Product Features

The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz. The 50k-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic. The extended 300M-600MHz band provides better than 50dB of dynamics, and the 600M-900M band is better than 40dB of dynamics. Support for connecting mobile phones using Type C-Type C data cable (included). Built-in rechargeable lithium battery for easier use. Metal housing for easier and safer use and more beautiful.
