Greetings Amu,
How have you configured the PCI-6025E? Is it configured for
differential readings or single-ended readings?
By default, the configuration of the device will be differential,
which means that two input channels are used for every input signal.
When configured in differential mode, you need to connect the positive
terminal of the signal to channel X and the negative terminal of the
signal to channel X+8. For reading a differential signal from channel
0, you will connect the positive terminal of the signal to channel 0
(pin 68) and the negative terminal of the signal to channel 8 (pin
34).
I would suggest to use the Measurement and Automation Explorer (MAX)
software to test the signal before going to LabVIEW. Open MAX and go
to the devices and i
nterfaces folder. The PCI-6052E should be located
in this folder. Right-click on the PCI-6052E and select test panels
and you will be able to test the input signal here. You can change
the mode to continuous and set an sampling rate in the test panels as
well.
Once you can view the signal in the test panel of MAX then I would
suggest to move to LabVIEW. Search for the shipping example entitled
'Cont Acq&Chart (buffered) VI' which is a continuous analog input
example. Select the device number, channel number, and scan rate and
run the VI.
For more information on connecting your signals to the PCI-6052E I
would suggest to refer to chapter 4 of the user manual. I've linked
it below for your reference.

I hope this helps.
Let me know if you have any additional questions regarding this issue.
