A new element is introduced in the setup: an oscilloscope. Its channel 2 is connected to the analog output port number 2 of the OPX controler. A RF signal of frequency 100MHz and duration 9\mu s is sent to the oscilloscope. To take into account the raise time for the AOM, the RF pulse has a longer duration of :math`10.12mu s`.
Not written in the config file, the photo-diode is plugged on the first channel of the oscilloscope.
The experiment is repeated for different values of the amplitude sent to the AOM. The amplitude is ramped from 0 to 0.5V with steps of size 0.00025V (2000 steps). The RF pulse is sent to the AOM. 120ns later, the trigger pulse is sent to the port channel 2 of the oscilloscope, launching the acquisition on channel 1. We acquire 10\mu s of signal and make the mean of it. When both operations are over, repeat the experiment. We measure intensity function of the voltage.
