The update time of each measurement point is 1 millisecond. The standard frequency resolution is 100 KHZ. Options are 1 Hz 001. Narrow band or long delay devices provide accurate measurements. Microwave devices are often used to measure characteristics, but traditional measurement vector networks can only be used to measure continuous excitation, such as pulse excitation measurement is necessary.
Continuous wave (CW) is a challenge to use narrowband receiver vector network for general line in frequency domain and pulse signal in frequency domain exceeds infinite line. In this paper, by analyzing the working principle, how to configure the AV3620 vector network is introduced. Therefore, the pulse excitation is measured correctly in the parameter S of the test piece.
