我正在收集超过 100k FastFrame 图像（100 帧，每个帧有 15k 点），使用摘要模式并使用 ni-visa 通过 python pyvisa 收集它们。

错误如下：

严重
系统内存不足。有些结果可能不完整。要进行补救，请减少记录长度或删除一项或多项分析功能，例如数学、测量、总线解码或搜索。

之后，我可以断开连接，再次连接，发送更新窗口的命令，但无法查询任何内容。我怀疑这与 MSO56 RAM 或通信队列上的内存泄漏有关。*RST、CLEAR、LCS 和 FACTORY 等命令不能修复错误。

糟糕的解决方案。

使用电源按钮重新启动示波器有效。

我应该在问题中添加这一点，但需要大约 2 分钟并且不是一个优雅的解决方案。
