Description: The 4-inch full-view LCD screen has added DC dimming, and it can be seen more clearly when used outdoors, and it is more comfortable to use indoors. Optimized the bridge to make full use of the Si5351's harmonics. Now the 5th harmonic can be used to measure to 1.5GHz. When the fundamental wave is used, the output level of CH0 is increased to 0dBm, and the reflection measurement is more accurate. Solve the previous abnormality of NanoVNA-H near 6MHz, Optimized PCB layout, accommodating 1950mAh battery, more than 8 hours of use. Reproduce the designed power management circuit, further reduce power noise, reduce USB power interference, reduce charging current, and protect the battery. Specification: Box size: 133X75mm/5.2X3.0" Set weight: 0.37 KG Reserved UART interface, convenient for DIY expansion; The new ABS shell is made when the mold is opened, which is light and convenient, and protects the machine; The packaging is exquisite to provide guarantee for the safety of subsequent transportation. Package Includes: 1. NanoVNA host*1 (including 4-inch touch screen, 2000mAh battery) 2. 15cm SMA male to male RG316 RF cable *2 3. SMA female to female connector *1 4.
