Hello,my instrument is blocked when i make a low voltage,so i think to the trigger edge but he probleme is not solved by the trigger edge and the scope is blocked and the trigger icon will flashes in the screen of the oscilloscope

i was chhanged the value of trigger level for many value(0,0.00001,1,.........) but the problem is the same ,can some help me :)

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.

  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

    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.

      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 ,
