Hi,
I having problem using PCI-6025E for differential measurement on my UUT (an audio product, BTL output).
I had switch to differential mode in MAX. Measurement connection positive (ACH0), negative (ACH8).
I able to get the RMS value and freq of the measurement however the waveform is not uniform (unable to get beautiful sinewave).
When I use Scope to measure the UUT output, I able to get uniform sinewave.
I also tried to replaced the DAQ board however in vain.
May I know what can be wrong in my measurement?
Thank you in advance.........
Best Regards,
Norman
