problems with time scale of arb wave form

Hello,

I created an arb waveform. Within Labview I can also change the time constant. However, on the hardware (USB-6361 with 10MHz DIO) I receive only 1ms impulses instead of 100µs impulses.

Currently I am working on a Labview Evaluation Licence. The  full labview licence is installed and available at the licence manager, however there are some problems. I am working on that. I mention this as this might also be the reason for my hardware problem.

I included the VI. The first two analog signals are for creating a certain reference and supply voltage. The sencond one is the digital output which should be 100µs instead of 1ms which I measure with the ocsilloscope.

Thanks.
