多载波测量PXA信号分析仪怎么使用

Hi Leyo - 请参阅* bold *中的内容 - 我正在尝试使用PXA信号分析仪测量多载波基站发射机的ACP。
载波间隔为1MHz，有6个载波具有GMSk调制。
每个载波的功率为36.4 dBm。
*我希望你有足够的外部衰减，因为PXA的安全输入电平为+30 dBm，你插入+36 dBm !! *在载波配置的ACP设置中，有一个叫做“Measurement Noise BW”的按钮
。
这个BW有什么意义？
这是测量电枢功率的BW吗？
*按下：配置运营商按钮后，按绿色帮助键，然后按测量噪声带宽键。
您现在将看到密钥的描述。
实际上，这是测量载波功率的BW。*我的载波BW是200KHz（GMSK）。
但是将测量噪声BW分成200KHz，每个载波的测量功率比预期的36.4dBm小约1.5dB。
为了获得36.4 dBm的载波功率，测量带宽应该在1MHz左右？
*是的，36.4 dBm载波功率是所有6个载波的总载波功率。
每个单独的载波功率较小，并且6个载波“相加”以提供预期的36.4dBm的总载波功率。*这也与“Integ BW”和“RRC加权”的测量方法相关联。
请解释这些方法之间的区别。
*上面使用的帮助功能无法回答此问题。

  Hi Leyo -

See coments in *bold* -

I am trying to measure the ACP of a multi-carrier basestation transmitter using PXA signal anlyzer. 
The carriers are spaced @ 1MHz and there are 6 carriers with GMSk modulation. Power of each carrier is 36.4 dBm. *I hope you have ample external attenuation applied since the safe input level to the PXA is  +30 dBm, and you are inserting +36 dBm!!*
In the ACP setup for carrier configurations, there is a a button called "Measurement Noise BW". What is the siginificance of this BW. Is this the BW in which the acrrier power is measured?. 
*After you press: Configure Carriers button, press the green Help key, then press Measurement Noise Bandwidth key. You will now see the description of the key. Indeed this is the BW which the carrier power is measured.*
My carriers BW is 200 KHz(GMSK) . But seeting the measurement noise BW to 200 KHz, the measured power of each carriers is around 1.5 dB less than the expected 36.4 dBm. To get carrier power of 36.4 dBm, the measurement BW should be around 1MHz? *Yes, the 36.4 dBm carrier power is the total carrier power of all 6 carriers. Each individual carrier power is less, and the 6 carriers “add” to provide the expected 36.4 dBm total carrier power.*

Also is this tied to the measurment method of "Integ BW" and "RRC weighted". Please explain the difference between these methods. 
*The Help feature used above does not answer this question. While on the subject of where to find more information, please see the PXA User’s and Programmers Reference at:*

您好，感谢您的回复。
是的，我在PXA前面有40 dB的衰减。
因此，PXA信号水平得到了解决。
36.4 dBm是每个载波的功率。
我期望总功率为36.4 dBm + 10 * log（10）。
当测量噪声BW为200KHz时，每个载波功率比预期的低1.5dB。
如果测量噪声BW与积分BW相同，为什么它不被命名为积分BW。
对于偏移测量的情况，将其命名为积分BW。
对于载波功率测量，我们必须在积分BW和RBW之间保持任何比例吗？
谢谢，Leyo

  Hello, 

Thank for the response. 
Yes, I have 40 dB of  attenuation in-front of PXA. So PXA signal level is taken care of. 
The 36.4 dBm is the power of each carrier. I am expecting  total power of 36.4 dBm+10*log(10). Each individual carrier power is 1.5 dB less than expected when the measurement noise BW is 200 KHz. 
If the measurement noise BW is same as integration BW, why it is not named as integration BW. For the case of offset measurements, it is named as integration BW. 
For carrier power measurement,  is there any ratio we have to maintain between integration BW and RBW?. 
Thanks, 
Leyo
