1.5Ghz 4-Inch Vector Large-Screen Network Analyzer Nanovna-H4 Antenna Shortwave
Features 1. 4-inch full-view LCD screen adding DC dimming it can be seen more clearly when used outdoors and it is more comfortable to use indoors. 2. Optimized the bridge to make full use of the harmonics of Si5351 and now can use the 5th harmonic to measure up to 1.5GHz; 3. When the fundamental wave is used the CH0 output level is increased to 0dBm and the reflection measurement is more accurate; 4. Solve the abnormality that NanoVNA-H appeared near 6MHz before; 5. The redesigned power management circuit further reduces power noise reduces USB power interference reduces charging current and protects the battery; 6. Optimized PCB layout accommodate 1950mAh battery use more than 8 hours; 7. UART interface is reserved for DIY expansion; 8. A new ABS shell is made by opening the mold which is light and convenient and protects the machine; Specification ● ABS shell: 75mm x 133mm x 18mm (excluding protrusions) ● Measurement frequency: 50KHz ~ 1.5GHz ● RF output: 0dbm (±2dB fundamental wave) ● Frequency accuracy:
