TDR (time domain reflectometry) allows measuring cable length and discontinuities.NanoVNA-QT software – supports advanced calibration methods and custom calibration kit parameters allows S parameter export.High dynamic range: 90dB (V2 Plus4), achieves similar results as professional instruments can measure duplexers.Compared to other NanoVNA versions, V2 Plus4 and V2 Plus4 Pro do not use harmonics for measurements, improving performance significantly.New from-scratch design by HCXQS/NanoRFE.Gift box size: about 24x14x3cm/9.45*5.51*1.NanoVNA V2 (S-A-A-2) is a 4GHz vector network analyzer (VNA) capable of measuring antennas, filters, duplexers, and amplifiers. Measure S parameters, voltage standing wave ratio, phase, delay, Smith chart, time domain analysis.

Number of calibration points: 101 (fixed)ĭisplay tracking: 4, mark: 4, setting save: 5

Power supply: USB 5V 200mA, built-in 1950mAh battery, maximum charging current 1A USB interface: USB type-C communication mode: CDC (serial) (When using harmonic measurement, it is necessary to pay attention to the error caused by the nonlinear transformation of the fundamental wave) Optimized PCB layout, accommodating 1950mAh battery, used for more than 8 hours reserved UART interface for easy DIY expansion.ĪBS shell: about 75mm x 133mm x 18mm/2.95*5.24*0.71inch (excluding protrusions) Reproduce the designed power management circuit, further reducing the power supply noise, reducing the USB power supply interference, reducing the charging current, and protecting the battery.Ħ. Resolve the abnormality of NanoVNA-H before 6MHz.ĥ. When the fundamental wave is used, the CH0 output level is increased to 0dBm, and the reflection measurement is more accurate.Ĥ. The electric bridge is optimized to make full use of the harmonics of Si5351, and now the 5th harmonic can be used to measure to 1.5GHz.ģ. The 4-inch full-view LCD screen adds DC dimming, which makes it clearer when used outdoors and more comfortable for indoor use.Ģ.
