嗨Garvin，可能影响到这一点的一件事是硬件设置USB到GBIB接口的2秒超时。据我所知，这只会减慢一些事情，如果没有超时，当没有超时发生它运行为
快速作为国家仪器USB到GPIB。我不确定这是否会影响惠普和/或安捷伦制造的所有USB到GPIB。我们通过安捷伦USB到GPIB发现了这一点，安捷伦支持证实了这一点。 我们还没有找到任何解决方法（这就是我们现在购买NI USB到GPIB的原因）。来自_____，来自：Garvin，Al [mailto：al.garvin@lmco.com]发送时间：2006年2月13日15:14T：VRFSubject ：[vrf]使用HP 82357 u***到GPIB接口的定时问题我在Vee 7.03下的笔记本电脑上运行程序，在HP 8753ES网络分析仪上进行S11测量。 我可以使用它的两个接口之一。 一个是National Instruments PCMCIA-GPIB卡，另一个是HP 82357 u***到GPIB接口。 我在任何时候都只有笔记本电脑中的一个接口。我使用设置为3秒的“On cycle”对象来控制测量。 使用NI卡进行测量并返回数据需要382 ms。 使用HP 32357接口进行测量并返回数据需要2.82秒。 相同的代码和相同的仪器和相同的驱动程序（AG875X）。 对于HP接口来说这需要很长时间来进行测量这是正常的吗？我最终想要将“On cycle”对象设置为1秒。 Â谢谢，Al Garvin Lockheed Martin 以上来自于谷歌翻译 以下为原文 Hi Garvin,            One thing that might be affecting this is the hardware set 2 second timeout on the USB to GBIB interface. As far as I'm aware this only slows things down if something times out, when no timeouts occur it runs as fast as the National instruments USB to GPIB. I'm not sure if this affects all USB to GPIB made by HP and or Agilent or only some. We discovered this with our Agilent USB to GPIB and it was confirmed by Agilent support. We haven't found any way around it (that's why we buy NI USB to GPIB now).  Ben  _____  From: Garvin, Al [mailto:al.garvin@lmco.com] Sent: 13 February 2006 15:14 To: VRF Subject: [vrf] Timing issue using HP 82357 u*** to GPIB interface I have a program running on a laptop under Vee 7.03 which makes an S11 measurement on an HP 8753ES network analyzer. I am able to use one of two interfaces with it. One is a National Instruments PCMCIA-GPIB card and the other is the HP 82357 u*** to GPIB interface. I only have one of the interfaces in the laptop at any one time. I am using an "On cycle" object set to 3 seconds to control the measurement. Using the NI card it takes 382 ms to make the measurement and return the data. Using the HP 32357 interface it take 2.82 seconds to make the measurement and return the data. Same code and same instrument and same driver (AG875X). Is this normal for the HP interface to take so long to make the measurement? I eventually want to set the "On cycle" object to 1 second.  Thanks, Al Garvin Lockheed Martin

Al，有一个可下载的工具来自Microsoft“UVCView.x86.exe”（也包含在最近发布的IO库 - “C：Program FilesAgilentIO LibrariesSuite inu***u***viewu***view.exe”中），它提供了有关USB端口的信息。
它表示“设备总线速度”，它可能不是USB端口的实际能力。 它还列出了“RootHubs”和每个RootHub下的端口。 以下是该信息的（部分）示例：... ConnectionStatus：DeviceConnectedCurrent配置值：0x01设备总线速度：LowDevice地址：0x01打开管道：1 ...我的承诺是RootHub的可用资源由它共享的端口共享 供应。 这可能意味着每个端口（如果设备已连接并处于活动状态）可以以降低/共享的速度执行。 高速设备的性能也可能受到通过相同RootHub._Vinod连接的慢速设备的影响---“Garvin，Al”写道：> Vinod，>我不确定我的USP端口速度是多少。 我该怎么说？ 连接到u***端口的唯一>其他东西是鼠标，我正在使用>版本> M.01.01.04的IO库。 我将从安捷伦下载最新版本的>库，看看是否有所不同。>谢谢，> Al >> -----原始消息----->来自：Vinod [mailto：papineni_vinod @ yahoo。 com]>发送时间：2006年2月13日，星期一，上午7:58> To：Garvin，Al; VRF>主题：Re：[vrf]使用HP 82357 u***到GPIB接口的时间问题> >> Al，>>> USB端口的速度是多少？ 是否还有其他USB设备>连接到笔记本电脑上的任何其他USB端口？ 您正在使用的IO库的版本是什么？ 我记得读过一篇关于使用更新版本的IO libs＆amp; 82357A。>> -Vinod >> ---“Garvin，Al”写道：>>>我在Vee 7.03下的笔记本电脑上运行程序，在HP 8753ES网络分析仪上进行>> S11 >>>测量。 我能够使用一个>两个接口。 一个是National Instruments PCMCIA-GPIB >> card >>>，另一个是HP 82357 u***到GPIB接口。 我一次只有笔记本电脑中的一个接口。>>我使用“On cycle”对象设置为3秒来控制>>测量。 使用NI卡进行>测量>>需要382 ms并返回数据。 使用>> HP 32357接口进行测量需要2.82秒，然后>>返回数据。 相同的代码和相同的仪器和相同的驱动程序>（AG875X）。>>>> HP接口的正常情况需要很长时间才能进行测量吗？ 我最终想要>>将“On cycle”对象设置为1秒。>>谢谢，>> Al Garvin >> Lockheed Martin> >>> __________________________________________________>你是雅虎吗？？>厌倦了垃圾邮件？ 雅虎 邮件有最好的垃圾邮件保护> http://mail.yahoo.com> __________________________________________________你雅虎！？厌倦了垃圾邮件？ 雅虎 Mail拥有围绕http://mail.yahoo.com提供的最佳垃圾邮件保护---要订阅，请发送电子邮件至“owner-vrf@it.lists.it.agilent.com”。要取消订阅，请发送空白电子邮件至“ leave-vrf@it.lists.it.agilent.com“。要发送邮件到这个邮件列表，请发送电子邮件至”vrf@agilent.com“。 如果您需要有关邮件列表的帮助，请发送邮件至“owner-vrf@it.lists.it.agilent.com”。在“www.oswegosw.com/vrf_archive/”上搜索“非官方vrf档案”。 以上来自于谷歌翻译 以下为原文 Al, There is a downloadable utiltiy from Microsoft "UVCView.x86.exe" (also included with recent release of IO Libraries - "C:Program FilesAgilentIO Libraries Suite inu***u***viewu***view.exe") which gives information on the USB ports.
