声子，离子晶体的横光学声子与光子相互作用产生的极化激元，金属的等离子体振荡，金属和半导体的回旋共振等。 我们对光学晶体MgF2单晶在THz频范围的波谱进行了实验研究．在0.5—2.5THz范围测出MgF2单晶的THz波吸收谱和折射率谱。

对于我们的项目，我们使用CurPress芯片43362的村田SN80UFL模块。我们的仪器运往世界各地，因此我们必须在许多国家进行一些法规测试。为此，我们使用加载到芯片的43362A2-MFGTest.Bin文件和WL工具，我们可以与芯片进行通信。原则上，与模块的通信工作是因为我们获得了“CurueEthAdDR”命令的正确值，并且传输模式也在正常工作。但是接收模式似乎不起作用。我们使用下面的脚本来激活模式：\\WLLoo\\WL43362A2.EX-串行27向下\\WLLoo\\WL43362A2.EX-串行27 MPC 0\\WLLoo\\WL43362A2.EX-串行27国家所有\\WLLoo\\WL43362A2.EX-串行27扫描抑制1\\WLLoo\\WL43362A2.EX-串行27通道1\\WLLoo\\WL43362A2.EX-串行27 BI 65535\\WLLoo\\WL43362A2.EX-串行27向上但我们总能看到有一个永久的可见峰。附上你可以找到测量。峰值的频率也根据配置的信道号而改变。因此，韩国测试失败，因为我们总是超过-57 dBm的限制。通常在接收模式下不应该有可见的峰值。我们已经与村田接触了几个星期，但不幸的是没有成功。他们建议在塞浦路斯论坛上发布这个问题，因为这与芯片本身有关。你能支持我们吗？你知道什么是错的吗？接收量20180619.PNG19.3 K 以上来自于百度翻译 以下为原文For our projects we use the Murata SN8000UFL module with the Cypress chip 43362. Our instruments are shipped world-wide therefore we have to perform in many countries some regulation tests. For this we use the 43362a2-mfgtest.bin file that is loaded to the chip and by the WL tool we can communicate with the chip. In principal the communication with the module works due we get for commands like "cur_etheraddr" the correct values and also the transmit mode is working correctly. But the receive mode seems not to work. We use following script to enbale the mode:..\\wl_tool\\wl43362A2.exe --serial 27 down..\\wl_tool\\wl43362A2.exe --serial 27 mpc 0..\\wl_tool\\wl43362A2.exe --serial 27 country ALL..\\wl_tool\\wl43362A2.exe --serial 27 scansuppress 1..\\wl_tool\\wl43362A2.exe --serial 27 channel 1..\\wl_tool\\wl43362A2.exe --serial 27 bi 65535..\\wl_tool\\wl43362A2.exe --serial 27 up But we always can see that there is a permanent peak visible. Attached you can find the measurement. The frequency of the peak is changing also depending on the channel number that is configured.Therefore the Korea tests fail due the we always exceed the limits of -57dBm. Normally in the receive mode there should be no peak visible. We are already in contact with Murata since several weeks but unfortunately with no success. They have proposed to post this issue in the cypress forum because this is related to the chip itself.Could you please support us? Do you have any idea what is wrong? Receive_Peak20180619.PNG 19.3 K
