一种自动DLVA测试系统设计

A Design of Automatic DLVA Test System

检波对数视频放大器(DLVA)广泛应用于现代雷达和电子战设备中,对动辄成百上千的DLVA,利用人手动测试DLVA的指标,测试时间长,记录数据量大,同时还要进行繁杂的数据运算。提出了一种自动DLVA测试系统的设计方法,并进行了自动测试验证。测试结果表明,该自动DLVA测试系统可极大地缩短测试时间,实现自动的数据记录和运算,节约了测试成本,缩短了DLVA调试周期。

Detection logarithmic video amplifier （DLVA） is used in radar and electronic warfare e quipments extensively today.Usually hundreds of DLVAs need to be dealt with, but if the DLVA indexes are tested manually,it will cost too much time,and the data size will be large,the muhifa rious data operation need to be conduct.This paper gives a design method of automatic DLVA test system, and performs the automatic test validation.The test results indicate that this automatic DL VA test system can cut down the test time greatly, realize automatic data record and operation, save the test cost, shorten the debugging period.
