log square wave period

[programmindragon]

I am reading a square wave from a motor and want to log at least 100 data points of a single period.  I only want to capture one period from rising edge to rising edge.  It is not critical when this sample is taken.  I would rather wait a few seconds for the motor to stabilize before I capture this period.  This signal is coming in at 133 hertz so to get 100 samples of one period, i need to read at least 13,300 samples/sec.

I am running LabVIEW 8.2 on Windows XP and using a PCI 6221 to read my signal.

Here is what I have now:

Thanks in advance for your help.
