*inContext = dlg->InEndpt->BeginDataXfer(inData,inlen,&inOvLap);的返回值为空，inData也为空，不知道把接收的值放哪了，请问是什么原因呢？ 谢谢各位

我需要用Labview调用一个名为DTKDownloadA 的函数，函数的定义如下 UINTWINAPI DTKDownloadA(UINT uDeviceID, LPWSTR lpwDownload, BOOL bDowoload, PDOWNLOAD_PROGRESS lpDownloadProgress, PDOWNLOAD_MESSAGE_A lpwDownloadMessage);前面三个参数都比较明确，后面两个参数是属于下面两个自定义格式typedef VOID (WINAPI *PDOWNLOAD_PROGRESS)(INT nPercent);typedef VOID (WINAPI *PDOWNLOAD_MESSAGE_A)(LPSTR lpMessage);这两个参数给我的感觉好像就是api函数，请问这种参数该如何在LabView调用库函数里定义呢？（将其考虑为int32和char的我的试过了，走不通）

大家好，使用Simulink驱动程序，我能够[从远端/远端站点接收生成LTE数据包的数据包]。下面是我的设置LTE发生器[下变频RF数据包] - >转换为以太网数据包---> Simulink - >安捷伦[[89601B-BHE或89601B-BHD]] VSA软件[仅软件无硬件]请注意一代[LTE发生器]正在数英里外发生，它以以太网数据包格式传输并送入simulink，然后送入Agilent VSA驱动程序。由于VSA不是基于触发运行[请注意它是在自由运行的基础上运行]，是否可以通过LTE解码LTE矢量[89601B-BHE或89601B-BHD] [基于标准的信号评估和故障排除工具]谢谢Madeline编辑：Madeline于2013年3月11日下午12:39 以上来自于谷歌翻译 以下为原文Hi All, Using Simulink drivers, i am able to receive a packet [from a far/distant site, where LTE packets are being generated].

13.x of 89600不再支持将E4440A用作下变频器。对我来说很糟糕，因为我正在使用它来支持更高频率到我的旧的基于VXI的VSA。有没有重新启用它的黑客，类似于修改Windows注册表让12.x识别E4406A？ 以上来自于谷歌翻译 以下为原文13.x of 89600 no longer supports using the E4440A as a downconverter.Stinks for me since that's how I'm using it to support higher frequencies into my older VXI based VSA.Is there a hack to re-enable this, similar to modifying the windows registry to let 12.x to recognize the E4406A?

嗨，我正在使用EXA和VSA软件在5210MHz的WLAN 802.11b模块上进行一些测量。 （附截图）我在下面有一些问题。 1）在连续模式传输中，EVM约为35％。 a）在VXA模式下，当使用滤波器长度= 22且收敛= 0.01时自适应均衡器开启时，EVM降低至小于3％。 b）在VSA模式下，当自适应均衡器打开时，它似乎没有收敛到相同的设置。 2）在突发模式传输中，使用IF触发，观察到类似的问题，但是，似乎可以通过改变RRC alpha因子和符号时序而不使用自适应均衡器来改进EVM测量，并且最佳evm大约为8当使用RRC因子为0.25且符号定时为0.22时的％。 3）使用自适应均衡器的推荐设置是什么？它应该在生产测试期间打开吗？关于此的任何应用笔记？ 4）测试的模块不实现RRC滤波器类型，而是5阶逆chebyshev低通滤波器。那么推荐使用的通道过滤器设置应该是什么？ 5）通过设置符号时序，它会对生产测试产生影响吗？希望你能帮忙。 DWHP83_ConTx_5210MHz_VSA_RRC035_EqOn1.jpg232.5 KBDWHP83_ConTx_5210MHz_VXA_RRC035_EqOn.png79.0 KB 以上来自于谷歌翻译 以下为原文Hi, I'm using EXA with VSA software to do some measurements with my WLAN 802.11b module at 5210MHz. (attached screenshots) I have some questions below. 1)In continuous mode transmission, the EVM is about 35%. a)In VXA mode, when the adaptive equalizer is on using Filter Length=22 and convergence=0.01, the EVM reduced to less than 3%. b)In VSA mode, when the adaptive equalizer is on, it doesn’t seems to converge with the same settings. 2)In burst mode transmission, using IF trigger, similar issue was observed as before, however, it seems that the EVM measurements can be improved without using adaptive equalizer by changing the RRC alpha factor and symbol timing, and the optimum evm is about 8% when using RRC factor at 0.25 and symbol timing at 0.22. 3)What should be the recommended setting for using the adaptive equalizer? Should it be turned on during production testing? Any app notes on this? 4)The module tested do not implement a RRC filter type, instead it is a 5th order inverse chebyshev low pass filter. What should be the recommended channel filter setting used then? 5)By setting the symbol timing, will it have any impact on the production testing? Hope you can help.附件DWHP83_ConTx_5210MHz_VSA_RRC035_EqOff.jpg232.5 KBDWHP83_ConTx_5210MHz_VSA_RRC035_EqOn1.jpg232.5 KBDWHP83_ConTx_5210MHz_VXA_RRC035_EqOn.png79.0 KB
