LibrevnaVNA 100kHz-6GHz USB Based Full 2-port Vector Network Analyzer Connect to Computer

Description 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 please fully understand the possible limitations before buying this machine Specification Impedance50ΩTest Port ConnectorSMA femaleNumber of Test Port2Frequency Range100kHz to 6GHzFrequency Accuracy2ppmNumber of Measurement Points2 to 4501Speed 2 port 4000 pts500ms IFBW 50 kHz Measurement Bandwidths10Hz to 50kHzDynamic range IFBW 10Hz 95 dB to 3GHz 50 dB to 6 GHz Note 1 Measurement parametersS11 S21 S12 S22Reflection directivity 40 dB after calibration Note 2 Output power 40 dBm to 0 dBm Note 3 Power SupplyDC 5V 1 5A USB powered or 3 5mm connector Power consumptionapprox 7W InterfaceUSB type CSupported Operating SystemWindows Linux Only 64 bit software is available for now External Reference InputSMA female 10 MHz External Reference OutputSMA female 10 MHz or 100MHz Further measurement optionsSimple
