更改通道耦合时DSO6054A 221设置冲突错误

您好，我正在上面提到的示波器上运行最新的固件。
（6.16.0001）我试图通过'CHAN1：COUP AC'远程命令改变从DC到AC的通道耦合。
但是当我尝试通过ACE交互式窗口进行操作时，我收到了“221设置冲突错误”。
但是当我在示波器上手动更改它时，它让我这样做！
所以我不明白为什么我被阻止远程更改它。
我查阅了编程指南中的错误，但它只是参考波形子系统查询（页66）来讨论它。
我确实检查了'tiMEBASE：MODE？'
它被设置为'MAIN'。
任何想法为什么以及如何让它工作？
谢谢，rok

  Hello,

I am running the latest firmware on the above mentioned oscilloscope. (6.16.0001)

I'm trying to change the channel coupling from DC to AC by the 'CHAN1:COUP AC' remote command. But when I try to do it via the ACE interactive window, I get a '221 Settings conflict error'. But when I change it manually on the oscilloscope itself, it lets me do it! So I don't understand why I being blocked from changing it remotely. I looked up the error in the programming guide, but it only talks about it in reference to a waveform subsystem query (Page66). I did check the 'TIMEBASE:MODE?' and it is set to 'MAIN'.  

Any ideas why and how to get it to work?

Thanks,
rok
