This! +1000 times! Very important point!

Many thanks for the comments.

Yes, I agree, I already have a DSO scope (not very good) and I'll save for a analogic one.

Maybe an Hameg HM408 or a Tek 453 or a Philips PM3267 at about 100€. Witch one would be most recommandable for audio repair only ?

Hello all
I've bought THS730 version of the scope and after successful calibration it shows a ripple about 40mV peak-to-peak and the DC offset flows with time between -20..+20mV

Is any way to improve it ?

Thank you
