I'm going to admit I never knew what trigger did before . . .
When viewing UART data I just asked my mcu to keep repeating itself . . . but this trigger thing makes me feel dumb now
Oh and you forgot to talk about the most amazing oscope button ever, Autoset!
Also nice are the scopes that have USB connections to your PC to upload saved waveforms. The current Techtronix ones however still use floppy disks . . .
