使用VEE Pro 9.31进行Binblock编码的问题

大家好，我是学位学生，我目前正在从事T＆amp; M项目，该项目涉及编写VEE程序以自动化测量过程。
我在使用Direct I / O与仪器通信时遇到问题。
我使用的是非安捷伦仪器，我使用的是Rigol DS1102E数字示波器。
问题：我尝试通过Direct I / O使用SCPI命令从仪器读取跟踪数据，只能使用Read Text x作为str来获取完整的返回数据。
当我尝试在Array1D中使用Read Binblock x作为二进制时，我将遇到超时问题或数据数据解码不完整或者每次按下模拟都没有找到数据并且结果不一致，我应该从返回的数据中得到600点。
当我使用Agilent Interactive I / O和I / O监视器来了解返回的数据时，读取过程是正确的，返回的数据是HEX并转换为ASCII。
返回的消息请参见附件IO Montor Result.png。
根据我对IO Monitor结果的理解，我知道返回的数据是在无符号Int8中，因此，我首先使用ToFile对象使用Read Text x作为str保存数据，并使用FromFile Object将Read Binblock x作为Binary读回数据
在Array 1 D中，返回的数据能够完全解码。
问题：为什么Direct BinBlock x作为直接I / O事务中的二进制Array1D无法完全解码返回的数据？
是否需要对缓冲区大小进行任何设置或者我缺少哪一步？
请指教。
谢谢你，Jeremy Tan

  Hi all, I am a degree student and I currently working on a T&M project which involved in writing VEE program to automate a measurement process. I face a problem on using Direct I/O to communicate with the instrument. I am using non Agilent Instrument, I am using Rigol DS1102E Digital Oscilloscope.  

Problem:
I try to Read the trace data from the instrument using the SCPI command via Direct I/O, the was only able to use Read Text x as str to get the full returned data. When I tried to use Read Binblock x as Binary in Array1D, I will have a timeout issue or data data decoded incomplete or no data found every single time I pressed simulate and the result was not consistent , I should get 600points from the returned data. When I use the Agilent Interactive I/O and the I/O monitor to understand the returned data, the reading process was correctly and the returned data is in HEX and converted into ASCII. The returned message see attachement IO Montor Result.png. From my understanding through the IO Monitor result, I know the returned data is in unsigned Int8, therefore, I first save the data by using Read Text x as str using ToFile object and read the data back using FromFile Object with Read Binblock x as Binary in Array 1 D and the returned data was able to completely decode.

Question:
Why the Read BinBlock x as Binary Array1D in the Direct I/O transaction cannot completely decode the returned data? Is it I need to do any setting on the buffer size or what step I am missing?  

Please advise.  
Thanks

Regards,
Jeremy Tan
