Hence here other technique is employed which measures incident wave, reflected wave and transmitted wave. This is not possible to do at high frequency. There are various equipments which performs this calculation such as volt meter, current meter, sine wave generator etc. Network Analyzer : As we know network analyzer is used to measure impedance.Īt low frequency, we can simply divide voltage and current to obtain impedance. This tutorial also provides links to difference between scalar and vector network analyzers. Vector Network Analyzer (VNA) measurements, VNA calibration etc. Vector Network Analyzer basics, VNA transmitter and receiver block diagrams, The connection to the Android device is done by USB, you will require an OTG adaptor (not sold by WiMo).Vector Network Analyzer tutorial | VNA tutorial The Android app is called 'BlueVNA' and is available in the Google Play Store. THis software is available for Windows, MAC and Linux, a new Android app is also available. The recommended software is 'VNA/J' the same software as already known from the other MinIVNA products. Software upgrades are also provided via the USB interface.
Power supply is done by the USB interface, an external power supply is not required. The analyser can be used as a low power HF generator as well. Impedance (Z) can be measured from 1 to 1000 Ω, the dynamic range is up to 70 dB.
The results can be displayed or stored as Smith diagram.ĭue to the calibration with an optional calibration kit (open, short, load, see arrticle 21010.SMA) the measurement results are precise and easily reproducible.
The device works as a vectorial analzer, suitable to do typical quadrupole measurements of S11 and S21 parameters. As a two-port system the MiniVNA-Tiny can be used for transmission measurements on band filters or amplifiers. The MiniVNA-TINY is a network analyzer and does not only allow measurement of SWR and impdances of antennas. Remarkable is the very large frequency range from 1 to 3000 MHz. The MiniVNA-TINY is a very compact antenna analyzer with USB connection.
