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 an outgoing 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. If you have any suggestions for future releases, please feel free to contact us as well.\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003e \u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/b\u003e\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eImpedance: 50Ω\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eTest Port Connector: SMA, female\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eNumber of Test Port: 2\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eFrequency Range: 100kHz to 6GHz\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eFrequency Accuracy: \u0026lt;2ppm\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eNumber of Measurement Points: 2 to 4501\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eSpeed 2-port - 4000 pts: \u0026lt;500ms (IFBW=50 kHz )\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eMeasurement Bandwidths: 10Hz to 50kHz\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eDynamic range (IFBW 10Hz): \u0026gt; 95 dB to 3GHz ,  \u0026gt; 50 dB to 6 GHz (Note 1)\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eMeasurement parameters: S11, S21, S12, S22\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eReflection directivity: \u0026gt; 40 dB (after calibration) (Note 2)\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eOutput power: -40 dBm to 0 dBm (Note 3)\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003ePower Supply: DC 5V, 1.5A(USB powered, or 3.5mm connector)\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003ePower consumption: approx. 7W.\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eInterface: USB type-C\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eSupported Operating System: Windows, Linux\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eExternal Reference Input: SMA female; 10 MHz;\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eExternal Reference Output: SMA female; 10 MHz or 100MHz;\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eFurther measurement options: Simple spectrum analyzer(Lack of mirror suppression and slower speed), Signal generator(Not precisely calibrated)\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003e \u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px;\"\u003eFeature:\u003c\/span\u003e\u003c\/b\u003e\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003e\u003c!--[if !supportLists]--\u003e1. \u003c!--[endif]--\u003eVector Network Analyzer\u003co:p\u003e\u003c\/o:p\u003e\u003c\/p\u003e\u003cp class=\"MsoNormal\"\u003eLibreVNA is a USB based full 2-port vector network analyzer designed by Jankae.
