Agilent是否为E9304A-H18传感器提供-H84校准?
我问,因为我的经理希望用-H84选项校准一个传感器而不是我们目前发送的两个传感器(8482A和8481A),以节省资金。
虽然E9304A-H18覆盖了频率范围,并且具有更好的SWR,但我的反对意见如下:1。
E9304A是一款二极管传感器,通常不像热电偶传感器那样线性。
它具有低功率路径,其具有比高功率路径更高的不确定性。
如果使用低功率路径,则必须将这些更差的不确定性与由-H84标准传感器校准的任何其他功率传感器一起使用。
我的论点有效吗?
是否有更多原因我不应该为二极管传感器进行-H84选项校准?

  Does Agilent provide an -H84 calibration for E9304A-H18 sensors?  I ask because my manager wants to have that one sensor calibrated with the -H84 option instead of the two sensors (8482A and 8481A) we currently send, to save money of course.  Although the E9304A-H18 covers the frequency range, and has better SWR, my argument against it is as follows:
1.  The E9304A is a diode sensor, which are typically not as linear as thermocouple sensors.
2.  It has a low-power path which will have higher uncertainties than the high-power path.  These worse uncertainties will have to be used with any other power sensors calibrated by this -H84 standard sensor, IF the low-power path is used.  

Is my argument valid?  Are there more reasons I should not get an -H84 option calibration for a diode sensor?

安捷伦不为任何E930x系列传感器提供H84选件。
原因就在于你已经提到的:不确定性较高。
安捷伦确实为一些更精确的848xA(已停产)848xD和新型N848x传感器提供H84选项。
所有H84选配传感器都旨在最大限度地降低校准中的测量不确定度。
因此,安捷伦在这些传感器方面提供的产品有限。
这意味着你必须做更多的传感器切换,以覆盖你发现的所有波段。
但这有助于确保计量应用中较低的测量不确定度。如果您需要更多帮助,可随时拨打免费的安捷伦响应中心电话1-800-829-4444。
我希望这有帮助。

  Agilent does not offer a H84 option for any of the E930x series of sensors.  The reason for this is what you have already mentioned: the higher uncertainty.  Agilent does offer H84 options for some of the more accurate 848xA (discontinued,) 848xD, and the new N848x sensors.  All of the H84 optioned sensors are designed to mimimize the measurement uncertainty in a calibration.  For this reason Agilent has a limited offering in these sensor.  This means that you have to do more of the sensor switching to cover all bands as you have found out. But this helps ensure a lower measurement uncertainty in a metrology application.

If you need more help with this you can always call the free Agilent Response Center at 1-800-829-4444.  I hope this helps.
