrated or uncalibrated data?

Best regards,
Omar
