怎么在没有冗长扫描的情况下摆脱零扫宽的Meas Uncal？

3184 EXA

问答对人有帮助，内容完整，我也想知道答案 0 在测试辐射发射时，我正在使用N9010A EXA的“Meas Uncal”。远程设置来自ETS-Lindgren的tiLE6！程序如下：零跨度QP测量，RBW = 120kHz，VBW = 300kHz，扫描= 200ms（10001pts）。当从Tile6！更改扫描=自动时，EXA显示扫描= 269秒（如果我记得正确）。 Tile6！应用程序将长扫描视为无响应并终止其操作。当设置扫描= 200秒时，仍然有“Meas Uncal”。我无法忍受再试一次。感谢您提前提出建议。以上来自于谷歌翻译以下为原文 I am having the "Meas Uncal" from N9010A EXA while testing radiated emissions. The remote setting was from ETS-Lindgren's TILE6! program as following: QP measurement in zero span, RBW=120kHz, VBW=300kHz, sweep=200 ms (10001pts). When changed sweep = auto from Tile6!, EXA displayed sweep = 269 seconds (If I remembered correctly). Tile6! application treated the long sweep as no response and terminated its operation. When set sweep = 200 seconds, still got "Meas Uncal". I could not stand to try any longer sweep. Thank you for any advise in advance. 0

答案对人有帮助，有参考价值 0 嗨 - 当EXA处于零跨度时，没有自动扫描时间的设置。如果是TILE6！程序已发送命令将扫描时间设置为自动，将显示错误消息“设置冲突：扫描时间不能在零扫宽时自动耦合”，扫描时间将保持在200毫秒。此外，当处于零跨度时，将扫描时间更改为269秒然后再更改为200秒将不会生成Meas Uncal指示。但是，如果跨度更改为2.57 MHz并且扫描时间设置为自动耦合，则自动耦合扫描时间将为269秒。如果您随后将扫描时间更改为200秒，则会显示Meas Uncal，因为分析仪扫描速度比自动耦合扫描时间快。这是正确的行为。因此，检查以确保在TILE6中设置sweep = auto时！ EXA范围保持设置为0 Hz（零扫宽）的程序。如果跨度设置为非零值，则需要向ETS-Lindgren咨询此问题。他们对“sweep = auto”的定义可能与安捷伦的“扫描时间=自动耦合”不同。 “没有反应”的行为就是TILE6！程序应该能够处理。 TILE6！程序可能会超时。如果程序将扫描时间设置为较高值，则还应更改其超时值以允许更长的扫描时间。这是您需要与ETS-Lindgren讨论的问题。问候 - 以上来自于谷歌翻译以下为原文 Hi - When the EXA is in zero span, there is no setting for auto sweep time. If the TILE6! program had sent the command to set sweep time to auto, the error message “Settings Conflict: Sweep Time cannot be auto-coupled while in Zero Span” would have been displayed and the sweep time would have remained at 200ms. Also, when in zero span, changing the sweep time to 269 seconds and then to 200 seconds will not generate a Meas Uncal indication. However, if the span was changed to 2.57 MHz and sweep time set to auto coupled, the auto coupled sweep time would be 269s. If you then change the sweep time to 200s, a Meas Uncal will be indicated because the analyzer is sweeping faster than the auto coupled sweep time. This is proper behavior. Therefore, check to make sure that when you set sweep = auto in the TILE6! program that the EXA span remains set to 0 Hz (zero span). If the span is being set to a non-zero value, then you need to consult ETS-Lindgren about this issue. Their definition of “sweep = auto” might not be equivalent to Agilent’s “sweep time = auto coupled”. The “no response” behavior is something that the TILE6! program should be able to deal with. The TILE6! program is probably timing out. If the program is setting the sweep time to a high value, it should also change its timeout value to allow for the longer sweep time. This is an issue you will need to discuss with ETS-Lindgren. Regards -
