why do oscilloscopes never have very good math functions
you can add or subtract or multiply waveforms but if you want to do A+B+C well too bad you need to do math1=A+B and then math2=math1+C
want to do A+B+C+D? too bad you can't, that would need three math channels and you only get two

@noiob all software.
you can do more advanced stuff on tektronix scopes, and some of the extra fancy ones from keysight/agilent let you use arbitrary matlab code to make custom math functions but we don't have either of those

@noiob (we have a lecroy scope at work. probably going to get another lower-end scope too in the near future because we're sharing it with a coworker and both of us keep needing it for different things. so now we need to figure out what a good scope would be)

@Felthry be careful, don't wanna fall victim to scope creep ;)
@Felthry wait are they actually adding the signals then resampling them? that'd make sense then
if it's all software then the reason is software developers are lazy, I should know
