NanoVNA-H4 4 LCD 50KHz1.5GHz VNA HF VHF UHF UV Vector Network Analyzer g

  

NanoVNA-H4 4 LCD 50KHz1.5GHz VNA HF VHF UHF UV Vector Network Analyzer g. 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.

Reserved UART interface for DIY expansion. Lightweight ABS shell keeps the device well protected. Omputer 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. 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.

ABS Shell: 75mm x 133mm x 18mm (excluding protrusions) 2. Measurement Frequency: 50KHz 1.5GHz 3. RF Output: 0dbm (±2dB, fundamental wave) 4. We recommend that you try again after 3-4 days. Always believe we can figure things out with communication, if it comes to return, the pacakge must be intact and the same as you receive.
