E4438C和信号工作室的TCPIP连接错误该怎么办？

我使用Signal Studio进行脉冲构建，使用TCPIP连接使用E4438C。
我调用了使用COM API在NI LabWindows / CVI中创建的AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern（ActiveX控制器）。这很好用，直到我从AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern函数中收到以下错误消息：无法从传输连接读取数据：连接
尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机无法响应。我的自动测试脚本循环基本上看起来像：LoopAgtPBAPI_IAgtPBProjectDownloadAndPlayPattern（来自先前创建的.pbp中的模式）
测量.End LoopI意识到问题可能有很多来源，包括测试PC（运行Windows 7），corportate局域网，网络交换等。我只是想知道是否有与E4438C的TCPIP连接问题的历史。

  I am using Signal Studio for Pulse Building and an E4438C using the TCPIP connection. I make calls to AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern (ActiveX Controller) which was created from within NI LabWindows/CVI with the COM API.
This works great, until I get the following error message from the AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern function:
Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

My automated test script loop basically looks like:

Loop
AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern (pattern from within a previously created .pbp)
Take a measurement.
End Loop

I realize the problem could have many sources including the test PC (running Windows 7), the corportate LAN, networking switching, etc.  I was just wondering if there is a history of TCPIP connection problems with the E4438C.
