带有labview的安捷伦示波器改变了触发值

信号是什么？
DC？
信号必须经过一些最小屏幕高度才能触发：触发灵敏度：



     以下为原文

  What is the signal? DC?

The signal MUST go through some minimum screen height to trigger:
Trigger sensitivity: < 10 mV/div: greater of 1 div or 5 mV; ≥ 10 mV/div: 0.6 div

The ONLY way to trigger on DC is ion AUTO trigger mode, not NORMAL.

You can also use the :TRIGger:FORCe command if it's DC.

谢谢你，但我的信号是sinuzoidale，当我将输入通道幅度从高电压变为低电压（从1伏到30毫伏）而不改变垂直范围到0.019伏时，我的示波器（agilent dso 7012B）的接口被阻挡。
（所以我不得不将垂直范围设置为0.019以正确运行界面）。
当我的界面被阻止时，通知“trigd？”的图标
在示波器的屏幕​​上闪烁。
我试图将触发边缘的水平改为低值（0.1,0.001,0），但他的问题是一样的。
但是当我将输入通道幅度从低电压更改为高电压时，程序运行正常并且他没有阻塞。
谢谢



     以下为原文

  thank you but my signal is sinuzoidale 
and the interface of my oscilloscope(agilent dso 7012B) is blocked, when i change the input channel amplitude from high voltage to low voltag (from 1 v to 30mv ) without changing the vertical range to 0.019 v .(so i'am obliged to set the vertical range to 0.019 to run correctly the interface ).

notify that when my interface is blocked the icon of "trigd?" flashes in the screen of  the scope .

i'am tried to change the level of trigger edge to low value (0.1,0.001,0) but he problem is the same .

but when i change the input channel amplitude from low voltage to high voltage the program run correctly and he didn't block  .

thank you

在了解范围和信号之前，请停止使用LabView。
点击“AutoScale”会发生什么？
你信号的幅度是多少？
范围设置为什么？
绝不应将示波器刻度设置为小于幅度的1/8左右。
您不希望信号离开屏幕。
这只会使放大器饱和，最终可能导致它们失效。
我不明白为什么要将示波器的垂直刻度从1V改为30 mV。
免责声明：为了获得更可靠的响应，您应该考虑致电当地的安捷伦技术呼叫中心。
安捷伦论坛在“可用”的基础上进行监控，并不一定是解决技术问题的最快方式。



     以下为原文

  Stop using LabView until you understand the scope and your signal.

What happens when you hit "AutoScale"? What is the amplitude of your signal? What does the scope get set to?

You should NEVER set the scope scale to be less than about 1/8 of the amplitude. You don't want the signal to go off-screen. That just saturates the amplifiers, and may eventually cause them to fail.

I don't understand why you are changing the vertical scale of the scope from 1V to 30 mV.

谢谢你的anser信号在范围内是正确的而不使用labview，并且当我设置自动缩放时，从labview中发生任何不发生的事情（可能是因为在我设置低电压（30mv）时，可能会继续设置），在屏幕上
sinuzoidale波形的范围变得像一个常数（不在我的表面，并且labview被阻止，



     以下为原文

  thank you for your anser 
the signal is correct in the scope without using labview ,and from the labview when i set autoscale anything  not happen  (may be because the vetical range is set continuesly)

when i set low voltage(30mv) ,in the screen of the scope the sinuzoidale  waveform become like  a constant (not in my inerface and the labview is blocked ,
