嗨，我希望在以下问题上提供一些帮助：我通过远程labview界面在DUT上进行CW时间测量...例如CW频率= 20Ghz，IF BW = 700Hz，扫描时间20秒，步进模式，单触发我注意到的是，当我触发测量时，数据采集20秒，然后在接下来的20秒内“显示”或处理数据。这意味着为了让我真正得到测试结果，需要大约40秒。有没有办法在指定的20秒内获取数据，并立即保存文件并继续下一次测量？谢谢。 以上来自于谷歌翻译 以下为原文Hi, I'm hoping for some help on the following issue: I am making CW-Time measurements on a DUT through a remote labview interface... example would be CW Frequency = 20Ghz, IF BW = 700Hz, Sweep time 20seconds, Stepped mode, single-trigger What I am noticing is that when I trigger the measurement, the data is taken for 20 seconds, and then for the next 20 seconds data is "displayed" or processed.This means that in order for me to actually get the result of the test, it takes ~40 seconds.Is there a way to acquire data during the specified 20 seconds, and immediately save the file and move on to the next measurement? Thanks.

IM工作在一个与ADC有关的问题上，并且发现处理器文件（PIC32 MZ2048 EFM）丢失了5的寄存器。ADCTRG4到8…这些寄存器似乎在Selink中存在，但它们没有在TEH代码中定义。我可以再添加一些定义吗？ 以上来自于百度翻译 以下为原文 Im workign on a problem related to an ADC, and have found that the processor files (PIC32MZ2048EFM) are missing 5 of the registers..ADCTRG4 through 8..It seems that these registers do exisit in silcone, but they have not been defined in teh code. Can i just add some more definitions.

大家好，我一直很好奇这个问题。我以前只用一个.c文件编程，我不知道编译器和链接器是如何在多个.c文件的情况下工作的。如果我有多个.c文件，它们的命令是什么链接和编译的？包括：“p18f*LCD.h”int main（空隙）{……；返回；0 }} PIC18FYLCDCDAPAP1.1.C包含l&；XC.H.＆G.；例如：nNealSchar）{实现；} ***********.p18fyLCD.HOLL OpenLCD（无效）；无效写CFDCMLCD（unChar Car）；*************xc.h包括HTC.H，HTC.H包括CCI.H，XC8Debug .h，CCI。H包括γ.H.My猜想是：1。预处理器指令IPC18FYLCDAppApp1.1.C2的预处理器。将PIC18FYLCDCDAPAP1.1.C编译成目标文件，在此过程中链接器将帮助查找头文件3的实现。PIC18FYLCDCDAPAP1.1.O输出了4。在Lab.C5中处理预处理器指令的预处理器。编译Lab1.c，在此过程中链接器将帮助查找头文件6的实现。O到了7岁。将两个.0文件合并成一个.O文件（不确定）8。将文件转换成.HEX文件（不确定），请给我一个让我知道它的手。 以上来自于百度翻译 以下为原文 Hello, everyone, I've been being curious about this question in detail.I only programmed with one .c file before, I don't know how compiler and linker work in multiple .c file situation. if I got multiple .c file, what is their order being linked and compiled? for example:***********************Lab1.c#include #include "P18F_LCD.h"int main(void){......................;return 0;}***********************PIC18F_LCD_APP001.c#include#include #include "P18F_LCD.h"void OpenLCD (void) { implementation;}void WriteCmdLCD ( unsigned char ) { implementation;}***********************P18F_LCD.hvoid OpenLCD (void) ;void WriteCmdLCD ( unsigned char ) ;***********************xc.h includes htc.h, htc.h includes cci.h, xc8debug.h,cci.h includes __at.h My guess is:1. Preprocessor dealing with preprocessor directive in PIC18F_LCD_APP001.c2. PIC18F_LCD_APP001.c be compiled into object file, during this procedure linker will help finding implementation of header files3. PIC18F_LCD_APP001.o came out4. Preprocessor dealing with preprocessor directive in Lab.c5. compile Lab1.c, during this procedure linker will help finding implementation of header files6. Lab1.o came out7. combined two .o file into one .o file (not sure)8. convert .o file into .hex file (not sure) Please please give me a hand to get me knowing it, 小弟感激萬分!

嗨，我有一个奇怪的问题时，从V1.33编译器（我有一个完整的许可证，但ASPIC18问题）到V1.45。我有发送和接收缓冲器定义的UART2（PIC18F45 K80）。根据定义的大小，Rx2缓冲区或Tx2缓冲区在地址0x60内存中启动。当运行程序时，第一个字节（0x60）总是在从ISR返回之后被重写为0（如我所见）。我做了很多测试，发现我可以通过引入一些哑变量来阻止这个。我不知道变量“BTEMP”是从哪里来的，我在任何地方都没有它。但这取决于“BTEP”和0x60的缓冲区之间有多少字节。如果它是三字节，代码工作。如果只有一个或两个字节，0x60被覆盖。有人有线索吗？Br，Jo.Rg。 以上来自于百度翻译 以下为原文 Hi,I have a strange problem when moving from V1.33 compiler (where I have a full license but aspic18 problems) to V1.45.I have transmit and receive buffers defined for the UART2 (PIC18F45K80). Depending on the sizes defined, either Rx2Buffer or Tx2Buffer starts in memory at address 0x60. When running the program, always the first byte (at 0x60) is overwritten with 0 after returning from the ISR (as far as I can see). I made a lot of tests and found that I can stop this by introducing some dummy variables. I have no idea where variable 'btemp' comes from, I do not have it in the sources anywhere. But it depends on how many bytes lie between 'btemp' and the buffer start at 0x60. If its is three bytes, the code works. If it is only one or two bytes, 0x60 is overwritten.Does anybody have a clue?

这是关于理解VNA规范的一般问题。我拥有8753C（但我必须使用其他网络分析仪完成我的工作），我必须与客户和管理层就网络分析仪测量的准确性进行对应。因此，我的回复必须准确并且不能“一般”正确，因为这些测量可能与校准实验室测试或具有严格标准的一些其他应用相关联。如果我看一下“相位特性” - 频率响应偏离线性部分的接收机仪器规格，则从300KHz到3 GHz有一个规格+或负3度。根据这个规范。我看到了一个图表。我需要解释这个图表关于可以在实际相角测量中正式断言的内容。从图中可以看出，6 GHz时线性偏离2度（参见用户手册第19-873C仪器规格部分），3 GHz时偏差约1度。假设我运行了性能测试，我的性能测试数据输出与图表完全相同。我是否可以告诉想要了解相位测量精度的客户，我的相位测量值在6 GHz±2度和3 GHz一度（测试数据）？或者我只能说安捷伦在正负3度指定其NA相位测量值（也就是说，如果“线性相位特性”的这种解释等于相位测量的相位角“精度”测量值）。术语“线性相位特性”是否等于相位角“精度”测量值？请帮我准确定义这些规范的真正含义。感谢您过去的回复。编辑：SOLT_guy于2012年5月21日上午4:11编辑：SOLT_guy于2012年5月21日上午4:13编辑：SOLT_guy于2012年5月21日下午3:54编辑：SOLT_guy于2012年5月21日3： 57 PME编辑：SOLT_guy于2012年5月30日上午1:07 以上来自于谷歌翻译 以下为原文This is a general question about understanding VNA specs. I own a 8753C (but I have to use other network analyzers for my job) and I have to correspond with customers and management with respect to the accuracy of the network analyzer measurements. Therefore, my replies have to be exact and cannot be "generally" correct because these measurements may be associated with calibration laboratory tests or some other application with exacting standards. If I look at the receiver instrument specifications under the section, "Phase Characteristics" - Frequency Response Deviation from Linear, there is a spec + or minus 3 degrees from 300KHz to 3 GHz.Under this spec.I see a graph. I need to interpret this graph with regard to what can be formally asserted with respect to actual phase angle measurements. From the graph I can see that there is a 2 degree deviation from linear at 6 GHz (see page 19 - 8753Cinstrument specifications section of the user manual) and about one degree deviation at 3 GHz. Let's say I ran a performance test and my performance test data output was exactly the same as the graph. Can I tell a customer who wants to know the accuracy of my phase measurements that my phase measurement is within plus or minus 2 degrees at 6 GHz and one degree at 3 GHz (data from a test)? Or am I only entitled to say that Agilent specifies its NA phase measurements at plus or minus 3 degrees (that is, if this interpretation of "linear phase characteristics" is equivalent to the phase angle "accuracy" measure of a phase measurement). Is the term "linear phase characteristics" equivalent to the phase angle "accuracy" measure? Please help me define exactly what these specifications are really saying. Thank you for your past replies.
