Dear All,
I am very new to Labview. I want to use Labview to
control oscilloscope(Lecroy 344). I asked Lecroy
company for Lecroy 344's driver
and was told Lecroy 334's driver is OK.
Now I am trying to read waveforms from 3 channels
simultaneously.My flow chart goes as follows:
3 vertical setup modules -> timebase setup module
-> trigger setup module->3 read waveform modules.
The problem is: when I input a same signal(from
signal generator) into three channels at the same
time, the data from the three waveform outputs are
different. Sometimes,it seems the start points(t0)
of these channels are different, but even if t0
are same, the data are defferent. I use the
storage fuction of the oscilloscope, and it shows
the data are exact
ly same.
I do not know why this happens:my program's
problem or driver's problem?
Any suggestions or examples would be greatly
appreciated!
Thanks in advance.
