是否有人使用34980A IO卡以及34980A开关和测量单元?

只是想知道是否有人使用34980A I / O卡以及34980A开关和测量单元?
我需要从主时钟创建一个延迟时钟和一些延迟脉冲。
我确实需要对这些延迟进行精确计时,我想知道是否有可能从卡中创建这些信号,由于操作系统的延迟,也可能无法进行多次写入,我也有4张这样的卡。
我有一台运行HPVEE的PC通过Eithernet连接到34980A。谢谢。

  Just wondering if anyone is familair with the 34980A I/O card as well as the 34980A switch and measurement unit?  I need to create a delayed clock and a few delayed pulses from a master clock.  I do need precise timing on these delays,
I am wondering if it is possible to create these signals from the card, also probably could not do it with multiple writes because of the delay from the operating system,  I also have 4 of these cards.  I have a PC running HPVEE connected to the 34980A via Eithernet.
Thanks.

我相信你可以使用34950A数字IO卡为34980A使用缓冲(内存)IO。
将有大约½时钟周期时序不确定性。
34950A是一张相当复杂的卡片,因此需要进行一些实验才能让它完全符合您的要求,但用户指南最终会让您到达目的地。
也许有人在那里有一个例子来启动他们可以分享?

  I believe you can do this with the 34950A Digital IO card for the 34980A using buffered (memory) IO.   There will be about ½ clock cycle timing uncertainty.   The 34950A is a rather complex card so it takes some experimentation to get it to do exactly what you want, but the User’s Guide should will eventually get you there. 

Maybe somebody out there has an example to jump start you they can share?

感谢您的回应,我使用频闪作为时钟的缓冲输出,仍需要进行进一步的测试,但看起来可能会有效。

  thanks for the response, i am using buffered output with the strobe as a clock, still need to do further testing but looks like it may work out.
