Hello!
I'm trying to get a signal from the generator with DAQ and build its spectrum.
The signal is a normal sine wave frequency of 2 kHz and an amplitude of 4 V.
Hardware:
In computer installed board NI PCI - 6123.
Board connected with unit BNC - 2110.
The operating system is Windows XP SP 3.
Driver for the NI PCI - 6123 version DAQmx 8.6.1.
LabVIEW 8.5.
When trying to get signal an error:
"Error - 200284 occurred at DAQmx Read (Analog 1D Wfm NChan NSamp). Vi: 2"
The NI's site has a link to the solution of this problem https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P8XsSAK&l=en-US. I tried to change the Sample Rate, Timeout and Samples to Read, but it has not resolved the issue.
Driver board NI PCI - 6123 normal installed, the device detected by the operating system. On another computer with a similar card and software all works.
Please help me to solv this problem.

Are you acquiring finite or continuously? So what is the toplevel VI you are running?
What numbers for sample rate, samples to read and timeout have you tried out?
Using the MAX, do you see the signal in the Testpanel?
Another thing which might be an issues:
- External start trigger
- External clock

I am acquiring finite.
What means toplevel VI?
Sample Rate = 1M; Sample to Read = 100k; Timeout = 10s.
I don't see any signal on Testpanel.

And this you can see screenshot of LabVIEW Signal Express v. 2.5.

Sample rate is High it seems. PCI 6123 supports upto 500KS/s. You have opted for 1Msamples

I try to change Sample Rate but problem is still here. 😞
Sample Rate = 500k
Sample to Read = 50k
Timeout = 10s

Please post your VI.
Also, referring to your statement that another system works correctly:
"similar card": Is this also a 6123?
Do you use the same application there?
Do you see samples in the Testpanel there?
Are there differences, like e.g. different driver versions?
It is possible that you are encountering a hardware defect. Can you swap the devices between the systems?
