Where can I buy, is to be installed at the probe, how much cost?
Its usually in the probe accessories when buying a new probe. Along with channels color rings & square wave alignment plastic screwdriver. But you can make from wire or maybe find on line as "ground spring". Example: PK1-5MM-118 Teledyne LeCroy | Test and Measurement | DigiKey
It goes on like this:
I have 1 choke common mode 2x2mH 3A 250V, could I use it or do you recommend only RCRC?
It could be LC also, yes. You put between reg & FF, LC or RC, and watch scope for if it helps and for manipulating to best result.
I will do tomorrow and let you know, now it's too later, for C values the mains filter cap that I have now is 2.200uF, have to use another one the same value 2.200uF or can I use some small value, or it's important keeping both caps the same value?
So you have raw DC outboard of the regulators and you tried the rail filtering in-between the raw and the regulators?
FF rather easily picks EMI. If the Vout rail will remain so good on the scope, then win win. I.e. the filter worked and not necessarily put at the end point imposing its capacitor characteristic to Vout
I don't see difference on the scope, so listen for it to decide. LC sometimes is preferable on analogue applications but I don't know what a Flip Flop can care for
Leave it there then. It does not look worse than with the RC on the scope for sure. But the scope is not AP analyzer to show deeper differences.
