Sorry martyn,
I had not yet seen your message, removing the low-pass filtering on the analog channel D, the signal is no longer shifted and is well synchronous between analog and digital channel
Thank you ! I let you do

Hello I unplugged the picoscope from its power supply and USB port for 30s I redid a measurement under other conditions: The analog channel A on a radio signal (data RF) AND the analog channel D12 on the same signal Data RF This time, we see the shift (63us) on the entire signal Look at the attached...

Hello

I saved only this psdata file, but it shows the problem, I could redo the manipulation if necessary
Thanks

Yes, it's the same signal connected to analog and digital signal
Look the pulse on P31 (digital channel (green)) and on channel B (red) is the same pulse : time shift =70µs

Hello
As the title says, for the same signal connected to an analog channel and to a digital channel, there is a shift between the two signals of 70 μs.
The hardware is a Pico 3403D MSO-Version 1.7.5.0 / 1.0.66.0
Thanks for your help
