Features 1、VECTOR NETWORK MEASUREMENT CAPABILITIES: Vector network analyzer provides perfect vector network measurements in a compact, handheld, stand alone, 2.8 inch LCD, portable, battery powered or USB powered Package. 2、MEASUREMENT FREQUENCY OF 900MHZ: 2.8 inch vector network analyzer can support measurement frequencies up to 900 MHz using the odd harmonic extension of the si5351. tx Rx methods measure the complete S11 and S21 parameters. 3、METAL SHIELDED: Antenna analyzer is designed with metal shielding to reduce external interference and improve measurement accuracy. Direct output of the si5351 in the 50k‑300MHz frequency range provides better than 70dB of dynamics. 4、UPGRADED DESIGN: MF HF VHF UHF antenna analyzer provides better than 60dB of dynamics in the extended 300M‑600MHz band and better than 50dB of dynamics in the 600M‑900M band. Network analyzer can give you the best using experience. 5、PC CONTROL SOFTWARE: For NanoVNA vector network analyzer is compatible with original equipment (OE), formed and functional with simple and practical PC control software, we can export touchstone (snp) files for various radio design and simulation software through PC software.
