Powetmeter connection

[Zxxxxvz]

I want to get the result of the power meter in LabVIEW and see the result. The power meter has an analog output jack that can be connected with an rca cable. When it is received as daq, only the waveform of the certain period is seen. I do not know why the result is this way. I am using nielvis2. The Power Meter is the first product in the search for 'Reduced Price LMC System Kits' on Google. (Company name : coherent)

Well, there are possible reasons. First, you should check the AI channel with a pure signal. So if the waveform is seen well, DAQ will be not the reason. Next, do test the power meter with other DAQ or DMM. Through this check, you would find where the problem is occurring. Perhaps, your code could be a reason. I recommend you to use the example provided by LV.
