在进行了一系列长时间的测试后，没有硬件或程序改变，34970A开始发出哔哔声并不断闪烁其前面板。
从测试设置中删除后，它在上电时报告错误913“模块报告的非易失性存储器故障”。
无论安装了哪个模块，重复上电时都会出现此错误。
较长的开机自检会发出“通过”消息，同时显示相同的错误信号。
最重要的是，该装置现在无法通过RS232
通信 - 不会返回具有已知良好串行端口连接和线束的ID。
闪烁的前面板和蜂鸣声尚未复制，因为原始测试情况仅用于测试目的 - 不适用于测试设备维修。
到目前为止，在擦除启动错误或其他情况后，使用手动输入值的前面板功能看似正常。
34901A模块中的继电器控制似乎是常规的。
34907A模块上的
电源电压似乎正常，安装后，两个输入端口字节的数据均可读取。
我将处理串口作为硬件修复问题。
错误913 ....这可能是其他地方损坏的结果？

以下为原文
After running a long series of tests, with no hardware or program altera
tions, the 34970A started beeping and flashing its front panel continually.
On removal from the test setup, it reported an error 913 "Module reported nonvolatile memory fault" at power-up.
This error at power-on is repeated, regardless of module(s) installed. The longer power-on self-test issues a 'PASS' message, while presenting the same error signal.
On top of this, the unit now fails RS232 communication - will not return ID with a known-good serial port connection and harness.
The flashing front panel and beeping have yet to be reproduced, as the original test situation is only available for testing purposes - not for test equipment repair.
So far, function from the front panel, using manually-entered values seem normal, after the start-up error is erased, or otherwise. Relay control in the 34901A modules seems regular. Supply voltages on a 34907A module seem normal, when installed and data is readable on both input port bytes.
I'll deal with the serial port as a hardware repair issue.
The error 913 .... is this likely the result of damage elsewhere?
