Norma 4000 Waveform measuring

[gmilek]

Hello,

I have Norma 4000 connected via rs232 and I want to get the waveform of measured voltage in labview. Something like DSO. I can do this in NORMA View (which is developed in labview), but when i try to make it in labview with lnopa01 v09 drivers it doesent work. When I try to do do measurements it's ok, but when I try to record to memory and read then it returns error.

Hello Gmilek,

Thanks for posting at NI forums! Basically, you can acquire measurements using LabVIEW, but when try to log the data to a file, it gives you an error? What is the error code you are getting and to what file are you trying to write to?

Best Regards,

You have wired the 0.05 constant to the record length input.  I'm assuming wiring that to pretrigger length instead will fix the problem  ( And a little BD Clean-up would go a long way):smileywink:

I tried to wire pretrigger, but it didn't fix the problem. It returns this error every time. Memory is empty and it cannot read anything from it. I dont know how can i make norma 4000 start writing to its memory?

memory trigger was missing...case solved

I'm looking to do something similar with a Norma 4000, would you be able to post your working code? Thanks
