Latest NanoVNA NanoVNA-F VNA HF VHF UHF Vector Network Antenna Analyzer + 4.3 inch IPS LCD + Metal Case New laser typing case is arriving, new 1.5GHz measurement frequency on sale~~~ support measurable frequency to 1.5 GHz, default setting 1 GHz, accurate measurement up to 1.35GHz. Product Description: NanoVNA-F Mini Vector Network Analyser is a product based on the Open Source Project of NanoVNA (https://ttrf.tk/kit/nanovna/). The RF part is consistent with the original version (NanoVNA-F uses harmonic spread measurement frequency to 1 GHz ). NanoVNA-F hardware functions include and are not limited to the following improvements: 1. Use 4.3-inch IPS TFT LCD screen, with a larger view angle and can be seen clearly in strong outdoor light. 2. Switch to large capacity 5000mAh lithium batter y, standby time is longer, and expand a USB interface. Usually, it can be used as a rechargeable treasure when the instrument is not used. 3. The IC is charged by high current 2A, and the charging time is shorter. 4. Change to larger and better operating wave wheel. 5. Switch to a power switch with a greater sense of operation and a better sense of operation. 6. Support Chinese and English menu switching; 7. Upgrade the user program by virtual U disk. 8. Standard aluminium shell to protect SMA head and reduce the interference of external electromagnetic wave to instrument. 8. Software open source github.com/flyoob/NanoVNA-F The hardware block diagram of NanoVNA-F is as follows NanoVNA-F measurement range is 50k-1GHz . The harmonic spread measurement frequency of the output signal of the clock chip SI5351 is 1000MHz. At 600M-1GHz, the dynamic range of S11 is 40dB (standing wave ratio is less than 1.02). At the same time, a metal shield is designed for the RF front-end, so that the dynamic range of S21 is better than 60dB in the whole frequency band. Features : Dimensions: 14CM * 7.5CM * 2CM (length, width and height) Measuring Frequency: 50kHz ~ 1000MHz RF output: - 13 DBM (maximum - 9 dbm) Frequency accuracy: lt; 0.5 ppm Port SWR: lt; 1.1 Display: 4.3 inch IPS TFT (800x480) USB Interface: USB Type-C Communication Mode: CDC (Serial) Power consumption: USB 5V 200mA, built-in 5000mAh battery, theoretical life of 18 hours, maximum charging current 2A Output capability: 5V/1A, supporting Android and Apple phones Number of calibration points: 101 Number of scanning points: 101 Display Tracking: 4, Mark: 4, Settings Save: 5 Scanning time: about 1.9s/time (50kHz-1000MHz full frequency band) Measurable S parameters, voltage standing wave ratio SWR, phase diagram, group delay, Smith circle diagram... ; 19.0Wh (about 5000mAh after conversion) large capacity lithium battery Designing a metal shield for the RF front end, allowing the S21 to have a dynamic range better than 60dB over the full frequency range power bank fuction: 5V/1A , Supporting Android and Apple Mobile Open route length test: NanoVNA-F S11 parameter, SWR standing wave ratio test UV9D antenna U-ba
