Features: - With DC dimming method, 4 full-view LCD screen can be seen more clearly for outdoor uses, and more comfortable for indoor uses. - Optimized Electric Bridge: Making full use of the harmonics of Si5351, it can use the 5th harmonic to measure up to 1.5GHz. - When fundamental wave is used, the output level of CH0 is increased to 0dBm, making reflection measurement more accurate. - Solved the abnormality of NanoVNA-H when operating at around 6MHz before. - Redesigned power management circuit reduces power noise, USB power interference, and charging current. - Improved PCB layout. - Reserved UART interface for DIY expansion. - Lightweight ABS shell keeps the device well protected. -Computer software supports control and real-time display. And it support for exporting snp files for various radio design and simulation software. - As a measuring device, accuracy is of great importance. Simple calibration parts are included in the package. We have calibrated the product`s dual ports before delivery. When your measurement conditions change (for example, switching from a narrower calibration bandwidth to a wider measurement bandwidth with an extension cable measurement), you need to re-calibrate. After calibration, it is saved as setting 0, which can be used directly at the next boot, or it can be saved to the other 4 saved items through recall when needed.
