100KHZ - 6 GHZ USB based full 2 port VNA SWR ANALYZER RADIO ACCESSORIES
LibreVNA (TM) is a USB based full 2-port vector network analyzer designed by Jankae. Using 3 ADCs to sample data simultaneously and using FPGAs for signal processing, it is capable of scanning over 10,000 points of full dual-port
measurements in less than 1 second. The ultra-low noise power supply design and the use of 16bit ADC, together with the precision CNC's aluminum shielded housing, achieve up to 100dB of effective dynamics. Many aspects are already
comparable to lab-grade VNAs, but this is still a work-in-progress project. Some design features may not be perfect, especially the performance will drop when the frequency is higher than 3GHz


Specifications
Impedance - 50 ohms
Test Port Connector - SMA, female
Number of Test Port - 2
Frequency Range - 100kHz to 6GHz
Frequency Accuracy - <2ppm
Number of Measurement Points - 2 to 4501
Speed 2-port - 4000 pts - <500ms (IFBW=50 kHz )
Measurement Bandwidths - 10Hz to 50kHz
Dynamic range (IFBW 10Hz) - > 95 dB to 3GHz > 50 dB to 6 GHz (Note 1)
Measurement parameters - S11, S21, S12, S22
Reflection directivity - > 40 dB (after calibration) (Note 2)
Output power - -40 dBm to 0 dBm (Note 3)
Power Supply - DC 5V, 1.5A(USB powered, or 3.5mm connector)
Power consumption - approx. 7W.
Interface - USB type-C
Supported Operating System - Windows, Linux, MacOS. (Only 64-bit software is available for now)
External Reference Input - SMA female; 10 MHz;
External Reference Output - SMA female; 10 MHz or 100MHz;
Further measurement options - Simple spectrum analyzer (Lack of mirror suppression and slower speed)
Signal generator - (Not precisely calibrated)

Note 1:Due to structural limitations, S12 isolation is 10dB worse than S21. Above 3GHz, the performance decreases with increasing frequency, and the port isolation is only 50dB at 6GHz. Below 1MHz, the performance decreases with decreasing
frequency, and the effective dynamic decreases to 70dB at 100kHz.
Note 2:The use of higher accuracy calibrators allows for higher precision measurements.
Note 3:The output power may decrease when the frequency is lower than 1MHz or higher than 3GHz.
