我正在使用N6705B porwer分析仪为我的被测设备供电,然后测量功耗。
由于我需要确定应用程序的开始/结束时间,我需要使用数字端口(后面板上的8针连接器)并将它们配置为数字输入。 我正在寻找的是在示波器视图上显示数字端口的波形(信号)以及电压/电流/功率信号。 但我没有找到实现它的方法。 即使我可以将此数字端口用作触发输入,也会很好。 实际上,我可以将数字端口配置为Trigger In,但这还不够。 因为在数据文件记录器菜单中,没有选项将此端口设置为触发事件,而只是设置运行/停止键或BNC或其他选项。 因此,如果我们既无法在示波器上看到数字端口信号,也无法将其设置为触发事件,那么它们的用途是什么? 他们似乎毫无用处。 任何帮助表示赞赏。 以上来自于谷歌翻译 以下为原文 I'm using a N6705B porwer analyzer to supply power for my device-under-test and then measure the power consumption. Since I need to determine the start/finish time of my application, I need to use Digital ports (8-pin connector on back panel) and configure them as Digital In. What I'm looking for is to show the waveform (signal) of Digital ports on the scope view along side with voltage/current/power signal. But I didn't find a way to accomplish it. It would be nice even if I could use this Digital ports as the Trigger inputs. Actually, I can configure Digital ports as Trigger In, but that's not enough. Because in Data file logger menu, there is no option to set this ports as the trigger event, but just Run/Stop key or BNC or other options. So, if we can neither see the digital port signals on scope, nor setting them as trigger events, what's their usage? they seem to be useless. Any help is appreciated. |

嗨,您可以通过SCPI命令将端口中的触发设置为数据记录器的触发器。
那个命令是TRIG:DLOG:SOUR。 如果将其设置为EXT,它将触发BNC触发器或任何设置为触发器的外部引脚。无法查看仪器示波器视图上数字引脚的值。 我可以提交这个作为可能的增强功能。 你可以做的唯一事情就是轮询引脚以查看其中一个引脚何时在各级之间转换(这是它们的用法)。 如果您想进一步讨论,请与我们联系。 以上来自于谷歌翻译 以下为原文 Hi, You can set the trigger in ports as a trigger for the datalogger via a SCPI command. That command is TRIG:DLOG:SOUR. If you set it to EXT, it will trigger on either the BNC trigger in or any of the external pins set as a trigger in. There is not a way to look at the values of the digital pins on the scope view of the instrument. I can submit this as a possible enhancement though. The only thing that you can do is poll the pins to see when one of them transitions between levels (this is their usage). Let me know if you would like to discuss this further. |
