如何使用网络分析仪对功率放大器进行类似的IMD测量

嗨,我已经阅读了应用笔记“使用ENA的创新无源互调(PIM)和S参数测量解决方案”(5991-0332EN),其中显示了双工器互调测量的示例。
我还看到了使用网络分析仪对功率放大器进行类似的IMD测量。
我的问题是(1)这是否可以用于无源滤波器IP3测量?
(我的印象是肯定的,因为网络分析仪接收器用于测量两个音调主信号,以及两个IMD信号,接收器在四个频段上运行)。
(2)一点测量需要多长时间?
从频谱分析仪板,我得到了Dr_joel的建议,最新的PNA-X可以轻松测量和扫除IIP3与功率,频率或音调间距,测量速度可达每秒200点或更快。
但是,对于PNA-X型号,我的预算还不够。
(3)如果我希望每个点实现1秒的测量(对于大批量测试),您对Aglient网络分析仪模型有什么建议吗?
(由于预算有限,便宜的便宜。)非常感谢!

  Hi, all

I have read about the application note "Innovative passive intermodulation (PIM) and S-parameter measurement solution with the ENA" (5991-0332EN), in which the example of duplexer intermodulation measurement is shown.  
I have also seen similar IMD measurements of power amplifiers with network analyzer.

My questions are
(1) Whether this can be used for the passive filter IP3 measurement? (My impression is yes, as the network analyzer receiver is used for the measuring of both two tone main signals, as well as two IMD signals, the receiver operating on four bands).  

(2) How long would it take for one point measurement? From spectrum analyzer board, I got the advice from Dr_joel, the latest PNA-X could easily measure and sweep out IIP3 vs Power, Frequency or Tone spacing, with measurement speeds upwards of 200 points a second or faster. However, my budget is not enough for the PNA-X model.  

(3) If I would like to have the measurement realizing 1sec per point (for high-volume test), do you have any recommendations on the Aglient network analyzer models? (cheap ones are preferred, as the budget is limited.)

Thank you very much!

Yours,
Yiliu

亲爱的Yiliu感谢您的垂询。
(1)这是否可用于无源滤波器IP3测量?
(我的印象是肯定的,因为网络分析仪接收器用于测量两个音调主信号,以及两个IMD信号,接收器在四个频段上运行)。
尽管它取决于DUT类型(例如:BTS fitler或手机滤波器),但可以使用E5072A测量无源滤波器IP3。
(2)一点测量需要多长时间?
从频谱分析仪板,我得到了Dr_joel的建议,最新的PNA-X可以轻松测量和扫除IIP3与功率,频率或音调间距,测量速度可达每秒200点或更快。
但是,对于PNA-X型号,我的预算还不够。
在一般情况下,测量速度取决于IF带宽(IFBW)设置。
如果IFBW为10Hz,则测量速度为每秒几个点。
(3)如果我希望每个点实现1秒的测量(对于大批量测试),您对Aglient网络分析仪模型有什么建议吗?
(廉价的是首选,因为预算有限。)正如我上面所写,E5072A将是一个很好的解决方案,但它取决于DUT类型和测量要求。
如果您在此论坛上分享详细信息或与我联系(takehi_okabe@agilent.com),我将不胜感激。

  Dear Yiliu

Thank you for your inquiry.

(1) Whether this can be used for the passive filter IP3 measurement? (My impression is yes, as the network analyzer receiver is used for the measuring of both two tone main signals, as well as two IMD signals, the receiver operating on four bands). 

Altough it depends on DUT type (for example: BTS fitler or Handset filter), It would be possible to measure the passive filter IP3 using E5072A.

(2) How long would it take for one point measurement? From spectrum analyzer board, I got the advice from Dr_joel, the latest PNA-X could easily measure and sweep out IIP3 vs Power, Frequency or Tone spacing, with measurement speeds upwards of 200 points a second or faster. However, my budget is not enough for the PNA-X model. 

In geneal, measurement speed depends on IF bandwidth(IFBW) setting. If IFBW is 10Hz, measurement speeds is a few points per second.

(3) If I would like to have the measurement realizing 1sec per point (for high-volume test), do you have any recommendations on the Aglient network analyzer models? (cheap ones are preferred, as the budget is limited.)

As I wrote above, E5072A would be good solution, but it depends on DUT type and measurement requirement.
I would appreciate if you share detailed inforation on this forum, or contact me (takeshi_okabe@agilent.com).
