The nose-to-nose calibration theory can achieved the self-calibration of the sampling oscilloscope with whatever bandwidth.The early simulation study was focused on the key signal,kick-out pulse.We simulated from the different viewpoints,and the fully simulation aimed at a microwave diode sampler head was processed with PSPICE.The conclusion that kick-out is due to the leak of the strobe pulse when the sampler circuit is unbalanced.The simulation and experiment on NTN were discussed also.

N ose-to-nose校准技术可以对任意带宽的取样示波器进行自校准.早期的研究工作集中在对关键信号k ick-ou t脉冲的仿真.本文从不同的角度对微波二极管取样头电路进行了全面的仿真,得到了结论:k ick-ou t脉冲是由于在取样电路的不平衡时选通脉冲的泄漏造成的.并对NTN校准技术从仿真实验到物理实验做了介绍.

In this paper, the design and principle of a agile RF signal generator is introduced, and the key techniques including the API, delay line discriminator, frequency locked loop, frequency synthesis of single loop, frequency fast hop etc. are discussed. It has important significance in the design of high purity spectrum agile signal synthesizer and frequency synthesizer in military digital communication equipment.This paper put forward the API model with high performance and practicality, including model details and methods in application. It realizeed the design of one-loop frequency synthesizer ranging from 500MHz to 1000MHz by using delay line discrimination technique. Using the API model mentioned in this paper, the fractional spuriousness are reduced to the extent that the phase interpolation signal exactly matches the phase error. Through the use of precision DACs and carefully designed phase detector and sampler circuit, fractional spuriousness of about 75~80dB can be achieved.Phase noise improvement of one-loop frequency synthesizer,ranging from 500MHz to 1000MHz, is attained about 15dB to 20dB by using delay line discrimination technique.It can meet the test requirements of mobile communication system,frequency agile, radio confront and phase noise measurement applications.

本文介绍了一种射频频率捷变信号发生器的设计方案和工作原理,讨论了模拟相位内插(API)、延时鉴频器、锁频环、单环频率合成和频率快速跳变等关键技术。这对于高纯频率捷变合成信号源和军用数字通信设备中频率合成器的设计具有重要意义。本文提出了高精度实用化的API模型,包括实际运用中的模型细节和实现方法,实现了具有延时鉴频技术的单环500MHz~1000MHz频率合成器的设计。采用本文研究的API内插模型,小数分频的尾数调制寄生谱可以抑制到相位内插信号准确地匹配相位误差的程度。通过精密DAC的运用和精心设计相位检波器和取样器线路,尾数调制达到约75~80dB的抑制。采用延时线鉴频技术可以在500MHz~1000MHz单环频率合成器中获得15~20dB的相噪改善。设计结果满足移动通信系统、频率捷变,电子对抗和相噪等领域的测试需求。
