Measurement Range: 70dB(50KHz-300MHz), 60dB(300M-900MHz),40dB(900MHz-1.5GHz). Equipped with TDR function, helps to analyze the stability, transient and steady state performance of the system vector analyzer can connect computer by PC software NanoVNASaver, and it can extracts the data for display on computer, and for saving to files. export (snp) files for radio design and simulation software through PC software. The TX/ can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring Built-in a metal , antenna analyzer ham radio can reduce external interference and measurement accuracy. color:Black Material:Metal Package Contents: 1 set x Spectrum analyzer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
