i was experienceing some problems using the analogue channels in our DL1.
this is just a simple 5 -12vdc signal applied on... off, on, off, on, off applied to each of the 8 ananloge channels. this data should not look like this.

reflash, new config in DL1
analysis reset to factor defaults
no filtering applied

check that the rate of change filter is turned off under advanced - to turn this off, you need to set it to "0".

all filtering is turned off
max rate of change is turned off, (non set, 0)
smoothed over: none set (0)

In 7.5 I think it is under Data/Analysis Options but can't remember exactly where. In 8.5 it is per Variable in variable manager.

looks like interpolation was turned on... but channel 2 and 5 are still "messed up" they should look the same as the rest of them
