Hi

I have been reading through posts refering to 'adding a math channel'

Can someone tell me why I would use this option,how to set it up and what type of results I should expect to see and how they help.

I am sorry if this question has been answered in the past, I did have a look through but cant find anything.

Regards

here's a vrs ckp sensor subtracting the pos (cha) from the neg (chc) to form a true ckp representation in the math channel (pink).

it isn't required.  if you wanted a true representation of ckp on a vrs sensor you would have two choices.  one choice would be to use one channel across the ckp sensor, but if you do it this way you cannot use your other channels.  the other is to use math, but this means you are dedication 2 channels in order to get the math.  at least that leaves you with 2 other channels as long as you have a 4 channel scope.

this was simply an illustration on what a math channel is, and how it can be used.
another quick use for math is when you accidentally capture an upside down secondary capture.  just use an invert math channel to flip it over  .
