HI Martin, See the attached example: Non filtered noisy signal: 3.png I want to capture the voltage dip as a filtered signal : 4.png Unfortunately the scope triggers at any time when it sees a hidden noise peak: 5.png This is a common way when using "normal" digital scope (e.g. HP etc.). This exampl...

OK, there is a low pass filter which filters the input signal. But, the trigger is still capturing the original unfiltered input. So, the capturing will start when the trigger input sees e.g. input higher than the trigger level (mark), doesn't matter that the filtered signal is much lower: Non filte...
