I have seen some strange behavior on my SCXI-1126 module. We were getting wrong readings. The input signal should have been about 1.3 kHz but my channel was reading about 21 Hz. Even when using a signal generator to create a nice square wave going into the card, this would happen.
I had the range set up in the MAX test panel as 0-2000 Hz. When I changed the range back to the default (18kHz or whatever it is) the signal suddenly started reading correctly. What's even stranger is that then I changed it back to 0-2000 Hz and it continued to read correctly.
It almost seems like the 2000 Hz setting is rejected, but the 18 kHz setting is accepted, and once applied, sets something inside the module so it reads correctly.
Maybe there is something about the 1126 I am not understanding, but I thought I'd ping the community and see if anyone else has seen anything like this.
Thanks
