Communication Signals In The Electromagnetic Environment Simulator Hf Background Signal Generator Design

The background signal simulator adopts the mode of "virtual instrument" and carries out the thoughts of "Software is the instrument" and simulates the real signal electromagnetic environment by means of loading and changing the parameters real-timely and dynamically in the current spot This simulator has high flexibility.This article discusses the arbitrary waveform generation of HF wave band basing on ISP technology .Its main content includes three parts: the ISP logic control x the memory of data and the D/A conversion .In these parts the article introduces the design method on ISP technology, the design principle of the high_speed circuit in data memory, analyzes the problems in the debugging and how to solve them. The background signal of HF wave band achieves the expectant targets in the debugging of the signal electromagnetic environment simulator of the wireless communication system.
