NanoVNA-F Portable Handheld Vector Network Analyzer SWR Meter 50KHz-1000MHz 4.3 Inch IPS TFT Digital Display Touching Screen Shortwave MF HF VHF Antenna Analyzer

Features:
Use 4.3-inch IPS TFT LCD and resistive touching screen, with a larger view angle and can be seen clearly in strong outdoor light.
Switch to a large capacity 5000mAh/3.7V lithium battery, longer standby time, and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.
The Lipo charing IC to be changed to IP5306 (with 2A high charing current), making the charging time shorter.
Use a larger and better operating level.
Use a larger and better operating power switch.
Support Chinese and English menu switching.
Upgrade the user program by virtual U disk (16MB SPI flash memory inside).
Standard aluminium housing to protect SMAhead and reduce the interference of external electromagnetic wave to instrument.
The NanoVNA-F measurement range is 50k-1GHz. Use the harmonic of the clock chip SI5351 to measure frequency up to 1000MHz. At 600M-1GHz, the S11 has a dynamic range of 40dB (the standing wave ratio is less than 1.02).
The RF front end is designed with a metal shield that allows the S21 to have a dynamic range better than 60dB over the full frequency range.
