您好我正在尝试使用Command Expert将DSOX3014A中的两个通道记录到USB设备上的文件中。
我的问题是示波器挂起了一些命令,按钮不响应新命令或按钮/开关,需要一个电源循环才能工作。 Agilent Connection Expert也会断开连接。 在某些(约8个)挂起中,示波器的电源循环没有帮助,PC也必须重新启动。 从我的调试到目前为止,似乎命令如:TRIGger:SWEep NORMal或:TIMebase:RANGe 5发出命令:WAVeform:DATA? 失败并显示消息VI_ERROR_TMO:发生超时| SCPI连接尝试超时我几天前更新了固件,但我是这种控制示波器的新手,所以我可能在Command Expert中有一些“明显”的错误......附上了Command Expert的截图。 的Eivind 以上来自于谷歌翻译 以下为原文 Hello I'm trying to log two channels from a DSOX3014A to a file on a USB device using the Command Expert. My problem is that the oscilloscope hangs on some commands, the buttons does not respond to new commands or buttons/switches and needs a power cycle to work. Agilent Connection Expert also looses the connection. In some (1 of ~8) hangs, a power cycle of the oscilloscope doesn't help and the PC must also be restarted. From my debugging so far it seems like commands like :TRIGger:SWEep NORMal or :TIMebase:RANGe 5 makes the command :WAVeform:DATA? fail with the message VI_ERROR_TMO: A timeout occurred | SCPI connection attempt timed out I updated the firmware a few days ago, but I'm new to this way of controlling the oscilloscope, so I may have some "obvious" fault in Command Expert... Have attached a screenshot of Command Expert. Eivind 附件

首先,我可能会遗漏一些东西,但是我在脚本中没有看到你实际上告诉范围“运行”或“数字化”。
如果你不告诉它运行,那么“WAV:DAT?”没有数据可用。 命令,所以它会超时。 其次,如果您只想将数据保存到USB,那么您不需要“:WAV:DAT?” 命令。 这些告诉范围将数据卸载到控制器(PC)。 人 以上来自于谷歌翻译 以下为原文 First, I may be missing something, but I don't see anywhere in your script that you actually tell the scope to "run" or "digitize". If you don't tell it to run, there's no data to get with the ":WAV:DAT?" command, so it will time out. Second, if you just want to save the data to the USB, then you don't need the ":WAV:DAT?" commands at all. Those tell the scope to offload the data to the controller (PC). Al |

nvywyerwer 发表于 2019-4-12 09:57 非常感谢您的回复。 我删除了digitize命令,因为它是第一个使示波器挂起的命令,但它可能与触发器组合:扫描正常命令。 根据你的回复,我发现你的一个matlab脚本和一些python脚本我设法用python做了我需要的东西(比commandexpert更容易调试)。 的Eivind 以上来自于谷歌翻译 以下为原文 Thank you very much for your reply. I removed the digitize command since it was the first which made the oscilloscope hang, but it was probably in combination with the trigger:sweep normal command. Based on your reply, one of your matlab scripts and a few python scripts I found I managed to do what I needed using python (easier to debug than commandexpert). Eivind |
