这里为了不识洋文的群友们方便,我们做的这个使用说明
意思就是问你对测试结果满意不,这里有什么满意不满意的,只能选yes才能继续,不然又回到测试界面
yes后1.80v测试一轮结束。进入下一轮
以此类推,测试完几个电压
VPUmin = 1.80V (allowed voltage interval: from 1.44V to 2.30V)
VPUmax = 5.00V (allowed voltage interval: from 4.00V to 5.50V)
TTL H levels test:
VHmin = 1.80V (allowed voltage interval: from 1.44V to 2.30V)
VHmax = 5.00V (allowed voltage interval: from 4.00V to 5.50V)
到下面这里开始测试负载电流了,需要短接jp1
输入万用表数字点ok继续
后面针脚测试一样操作,做完以下几个
VCCP voltage levels test:
VCCPmin = 1.80V (allowed voltage interval: from 1.71V to 1.89V), Iload=75.00mA
VCCPnom = 5.00V (allowed voltage interval: from 4.90V to 5.10V), Iload=75.00mA
VCCPmax = 7.00V (allowed voltage interval: from 6.65V to 7.35V), Iload=75.00mA
VPP1 voltage levels test:
VPP1min = 1.80V (allowed voltage interval: from 1.64V to 1.91V), Iload=75.00mA
VPP1nom = 17.00V (allowed voltage interval: from 16.66V to 17.34V), Iload=75.00mA
VPP1max = 26.00V (allowed voltage interval: from 24.70V to 27.30V), Iload=75.00mA
VPP2 voltage levels test:
VPP2min = 1.80V (allowed voltage interval: from 1.64V to 1.91V), Iload=75.00mA
VPP2nom = 17.00V (allowed voltage interval: from 16.66V to 17.34V), Iload=75.00mA
VPP2max = 26.00V (allowed voltage interval: from 24.70V to 27.30V), Iload=75.00mA
这个耗时好精力,需要耐心的
最后一步就是测试内部频率源看是否正常,需要万用表有测试频率功能或者外接示波器(大多数人没有这个,可以直接点ok跳过以便完成整个校准过程)
