||||
|ClampV| FIMV @ 10Ω All Channel|| Pass! |
|
||||
|ClampI| FVMV/FVMI @ 10Ω All Channel| | Fail! [Note3](#custom-anchor3) |
|
||||
|
||||
## 3. 问题
|
||||
|
||||
### 3.1 发现的问题
|
||||
|
||||
1. Force存在±10mV抖动 <a id="custom-anchor1"></a>
|
||||
|
||||
2. 取得正确的测量结果的流程较为复杂,需: <a id="custom-anchor2"></a>
|
||||
1. 在取得初始值前通过ATE_Debugger发送指令:newdpsfunc("newdpsinitvalue","enable");
|
||||
2. 上位机连接获取初始值
|
||||
3. 检查初始值无误后上传初始值至Zynq中
|
||||
4. 通过ATE_Debugger发送指令:newdpsfunc("newdpsinitvalue","disable");
|
||||
5. 执行测量
|
||||
|
||||
3. 在ClampI模式下(FVMV/FVMI),若Clamp值与Force值接近(如80mA档位Clamp60mA,Force70mA;2mA档位Clamp1mA,Force1.5mA)则Force输出与Sense管脚及对应信号链均会出现震荡,且在极端情况下震荡 ***可能不收敛*** <a id="custom-anchor3"></a>
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
### 3.2 原因分析
|
||||
|
||||
1. 初步推测由地平面噪声引入,整板均存在,影响Force输出稳定性
|
||||
2. ADC计算公式不同,现通过固件进行区分修正,导致需额外指令切换计算公式,猜测固件通过映射初始值进行转换
|
||||
3. 由于Clamp经过采样电阻后作为反馈输入运放构成Clamp电压,但其反馈、试探过程时间较长且可能导致不收敛,在这过程中输出电压不受控
|
||||
|
||||
## 4. 测试结论
|
||||
|
||||
Force存在噪声影响稳定性,Measure欲获得正确回读值需发送指令,过程较为复杂,Clamp除短路时生效外基本无实用意义
