analog triggering for noisy digital clock

[Gregory_Choong]

Help I need somebody!!!
I think for most of you it will be a really simple problem but not for me!! The attached file is my old application where i used to acquire the signal with a digital extern trigger on PFI2 Line, the problem is that for an unknown reason the digital trigger has crosstalk with an another clock (not in this vi), so I decided to use a Lowpass filter, and it works fine I have no more noise but the problem is that my rising slope is now too slow, so I want to use Analog trigger for my application but I can't configure a High Hysteresis analog triggering mode (HighValue:3V;LowValue:0.5V) !!!
How do I configure that ??
Is it possible with the signal clock on the PFI2 line??

Thanks
