[问答] 带N8481A传感器的E4416A功率计不会校准
109 传感器 电缆
分享
我一直在使用带有多个传感器的E4416A EPM-P功率计,包括8481A,8482A,8481D,E9304A,E4412A和E4413A。
我使用11730A(米色)电缆将这些传感器连接到仪表。
我最近购买了2个新传感器,N8481A和N8482A。
N8482A按预期运行,但N8481A不会校准,因为它会出现“可疑数据”错误。
为了验证传感器的操作,我将其连接到另一个功率计(E4418B EPM)并按预期运行。
然后,我使用E9288A(蓝色)传感器电缆将传感器重新连接到E4416A,它可以正常工作。
我更新了E4416A固件以使用新的N84xx传感器。
除了使用E9323A峰值功率传感器外,我没有使用蓝色传感器电缆。
是否应始终使用蓝色电缆与E4416A?

  I have been using an E4416A EPM-P power meter with several sensors, including the 8481A, 8482A, 8481D, E9304A, E4412A, and E4413A. I connect these sensors to the meter using an 11730A (Beige) cable. I recently purchased 2 new sensors, the N8481A and N8482A. The N8482A operates as it should, however the N8481A will not calibrate as it gives the "Questionable Data" error.

   To verIFy the operation of the sensor I connected it to another power meter (E4418B EPM) and it operates as it should. I then reconnected the sensor to the E4416A using an E9288A (Blue) sensor cable and it functions properly.

   I have updated the E4416A Firmware to operate with the new N84xx sensors. I have not used the blue sensor cable except when utilizing the E9323A Peak Power Sensor. Should the blue cable be used at all times with the E4416A?

您好,11730A(米色)电缆可与848x系列,N848x系列,E441x系列和E930x系列功率传感器配合使用,配备E4418 / 9B或E4416 / 7A功率计。
只有E932x系列功率传感器和E4416 / 7A功率计才需要E9288A(蓝色)电缆。
因此,任何新的热电偶功率传感器(N848x)都可以与灰色电缆一起使用,它们也可以与蓝色电缆配合使用。
但蓝色电缆不是必需的。
但是,正如您所提到的,请确保您的旧功率计更新为最新固件,以便他们能够识别新的N848x系列功率传感器。我不知道为什么您的N8481A仅使用蓝色电缆与E4416A配合使用
,而不是使用灰色电缆。
我怀疑这条灰色电缆有问题。
如果仍在保修范围内,您可以将其发送至安捷伦服务中心进行结账。

  Hello,

The 11730A (beige) cables can be used with the 848x series, N848x series, E441x series, and the E930x series of power sensors with the E4418/9B or E4416/7A power meters.  The E9288A (blue) cables are only required with the E932x series of power sensors and the E4416/7A power meter.  So any of the new thermocouple power sensors (N848x) will work fine with the grey cables, and they will also work with the blue cables.  But the blue cables are not required.  But, as you mentioned, be sure that your older power meters are updated to the latest firmware so that they can recognize the new N848x series of power sensors.

I don't know why your N8481A is only working with the blue cable with your E4416A, and not working with the grey cable.  I would suspect a problem with this grey cable.  If it is still covered under warranty you could send it to the Agilent Service Center for a checkout.

我试过多条电缆无济于事。
我重新刷新固件,但也没有帮助。
我注意到当使用灰色电缆并打开电源参考时,N8481A指示-30 dBm。
似乎E4416A无法正确识别传感器,为什么它与蓝色电缆一起使用是一个谜。
我将远程查询仪表以获取有关传感器的信息。

  I have tried multiple cables to no avail. I re-flashed the firmware and that didn't help either. I did notice that when using the gray cable and with the power ref turned on the N8481A indicated -30 dBm. It seems as though the E4416A does not recognize the sensor properly, why it does with the blue cable is a mystery. I am going to remotely query the meter for information about the sensor.

嗨,让我知道这是怎么回事。
使用带有灰色电缆的N8481A时,1 mW参考电压的测量功率是-30 dBm +/-约0.1 dB?
如果是这种情况,则E4416A可能正确读取N8481A中的检测电阻。
你试过多根灰色电缆吗?
蓝色电缆与灰色电缆具有相同的连接,另外还有一些用于E932x传感器峰值测量功能的连接。
因此,平均传感器N8481A的两根电缆之间应该没有差异。

  Hi,

Let me know how this turns out.  When you use the N8481A with the grey cable is the measured power from the 1 mW reference exactly -30 dBm +/- about 0.1 dB?  If this is the case then the E4416A may be reading the sense resistor in the N8481A in-correctly.  Have you tried multiple grey cables?  The blue cables have the same connections as the grey cables, plus some additional connections for the peak measurement capabilities of the E932x sensors.  So there should be no differance between between the two cables for the averaging sensor N8481A.

我尝试了6种不同的灰色电缆,没有用。
两条蓝色电缆我都做了。
是的,仪表显示-30 dBm +/- .1 dB。
也许电缆的阻力是一个因素。
我的N8482A适用于所有电缆。

  I have tried 6 different gray cables, none work. Both blue cables I have do work. And yes the meter indicates -30 dBm +/- .1 dB. Maybe the resistance of the cables is a factor. My N8482A works fine with any cable.

我尝试使用固件版本为A1.05.00的E4416A和带有蓝色电缆和灰色电缆的N8481A进行设置。
我没有类似你问题的问题。
他们都测量了1 mW参考值的相同值:0.00 dBm。这是一款全新的N8481A吗?
您是否一直对此传感器有这个问题,或者这是一个新问题?
您正在读取的确切信息;当使用灰色电缆时,使用蓝色电缆时的正确电平下降30 dB,表明使用灰色电缆时功率传感器有问题。
我认为唯一可能导致这种情况的原因是,当使用灰色电缆时,功率计正在正确读取功率传感器的“感应”电阻。
但我无法想象为什么使用蓝色电缆时不会出现这个问题.N8481A的序列号是什么?
可能必须将此传感器发送回Agilent服务中心进行测试。

     以下为原文

  I tried your setup on my E4416A with firmware revision A1.05.00 and my N8481A with both the blue cable and the grey cable.  I had not problem similar to your problem.  They both measured the same value from the 1 mW reference: 0.00 dBm.

Is this a brand new N8481A?  Have you always had this problem with this sensor, or is this a new problem?  The fact that you are reading exact;u 30 dB down when using the grey cable and the proper level when using the blue cable indicates to me that there is something wrong with the power sensor when using the grey cable.  The only potential reason that I think would cause this is if the power meter is reading the power sensor's "sense" resistor incorrectly when using the grey cable.  But I can not imagine why this problem would not occur when using the blue cable.

What is the serial number for the N8481A?  This sensor may have to be sent back to the Agilent Service Center for testing.

序列号为MY48100513,全新。
我也认为问题出在传感器上,但在两个不同的E4418B米上使用灰色电缆可以正常工作。无论如何它现在都可以使用,我已经尝试了几条电缆并且它们都适用于它们,我会关注它一段时间。
谢谢你的帮助。

  The serial number is MY48100513, it is brand new. I too thought the problem was with the sensor but it works fine with gray cables on two different E4418B meters.

Anyway it works now, I have tried several cables and it works with them all, I will keep an eye on it for a while. Thanks for your help.
