我在E4417A功率计上使用E9320 E系列功率传感器。
我正在使用带外部触发的连续触发模式，当外部触发信号发出脉冲时，我看到功率计在A通道和B通道上都有所改变。 当我停止外部触发信号时，A通道按预期停止更新，但B通道继续更新。 似乎B通道继续获取数据并更新显示，即使它应该等待外部触发。 有谁知道发生了什么？ 我看不到通道B的单独触发配置，似乎只有一个全局触发设置，所以我不明白为什么A通道和B通道没有触发相同的方式。 以上来自于谷歌翻译 以下为原文 I am using E9320 E-Series Power Sensors on an E4417A power meter. I am using continuous trigger mode with external trigger, and when the external trigger signal is pulsing, I see the power meter updating on both the A channel and B channel as I expect. When I stop the external trigger signal, the A channel stops updating as expected, but the B channel continues to update. It seems that the B channel is continuing to aquire data and update the display, even though it should be waiting for the external trigger. Does anyone know what is going on? I cannot see a separate trigger configuration for channel B, there only seems to be one global trigger setting, so I do not understand why the A channel and the B channel are not triggering the same way.

E4417A只有一个外部触发输入，可响应TTL电平触发。
如果您在两个通道中使用峰值功率传感器，此触发信号通常会触发通道A和B; 例如E9320系列传感器。 如果处于带有外部触发的连续触发模式，则应在显示屏的上部中央部分看到上升沿或下降沿方波。 当功率计接收到触发时，方波上的箭头将移动，表明功率计已被触发。 此触发信号将触发两个通道，因为您无法将它们分开。但是如果您有一个平均传感器，如N8480系列，或连接到通道B的E9300或E4410系列，该通道将保持自由运行，您将获得 更新显示。 即使通道A没有被Ext触发器触发也是如此。这回答了你的问题或者有任何帮助吗？ 以上来自于谷歌翻译 以下为原文 The E4417A has only one external trigger input that responds to a TTL level trigger. This trigger signal will normally trigger both channels A and B if you are using peak power sensors in both channels; for example the E9320 series sensors. If you are in the Continious Trigger mode with External Trigger you should see a rise edge or a falling edge squarewave at the upper center part of the display screen. When the power meter receives a trigger the arrow on the squarewave will move showing that the power meter has been triggered. This trigger signal will trigger both channels as you can't seperate them. However if you have an average sensor such as a N8480 series, or a E9300 or E4410 series connected to the Channel B that channel will stay in Free Run and you will get updates to the display. This is true even if Channel A is not being triggered by the Ext trigger. Did this answer your question or be of any help? |

你好大卫，我有两个E9320系列传感器，一个在通道A上，另一个在通道B上。你在发表的所有内容中，我都在我的仪器上观察过，但有一个例外：如果我关闭进入外部的信号
输入，通道A将无限期地等待下一个触发脉冲。 通道B似乎在大约两秒后超时并触发自身。 当我第一次观察到这种行为时，我担心通道B不会以与通道A相同的方式触发外部脉冲。 似乎两个通道都在外部输入上正确触发，唯一的区别是通道B似乎有超时而通道A没有。 以上来自于谷歌翻译 以下为原文 Hello David, I have two E9320 series sensors, one on channel A and one on channel B. Everything you state in you post, I have observed on my instrument, with one exception: if I turn off the signal that is going into the external input, channel A will wait indefinitely for the next trigger pulse. Channel B seems to time out after about two seconds and trigger itself. When I first observed this behavior, I was worried that somehow channel B was not triggering on the external pulse the same way channel A was. It seems that both channels are triggering correctly on the external input, the only difference is that channel B seems to have a timeout while channel A does not. |

我们试图通过触发来复制你遇到的问题，而你是正确的;
通道B仍然会触发。 它不应该这样做。 它似乎是固件中的一个错误。 我们正在将此问题提交给研发团队进行审核。我们还针对此问题开发了一个解决方案，您可以使用它来防止将来发生这种情况。 但请注意，当您在通道A和通道Ba中使用两个E932x功率传感器时，每次重启E4417A时都必须完成此操作。）使用两个E9320系列传感器连接器预设E4417A b）转到“触发器”，更改 “Acqn B”到“Cont Trig” - 必须将通道B更改为连续触发器，具有外部源FIRSTc）转到“Setting”，将“Source”更改为“Ext”d）然后，将“Acqn A”更改为“Cont” Trig“我希望这种解决方案适合你。 以上来自于谷歌翻译 以下为原文 We tried to duplicate the problem you are having with the triggering, and you are correct; Channel B will still trigger. It should not be doing this. It appears to be a bug in the firmware. We are submitting this issue to the R&D development team for a review. We have also developed a work-around to this issue that you can use to prevent this from occuring in the future. But be aware that this work-around must be done every time you reboot the E4417A when you are using two E932x power sensors in Channel A and Channel B. a) Preset the E4417A with two E9320 series sensors connector b) Go to “Trigger” , change the “Acqn B” to “Cont Trig” – MUST CHANGE CHANNEL B to CONTINUOUS TRIGGER WITH EXTERNAL SOURCE FIRST c) Go to “Setting”, change the “Source” to “Ext” d) Then, change the “Acqn A” to “Cont Trig” I hope that this work-around works well for you. |
