ベクトル・ネットワーク・アナライザー Bode100


Bode 100 offers two VNA modes:vector02_large.jpg

  • In the Frequency Sweep mode Bode 100's fully integrated internal measurement circuits assess the DUT's gain/phase and impedance/reflection.
  • The Frequency Sweep (External coupler) mode allows using of external measurement circuitry such as amplifiers and directional couplers for special impedance/reflection measurement requirements (e.g. measurement of broadcast antennas).

The frequency sweep may be undertaken using a linear or logarithmic method to produce Bode plots in the whole frequency range. The results may be displayed in different formats as magnitude, phase, real part, imaginary part, group delay ...
Also polar plots for gain and impedance measurements as well as Smith charts for reflection measurements are available.
