AC or DC setting at scope? The signal in the first message has been captured in DC coupling . 1:1 has been selected in the Pre-Gain_Division stage. 1:1 has been selected in the Gain_Select stage. Hey, we are friends, aren't we? Nobody has to obey! By that , I meant I agree. thanks for your kindness. (Using Obey is just a bad habbit of me) Heaven, Farshid, that's looks really nice!!! TO be hunest , When at first I was posting the pictures I was typing some excuses for breakig the ground planes ! Now I am happy that you say theboard is designed good. I have to mention that I didn't saw any ground niose in the mV range so far ! I tried to do my best and use as much as I learnt about PCB desiging in this forum (mostly by your posts). The one, that bitscope uses. But this one will show a huge temperature drift. This would need to desolder the current parts(related to the offset section) and design a new circuit on a vero-board which may not look nice anymore. I will try the idea of paralleling a higher density Capcitor. Farshid |
