Hi~
In previously circuit design, we had an error in the reference voltage in our circuit design. Currently, we have adjusted the reference voltage to 5V. The test results are still not as expected.
We are testing the signal with a pacing frequency of 4Hz, as shown in the orange box in the diagram. Pin 1 (for oscilloscope CH2) and pin 3 (for oscilloscope CH1) are being tested. If the signal is not clean enough, many signals are being identified as peaks erroneously. Could you please suggest adjustments to improve the results?
