Title: My DSO 2090 channel 1 DC coupling is not working [Print this page] Author: spectrum53 Time: 2019-8-24 16:59 Title: My DSO 2090 channel 1 DC coupling is not working Dear Support, my DSO 2090 channel ! DC coupling is not working correctly, AC coupling and GRD seem to work ok, but not DC coupling. It's almost like it is still AC coupled. There is a slight offset present in AC coupled. Is there anything I can do, or do you do a repair service? See attcahed image. Channel 2 is working correctly.
