When it comes to value for money, the new generation of VNAs is unbeatable. This page was translated from cho45’s NanoVNA User Guide.Vk3ye dot com - Things you can do with a Nano VNA Calibrate according to the calibration method.To do firstīefore you can use it, you must first calibrate it. First, calibrate as follows. In either case, the input is converted to an intermediate frequency of 5kHz. The signal is converted from analog to digital at 48kHz sampling. Digital data is signal processed by the MCU. Note that there is always a fundamental wave input, especially when checking the amplifier gain. The local frequency of NanoVNA is 50kHz to 300MHz. For higher frequencies, use harmonic mode. The fundamental wave is not attenuated even in harmonic mode. The usage modes for each frequency are as follows. NanoVNA measures the reflection coefficient and transmission coefficient for 101 points in the frequency band to be measured. The following items that can be calculated from these can be displayed. VNA (Vector Network Analyzer) measures the frequency characteristics of reflected power and passing power of a high frequency network (RF Network). Start using NanoVNA What you need to work ![]()
