NanoVNA Plus is a portable handheld vector network analyzer (VNA) designed to measure reflection and transmission coefficients. Originally designed by edv555. After several upgrades, NanoVNA Plus is the highest performance version at present, with the measurement frequency range upgraded to 50KHz-2.7GHz, and the performance is better than the previous 1.5GHZ old version Bandwidth: 50KHz-2.7GHz Dynamic range: 80dB (50KHz-900MHz) 60dB (900MHz-1.5GHz) 50dB (1.5GHz-2.7GHz) Reflection coefficient: SWR: Less than 1.1 Frequency accuracy: Less than 0.5 ppm Frequency stability: Less than 2.5 ppm Scan points: 101 Built-in 1000mAh battery Micro-SD supports up to 32GB, and only supports SPI mode.
