没有忘记 - 抱歉延迟...

  Haven't forgotten - sorry for the delay...

嗨 - 我们没有任何电流信号发生器可以满足您的最小上升/下降时间1ns。
我们的PSG的典型上升/下降时间为6ns，而EXG / MXG-B的典型值为7ns。
如果你对上面提到的上升/下降时间没问题，那么N5172B可以满足其他特性。
如果您对其他规格有疑问，请在此处找到数据表：http：//www.home.agilent.com/agilent/redirector.jspx？action =obs＆amp; nid = -536906709.3.00＆amp ;lc = eng＆amp; cc =
US＆amp; ckey = 2163727＆amp; pubno = 5991-0039EN＆amp; ltype = LitStation＆amp; ctype = AGILENT_EDITORIAL我希望这有帮助 -

  Hi -

We do not have any current signal generators that will meet your minimum rise/fall times of 1ns.  

Our PSG has a typical rise/fall time of 6ns, and our EXG/MXG-B has a typical of 7ns.  

The other characteristics can be met with the N5172B, if you were okay with the mentioned rise/fall times.  

The data sheet can be found here if you have questions about other specifications:  http://www.home.agilent.com/agilent/redirector.jspx?action=obs&nid=-536906709.3.00&lc=eng&cc=US&ckey=2163727&pubno=5991-0039EN<ype=LitStation&ctype=AGILENT_EDITORIAL

I hope this helped -
