??Upgrade DIY Antenna Tools?:Compare to the old VNA,the new vector network analyzer with the ABS shell support time domain analysis function(TDR).Support connecting windows computers and usb -c smart phone,you could operate it with bigger screen.
??Handy NanoVNA?:2.8 Inch TFT display on the tiny antenna analyzer is more clear and practical.Built-in a 450mAh battery,portable with USB powered,the screen will display the battery usage.
??50MHz-900MHz Frequency Algorithm?:This NanoVNA can use the odd harmonic extension of the si5351 to support measurement.70dB(50kHz-300MHz),50dB(300M-600MHz) and 40dB (600M-900MHz) enable extended firmware.
??High Measurement Accuracy?: The HF VHF UHF UV VNA Antenna Analyzer has a metal shield which reduce the external interference and improve the measurement accuracy.
??S12/S22 Measurement?: The TX/ RX method measures the complete S11 and S21 parameters. If you need to get S12 and S22 through the Pocket VNA, you need to manually replace the transceiver port wiring.
