Network vector channel analyzer

摘要: In a vector network analyzer with transmitting and, receiving side, each including downward mixing super heterodyne receiver, high voltage power supply for providing an accelerating is arranged in series second controllable lower output so that unavoidable variations the acceleration can be controlled. The connected to of phase and frequency discriminator by way amplifier low-pass filter. has two inputs, one downwardly mixed side signal other provided reference oscillator having constant frequency. As millimeter wave backward used whose drifting temperature changes or aging compensated control supply, which derived from discriminator.
