PXA N9030A功率校准错误

问答对人有帮助，内容完整，我也想知道答案 0 在正常工作1-2周后，我们在N9030故障装置的生产中遇到了问题。这些单元始终在2-6 dB范围内读取高功率。我们启用了自动对齐功能，仪器未报告任何错误。手动启动“立即对齐”不会更正校准。通过对仪器进行电源循环可以恢复N9030的性能。关于发生了什么的任何想法？以上来自于谷歌翻译以下为原文 We are having issues in production with the N9030 failing units after working properly for 1-2 weeks. The units always read high power in the 2-6 dB range. We have auto-align enabled and no errors are reported by the instrument. Manually initiating an "Align All Now" will not correct the calibration. The N9030 performance can be recovered by power cycling the instrument. Any ideas on what is going on? 0

答案对人有帮助，有参考价值 0 嗨 - 我们需要有关确切情况的更多信息，以便我们为您提供帮助。首先，您正在测量什么样的设备？什么是功率电平，信号类型（脉冲，CW，通信信号）？信号的频率是多少？请提供PXA序列号。我在下面的消息中添加了评论，我不明白你在告诉我什么。 “在正常工作1-2周后，我们在使用N9030发生故障的设备时遇到了问题。”+失败的“单位”是您的被测设备？而不是我们的PXA单元？+“这些单元总是在2-6 dB范围内读取高功率。”+当PXA测量您的DUT时，测量结果比预期高2-6 dB？+“我们有自动 - 对齐已启用且仪器未报告任何错误。“+如果自动对齐失败，通常会看到”立即对齐所有需要“或者会弹出错误，例如RF对齐失败。按System，Show Errors查看任何错误。如果您现在看到任何错误以及这些错误是什么，请告诉我们。+“手动启动”立即对齐“将无法更正校准。”+什么是“校准”？你的意思是在执行Align All Now之后，DUT信号仍然没有正确测量，或者PXA仍然无法自动校准？+“N9030的性能可以通过重启仪器来恢复。有关正在发生的事情的任何想法？“+也许PXA的输入信号太大，因为您选择了输入衰减器设置高到足以降低信号电平，并且仪器ADC过载。通常，您会在屏幕底部看到一条消息，显示输入过载：ADC超出范围。您是否看过这个？+ +然后通过循环仪器电源，默认衰减设置为10 dB，此衰减设置现在允许ADC超出范围？+ +或者，循环功率导致必须再次设置测量，以及导致问题的分析仪上的任何设置都不再存在？+如何设置我的PXA和信号源以查看此问题？问候 - 以上来自于谷歌翻译以下为原文 Hi - We need additional information on what exactly is happening so we can help you. First, what kind of device are you measuring? What is the Power level, type of signals (pulsed, CW, communications signals)? What is the frequency of the signal? Please provide the PXA serial number. I have added comments in your message below, where I do not understand what you are telling me. “We are having issues in production with the N9030 failing units after working properly for 1-2 weeks.” +The “units “ that are failing are your devices under test? And not our PXA units?+ “ The units always read high power in the 2-6 dB range.” +When the PXA measures your DUT, the result is a measurement 2-6 dB higher than expected?+ “ We have auto-align enabled and no errors are reported by the instrument.” +If auto align fails, usually you see “Align Now All Needed “ or an error will pop up such as RF alignment failed. Press System, Show Errors to see any errors. Let us know if you now see any errors and what these errors are.+ “Manually initiating an "Align All Now" will not correct the calibration.” +What is the “calibration”? Do you mean after performing the Align All Now, the DUT signal still does not measure correctly, or that the PXA still fails an auto alignment?+ “The N9030 performance can be recovered by power cycling the instrument. Any ideas on what is going on?” +Perhaps the input signal to the PXA is too large because you have chosen an input attenuator setting hot high enough to reduce the signal level, and the instrument ADC is overloaded. Usually you see a message at the bottom of the screen that says Input Overload: ADC Over range. Have you seen this?+ +Then by cycling instrument power, the default attenuation setting is 10 dB, and this attenuation setting now allows the ADC over range to not occur?+ +Or, cycling power results in having to set up the measurement again, and whatever setting on the analyzer that caused the problem, is no longer present?+ How can I set up my PXA and a signal source to see this problem?
