This page was translated from cho45’s NanoVNA User Guide. 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. It has: A metal case An internal 18650 Li-Ion battery (not included due to shipping restrictions) A charge status indicator for the battery & charging from a computer's USB jack Beefier controls for slewing the cursor and markers A 4. 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. The nanoVNA 2 Plus4 differs from the previous versions in several ways. The 4' NanoVNA-H 4 can be entered into update mode by pressing and holding the multifunction switch before turning it on, and the screen remains black after entering engineering mode.

NanoVNA measures the reflection coefficient and transmission coefficient for 101 points in the frequency band to be measured. If the 2.8' NanoVNA-H firmware version is higher than 0.2, you can use the menu 'CONFIGDFURESET AND ENTER DFU' to enter the update mode. 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
