920L NanoVNA-H Digital Measuring S Parameters Standing Ratio Phase Delay Chart Features: OOTDTY Measuring S Parameters, Standing Ratio, Phase, Delay, Smith- Chart. The is designed to reduce the external and improve the measurement accuracy. Small and portable, easy to use, this project aims- to provide RF- gadget- but useful instrument for enthusiast-. The PC control- software can export Touchstone- (snp-) files-, which can be used for various radio design and simulation software. Latest HW3.6 antenna with card slot design, for recording data up to 32GB, great for data storage and sharing-.
