'''This section will cover everything up to the noise measurement, and will assume everything from the "Initial Setup" procedure has been completed.'''
=FPGA and Arduino "Reset"=
Before proceeding with a noise measurement, it is a good idea to measure the rubidium absorption in each of the cells.
# On the array, switch the detectors to SUM mode. This is accomplished by moving both the 4-socket leads from the detector and the 2-socket leads that carry signals out of the room to the set of header pins denoted by a '''Σ''' or '''+''' label.
# If not done already, turn on the TEC and LD for the probe laser diode (the right-hand SRS LDC501 controller).
