measure current frequency

hi, can someone help me... i am doing aproject to count a current pulse and the data can be manipulate to get the pulse frequency..the sensor i use is tetronix A622 current probe(http://www2.tek.com/cmsreplive/psrep/13510/60W_15081_0c_2009.05.15.11.07.56_13510_EN.pdf) and i have a daq 6024 and daq 6008 series..can someone please give me an idea how can i done this...i had try with counter vi but it seems the vi only can coun squre wave and can't count current pulse wave

Use DAQ Assistant to acquire signal from Analog Input, and use Tone Measurement VI to measure its fundamental frequency, but be reminded that highest measurable frequency is analog input sampling rate/2.
If you wish to measure higher frequency, you must build a pulse shaping circuit and input pulse to counter for frequency measurement.
