Hi.

i am working for a project and i need to measure the frequency of my generator with real time windows target. i got my pci 6221 adc board and want to try the Demo, named "Frequency Measurement" from the real time windows target. i set the "sample time" = 0.001 s, the "clock input source" to "internal clock 80 MHz" and the "Gate input functionality" to "enable when high, latch & reset on edge".
My generator builded a rectangle signal with +5 V - 0 V and 1 kHz. The problem is: when i simulate the demo, it comes out always -1000 in Display block.
i dont know why. Could anybody, who has the same experience, help me out of hier?

Thanks a lot.

Xian
