We have your USB-1208FS-PLUS for an application we are working on and we would like to see if there is any way we can get a clock signal output at 20Hz through this device. From reading the support pages it seems like we can get a SYNC output of the internal A/D pacer clock. I know there is a dynamic clock input range but I was not sure if this internal A/D pacer clock is adjustable. It seems to be able to be altered through an internal software set up, but I was not sure. If this is not possible then can you please recommend one of your product offerings that also has Analog and Digital I/O peripherals.
