![]() 1-800MHz or, with Ultra mode enabled, level calibrated up to 6GHz. However, it should not be seen as an alternative for a high-end VNA like the SNA5002A from the Siglent SNA5000A series. Thanks Cathy, Im sure the spectrum analyzer branch of NanoVNA-App is in capable. With this VNA the use of higher accuracy calibrators allows for higher precision of measurements.Īll in all, this is a powerful VNA for a limited budget. The output power may decrease when frequency is lower than 1 MHz or higher than 3 GHz. Above 3GHz the performance decreases with increasing frequency causing the port isolation to only be 50 dB at 6 GHz.įurthermore, below 1 MHz, the performance decreases with decreasing frequency and the effective dynamic range decreases to 70 dB at 100 kHz. These remarks are as follows:ĭue to some structural limitations the S12 isolation is 10 dB worse than that of the S21 parameter. 2021 Upgraded NanoVNA- NanoVNA V2 Plus4 is a new hardware vector network analyzer with a 4 inch 480 x 320 sensitive touchscreen measuring the S11 Reflection coefficient and the S21 Transmission coefficient of a high frequency network accurately, solidly built, easy to calibrate and set up. ![]() Although the LibreVNA hardware isĭesigned to be a VNA, the general hardware architecture is so similar to that of a spectrum analyser that simple two-channel spectrum measurements can also be performed.ĭue to this being an open source VNA, there are some limitations in the design. Thanks to two measurement ports this vector network analyser can be used to measure the complete set of reflection and transmission coefficients (S11/S12/S21/S22). It is able to do 10000 point dual-port measurements within one second and has an effective dynamic range of 100 dB. ![]() The PCB has 3 ADC's and a FPGA for all the signal signal processing. 300 kHz to 6 or 8.5 GHz operation High speed, up to 5500 dual-port S-parameters per second > 10 000 S11 + S21 per second Quad RX four-receiver architecture for best accuracy Up to 124 dB dynamic range at 10 Hz bandwidth 0. The VNA is an RF frontend with some processing power but everything else is handled in the PC application. The LibreVNA is an open source USB based vector network analyser with 2 ports.
