por qué cuando uso los puerto digitales de entrada de una DAQ keithley la respuesta es muy lenta?

quiero que se prenda y apague un led de labview de acuerdo a una señales cuadrada que le conecto a una de las entradas digitales pero no es capaz de leer frecuencias altas con rapidez (400hz), uso una daq keithley 3102.

 

o alguien a intentado hacer esto con la myDaq de national instrument y les funciona?

They speak Spanish there.  In terms of using a myDAQ to handle a 400Hz change, you won't be able to do it.  It's strictly software timed.  If the Keithly has hardware timing, you could pull it off. Otherwise, you won't be able to do so here either.  For NI DAQs, you'll want either the M or X Series cards.  They can produce counter outputs.
