PNA N5232A警告消息接收器A过载

问答对人有帮助，内容完整，我也想知道答案 0 亲爱的，我希望有人在遇到此问题之前可以帮助澄清：我对我遇到的PNA警告消息有疑问，“警告：接收器A超载”。我会接受这一点，因为进入接收器A的功率超过了它的伤害等级。我的型号是N5232A，规格称损坏等级为+ 15dBm。我已经定制了前面板，因为我希望在900MHz时提高RF功率。并弹出错误消息。因此，我取下连接到前面板接收器A的电缆，并将其连接到功率传感器，以查看RF功率是多少。 RF仅为-2dBm。我假设每当某个功率压缩级别发生时会弹出此消息，而不是高于+ 15dBm，但我无法从数据表中获取详细信息。我不确定我们是否会遵循N5232A的这个规范？任何想法将导致此警告消息的输入功率级别是什么。我的N5230C没有看到这样的问题。感谢大家！！以上来自于谷歌翻译以下为原文 Dear all, i hope anyone encounter this issue before can help to clarify: I have a question regarding the PNA warning message I encountered with, “WARNING: Receiver A is overloaded”. I would take that as the power going into the Receiver A exceeded its damage level. My model is N5232A, and the specs says the damage level is at +15dBm. I have customized the front panels as I wish to boost the RF power at 900MHz. And the error message pop up. So I removed the cable connected to the front panel Receiver A in, and connect it to a power sensor to see what is the RF power. The RF is only -2dBm. I assume this message will pop up whenever a certain power compression level happen, rather hitting above +15dBm, however I couldn’t get the details from datasheet. I am not sure shall we follow this spec for N5232A? any idea what’s the input power level that will cause this warning message. my N5230C did not see such issue. thanks everyone!! 0

答案对人有帮助，有参考价值 0 只要接收器功率超过操作级别（非损坏级别）并将接收器置于压缩状态，就会出现此消息。消息发生在损坏等级以下约15 dB处。因此，测试端口的工作电平大约为+13到+15 dBm（操作意味着数据良好）; 损坏等级为+27至+30 dBm，具体取决于型号。这些是测试端口。耦合器的损耗为13-16 dB，因此A接收器的功率在达到最大工作电平时大约为-2 dBm。在这种情况下采取的数据是可疑的。首选关闭此消息; 如果达到该过驱动水平，则还有另一个优先选择关闭源功率。我会向我们的帮助文件人员注意这一点，以清理细节。以上来自于谷歌翻译以下为原文 This message occurs whenever the receiver power exceeds the OPERATING level (not damage level) and places the receiver into compression. The message occurs approximately 15 dB BELOW the damage level. Thus, the operating level of the test port is appoximately +13 to +15 dBm (operating means the data is good); the damage level is +27 to +30 dBm depending upon model number. These are test port referred. The coupling has 13-16 dB loss, so the power at the A receiver is on the order of -2 dBm when it reaches it's max operating level. Data taken in this condition is suspect. There is a preference to turn off this message; there is another preference to turn off the source power if this overdrive level is reached. I'll note this to our helpfile guy to clear up the details.

答案对人有帮助，有参考价值 0 这是来自帮助文件的文本，它基本上说的是Joel所说的（压缩的，可能是不准确的数据）。：http：//na.tm.agilent.com/pna/help/latest/System/PNA_Preferences.htm#SourceOFFOverload我试图让这个更加具体，但是在给定的模型，各种频段的功率水平，它变得非常复杂，所以我们选择模糊而不是过分混淆和可能不准确。以上来自于谷歌翻译以下为原文 Here is the text from the help file, which essentially says the same thing that Joel said (compressed, and potentially inaccurate data). : http://na.tm.agilent.com/pna/help/latest/System/PNA_Preferences.htm#SourceOFFOverload I tried to make this more specific, but it got real complicated with given models, power levels in various frequency bands, etc. So we chose to be vague rather than overly confusing and potentially inaccurate.
