Forum Post: ADS1298R PGA Gain

I have the MMB0 and the ADS1298R software evaluation package, I started to feed in signals into my inputs and when I set my channel control registers to different PGA gain, it doesn't seem to be doing anything.  Here are a couple of screen shots:

The first one has a PGA gain of 1

and the second one a gain of 12

am I missing something?

I also included a SS of my channel control registers

any suggestions would be appreciated, thanks
