如何通过LAN将数据从VNA e5071c传输到PC以测量S参数

您好，虽然我不是ENA的专家，但我想知道您的特定ENA上是否已经启用了网络I / O.
要进行检查，请转至系统>其他设置>网络设置，并确保将启用设置为开，如此处的ENA在线帮助中所述。



     以下为原文

  Hello, although I'm not an expert on the ENA, I'm wondering if the network I/O might not already be enabled on your particular ENA.  To check, go to System > Misc Setup > Network Setup, and ensure Enable is set to ON, as described in the ENA online help here.

亲爱的Utkarsh，正如bhokkan评论的那样，似乎缺少ENA网络设置。
还请运行Keysight Connectio Expert并检查您的E5071C是否配置正确。
如果配置了E5071C，VEE上的仪器管理器（菜单I / O - >仪器管理器）也将显示E5071C。



     以下为原文

  Dear Utkarsh,

As bhokkan commented, it seems to be of missing ENA networks setting.
Please also run  Keysight Connectio Expert and check if your E5071C is configured correctly.
If the E5071C is configured, Instrument manager on VEE (Menu I/O -> Instrument manager) will show the E5071C as well.

好。
现在我还设置了VNA网络设置并打开了SICL-LAN服务器。
但后来我也遇到了同样的问题。
或建议另一种方式。
是否需要VNA E5071c和外部Pc都应具有相同的IO库套件和操作系统。



     以下为原文

  ok. Now I also set VNA Network Setting and Turn ON the SICL-LAN server. But then also I am getting same problem. or suggest another way. is there any need that both VNA E5071c and External Pc should have same IO libraries suite and Operating system.

亲爱的Utkarsh，您是否在Keysight I / O库中成功地看到了“测试连接”和“识别仪器”的结果？
如果您这样做，请检查Keysight VEE计划中的VISA地址是否正确。
如果不这样做，仪器的网络设置可能是错误的。
另请检查局域网设置。



     以下为原文

  Dear Utkarsh,

Do you see results of  "Test Connection" and "Identify Instrument" successfully in Keysight I/O Library as described in the webhelp?

If you do, please check if VISA address is correnct in Keysight VEE program.
If you don't, network setting of the instrument may be wrong. Please also check  LAN setting.

  Dear Utkarsh,

There are a few types of command to get measurement data.

:CALCulate{1]-160}[:SELected]:DATA:FDATa? ( [webhelp)
  This command sets/gets the formatted data array, for the active trace of selected channel.

Sample code to get ch1, trace1 data array:
:CALC1:PAR1:SEL
:CALC1:DATA:FDAT?
read fdata in real format array 1D (array size depends on NOP)


:CALCulate{1]-160}[:SELected]:DATA:SDATa? ( [webhelp)
  This command sets/gets the corrected data array, for the active trace of selected channel.

Sample code to get ch1, trace1 data array:
:CALC1:PAR1:SEL
:CALC1:DATA:SDAT?
read sdata in comlex format array 1D (array size depends on NOP)

谢谢Mr.takeshio但是我想读取跟踪数量的数据。
实际上，当手动我要保存跟踪时，它只保存该瞬间的跟踪。
因为我不断传输信号，我不想要。
痕迹进一步分析。
那我应该怎么做呢。
请给出建议。



     以下为原文

  Thanks Mr.takeshio 
But i want to read the data for No. of traces. actually when manually i am going to save trace, it save trace only for that instant. since i am continuously transmitting the signal, I want no. of traces for further analysis. so what should i do for that. 
Please give the suggestion.

我不确定ENA的命令，也没有访问权限。
您需要在连接仪器的情况下逐步执行MATLAB代码，看看是否有任何错误产生错误。
或者，浏览ENA的SCPI程序员手册并找到正确的命令集。



     以下为原文

  I'm not sure of the commands for the ENA and don't have access to one. You will need to step through the MATLAB code with your instrument connected and see if any of those produce an error. 

Alternatively, go through the SCPI programmers manual for the ENA and find the right set of commands.

亲爱的Utkarsh，我不熟悉Matlab编程，但这是我对ENA SCPI命令的评论。

它看起来像PNA的SCPI命令，这个保存touchstone文件的命令不支持ENA的binblock格式。



     以下为原文

  Dear Utkarsh ,

I am not familiar with Matlab programming, but here are my comment regarding ENA SCPI commands.

> % Set instrument to return the data back using binblock format
> fprintf(obj1, 'FORMat REAL,64');
> % Set byte order to swapped (little-endian) format. SWAPped is required

When you use binblock format, limited SCPI command can be used as below webhelp shows,

http://ctdkobe-lp.png.is.keysight.com/webhelp/ena/programming/command_reference/format/scpi_format_data.htm

> % Request 2-port measurement data from instrument
> fprintf(obj1, 'CALC:DATA:SNP:PORTs? ''1,2''');

It looks PNA's SCPI command and this command to save touchstone file does not support binblock format for the ENA.

> {quote：title = Utkarsh写道：} {quote}>％从仪器请求2端口测量数据> fprintf（obj1，'CALC：DATA：SNP：PORTs？''1,2'''）;
>我认为这只会返回alpha，而不是二进制。
您可以以二进制形式获取单个跟踪数据，但不能获取完整的SnP数据。

  > {quote:title=Utkarsh wrote:}{quote}

I think this only returns alpha, not binary.  You can get individual trace data in binary form, but not full SnP data.

哪个命令应该用于从VNA到PC的SnP数据传输。
是校正数据和SnP（试金石文件）是一样的吗？
我想将校正数据（Real-Imaginary格式）从VNA e5071c（ENA系列）传输到matlab工作空间。
请帮忙。



     以下为原文

  which command should be used for SnP data transfer from VNA to PC. is the corrected data and SnP (touchstone file) are same? 
I want to transfer corrected data (Real-Imaginary format) from VNA e5071c (ENA series) to matlab workspace. Please help.

从ENA的vee程序示例：Calc：Par：Sel 1 // for trace 1 Calc：data：sdata？
然后读取1个字符的标题。
然后读取一个字符，该字符是下一个条目的大小“x”（通常为3或4），在本例中为4然后读取'x'字符，这是下一个条目的大小（例如1601）然后读取下一个1601
表示数据的字节。
这通常是真实的32位数和虚数的32位数。
或使用IEEE bin块进行读取。



     以下为原文

  From the vee program example for the ENA:

Calc:Par:Sel 1  //for trace 1
Calc:data:sdata?

Then Read a header which is 1 character.
Then read a character which is the size 'x' of the next entry (usually 3 or 4), in this example 4
Then read 'x' charaters which is the size of the next entry (for example 1601)
Then read the next 1601 bytes that represents the data.  This would normally be a 32 bit number for real and a 32 bit number for imaginary.

Or use IEEE bin block to read.

vee有一个很好的示例程序，用于快速和最佳地读取ENA：C： Program Files（x86） Agilent  VEE Pro 9.3  examples  InstrumentIO  InstrManagerIntegrated并查找ENA示例AgE50xxx-ENA1或2

  vee has an excellent example program for quickly and optimally reading the ENA:

谢谢Dr.Joel但是你建议的示例程序是用于GPIB接口，而我使用的是LAN接口。
实际上我想连续读取数据。
用于测量S参数的迹线。
可以将数据从Vee pro保存到matlab工作区吗？
请给出你的建议。



     以下为原文

  Thank you Dr.Joel
But the example program you suggest is for GPIB interface while i am using LAN interface.
Actually i want to read the data continuously for no. of traces to measure the S-parameter. 
Can save the data from Vee pro to matlab workspace? Please give your suggestion.
