The DSO7054A display does not indicate whether DC or AC probe coupling is selected. When a screen image is saved, this info appears to be lost, except that it can be determined from the setup text file -- but of course only if that save option is selected. I suggest that, for each channel, the 'AC' or 'DC' indicator should show on the display screen so that a screen shot contains all the important info needed for analysis, including any BW limiting and 50-ohm termination if used.
