射频芯片自动测试平台设计

Design of Automatic Testing Platform of RF Chip

射频芯片具有频率高的特点,传统的测试方法是通过信号源、频谱仪、矢量网络发生器等设备分别连接射频模拟接口测试,不同链路测试就需要重新连接线缆,测试效率低。本文介绍了基于开关矩阵的射频芯片自动化测试平台,采用GPIB接口连接和Pascal语言编程,结合射频开关矩阵灵活切换的优点,搭建自动测试平台,实现了对射频芯片多参数的自动测试,具有测试效率高和测试精度高的特点。

RF chip has the characteris.The traditional test method is to connect the RF analog interface test by the signal source,the frequency spectrum instrument,the loss network generator and other equipment.The different link tests need to reconnect the cable,and it is lowly efficient.This paper introduces an automatic test platform for RF chip based on switch matrix.Using GPIB interface connection and Pascal language programming.And the advantages of flexible switching based on RF switching matrix.The automatic test platform would be established to realize the automatic test of the multiple parameters of the RF chip.This plan has the advantages of high test efficiency and high test precision.
