POWM test on D-BL10WF|80W

I have a DBL10/80W blue laser and would to test this thoroughly using my Benchtop PWM Generator. I can the plot a graph for future refence. The generator produces 5v PWM signal. and Frequency. I’d like to do this before fitting the laser diode to my 70Watt CO2 laser machine. Has anyone done this? Wheres a good starting point ?
