| analogRF:
here are the pictures of the main board of the scope front and back I have assembled the unit now but I can open it again and try... I did scope around those marked connectors/headers but I did not see any activity at the time (when the scope was still corrupted) |
| analogRF:
this is the back side |
| analogRF:
it seems upgrading the BW needs the board to be replaced or the front end be tuned and/or some passives in the front end to be replaced these scopes had 350MHz,500MHz,750MHz models but I think the board must be the same except changes in the front end under those shields plus some ID resistors perhaps? because there is no bandwidth license... |

As you see in the picture all 4 traces have a red line overlay on them and at higher V/div when noise is not visible and trace becomes thin the red line completely masks the color of trace so they all look red!! >:( >:( >:( :o :o :o unless I STOP the trigger then I can see the actual colors has anyone seen this problem? --- End quote --- Problem ? Maybe you never had a DSO with color intensity display before ? |
