combining channels in VI (ctr1 & ctr0)

Hi,
how I am suppose to divide the signal. initially it starts and then display this message. Of dividing the signal. where is divisor?

Hi,
all these months I was working on the soft ware to gather information, I used to receive the error that data was overwritten before could be read by the system.
Problem is my BNC 2120 is acting like antenna and picking up RF from my motors as motors are slow it works fine as motors speed increases my encoder signal and range sensor signal catches that RF and generates that error.

I changed the wires to insulated and shielded wires but still the moment I plug BNC 2120 into sensor I can see my sensor which has emitting led goes flat rather blinking.

What should I do? with BNC 2120 to stop behaving like antenna

Maybe I missed something, but how do you know that your sensor isn't picking up this high frequency signal? Maybe the BNC 2120 doesn't have anything to do with it?

Hi,
I am using a robot and all these motors and sensors are controlled by micro controller now the signal which goes into basic stamp II( micro controller) same signal goes into DAQ Card via BNC 2120. so I have two displays infront of me one is basic stamp editor and other is lab view Vi. so if I am looking at range then I can confirm in both ( basic stamp editor and labview Vi)

Now I have seen that my basic stamp editor works fine if motors are runing even at there fastest speed ( high voltage) and LED of range sensor blinking steadily but the moment I will plug the signal wire in BNC 2120 the LED will become very fast infact will glow continously.

I though that there is some ground looping occuring somehow. I am using two power supplies one for basic stamp and one for motors and computer is also connnected to power socket, so three things are actually being grounded and it is making one big loop.
So I decided that instead of using power supplies let me use 9V batteries so I attached batter to my micro controler and motors but the problem stayed as soon I power motors and if wire is going into BNC sensors LED becomes contionous glowing and if I remove the wire of BNC then LED blink as it is suppose to blink.

I hope now you understand my problem better.
Thanks
