  • 如何打印出仪器内部的校准常数表

    大家好,我花了数年时间研究8340/41。在我的生活中,我不能记住如何打印出仪器内部的校准常数表。我已经仔细阅读了这些信息的手册,但没有快乐。这里有没有人知道如何做到这一点(或者知道如何......我也会这样做。)谢谢!Len 以上来自于谷歌翻译 以下为原文Hello All,I spent years working on the 8340/41's.I can't, for the life of me, remember how to print out the Calibration Constants sheet that is included inside the instrument.I have scoured the manuals for that info, but no joy.Does anyone here know remember how to do this (or know how... I'll take that too.)Thanks!Len

  • HP 86290B扫描振荡器频率参考值最高可达18.8伏

    我有一个带选件H08的HP 86290B。该扫频振荡器插头的频率从2 GHz到22 GHz。但是,使用我的DVM测量时,设备背面BNC连接器的频率参考值最高可达18.8伏。我认为应该产生大约1伏/ GHz的输出,这样电压应该高达22.0伏?然而,我检查了输出频率,它在刻度结束时确实达到了22 GHz。 以上来自于谷歌翻译 以下为原文I have an HP 86290B with option H08. The frequency of this sweep oscillator plug goes from 2 GHz to 22 GHz.However, the frequency reference from the BNC connector on the back of the unit only goes up to a maximum of 18.8 volts when measured using my DVM. I thought it was supposed to produce an output of about 1 volt/GHz so that the voltage should go up to 22.0 volts?I checked the output frequency, however, and it does go to 22 GHz at the end of the scale.

  • 怎么测量不确定度

    任何人都可以了解HP8753D网络分析仪的测量不确定度规范;上个月,我们公司租用了HP8753D网络分析仪,配有HP85032B校准套件,用于测量我们产品的反射参数性能。在查看该分析仪的性能规格时(使用带N型连接的指定校准套件),反射测量不确定度在S11幅度= 1时表示为0.02。这是从技术规格手册第4页复制的,并以红色圈出附件。这似乎是一个非常大的不确定性,特别是在阻抗方面:S11 = 0.999相当于100k欧姆S11 = 0.979相当于4k7欧姆这个0.02 S11幅度不确定性相当于阻抗的96%不确定性?当然,在实践中,这两个单元都非常准确地测量了它们。我们是否错误地解释了这些规范?任何帮助表示赞赏。先谢谢你,乔希 以上来自于谷歌翻译 以下为原文Can anyone shed some light on the measurement uncertainty specifications for a HP8753D Network analyser; Last month our company rented a HP8753D Network analyser complete with HP85032B calibration kit to measure the reflection parameter performance of our product. When looking at the performance specifications for this analyser (using the specified cal kit with N type connections) the reflection measurement uncertainty is stated as 0.02 for S11 magnitude = 1. This is copied from the technical specifications manual page 4, andcircled in red in the attached file. This seems be a very large uncertainty, particularly in terms of impedance: S11=0.999 equates to 100k Ohms S11=0.979 equates to 4k7 Ohms This 0.02 S11 magnitude uncertainty equates to a 96% uncertainty in impedance? In practice of course, both are measured very accurately by this unit. Have we interpreted these specifications wrongly? Any help is appreciated.
