record time of zero crossing

[Nigel91]

I am trying to record the time for zero crossing in order to get the phase angle and inevitably get the power facto . soi was trying out a few ideas to  see if this is achievable and i came up with this . can someone tell me where i am wrong . or what to do  get the right values ..

1. You need to pass the waveform into the Get Waveform Time Array.

2. No need to wire up the N on the FOR loop since you are using Autoindexing tunnels.

3. The Conditional Indexing tunnel is your friend here.

Thank you soo much for replying me .  but i have tried this and still unable to get it .. I want to get the time for  each instant the waveform crosses the zero point

Can't troubleshoot without your code.  But it looks like you did not pass the waveform into the Get Time Array function.

Here is my code

You missed the Conditional part on that autoindexing tunnel.  Right-click on the output indexing tunnel of the timestamps.  Now select Tunnel Mode->Conditional.  You now just wire up the output of the Zero Crossing to that conditional part of the tunnel.

I also recommend getting rid of the wait inside of that loop.  Just let it go as fast as it can.  It won't take long to run through this array, so I would not worry about it using up your CPU.

Thank you soo much . i have officially learnt something new about the conditional tunnel mode . first time i have heard of it . Amazed right now ..:manvery-happy:
