I am using SCXI-1202 with terminal block SCXI-1303 to measure temperature by thermocouples and microvolts by heat flux seosor. Before the signal gets to the SCXI-1102, I applied an amplifier. The signals are good enough.
For my case, I need to do some signal analysis. The ideal signals are like this: the baseines for different conditions should be similar; the differences come form the range of the fluctuation.
However, when I changed the operating conditions, the base line of the signal changed a lot, and the fluctuations did not change much.
Is there anyway to fix the baselines and keep the fluctuations change base of the measurements?
