# Return to the front side of the array and enable both of the lasers using the SRS LDC501s (left: '''pump''', right: '''probe'''). TEC first, laser diode second. The devices have been set up to not allow laser output unless the TEC has been enabled first, anyway. Both lasers are fiber-coupled into their respective TAs, so by activating the diodes, you're not yet sending any light into the room.
# Power up the laptop. The username to use is '''BioMag''' and the password is '''biomag'''.
# Set up an oscilloscope. Use one of the long power cables connected to one of the rack power strips (bottom right on the back of the rack) to ensure that the scope shares a ground with the rest of the electronics. Connect a bundle of four BNC cables between the green BNC ports on the FPGA breakout box and the scope. The green BNC ports are in ''parallel'' with the FPGA inputs, and will provide a "monitor" for the data the FPGA can record.
'''At this point, the setup is "ready to go" and data collection can begin as soon as the cells reach temperature. As long as the "current/thermistor" cat5 cables are plugged into the main box, the temperatures can be read by attaching a resistance meter to the green Temp BNC port.'''
