=High 60 Hz noise=
Oh, so, so many things it could be.
# Make sure that the cases of the two +5 V power supplies (one for the heater fan and the other for the LCD screen) are not touching. I've seen this generate HUGE 60 Hz noise magnetic fields.
# Make sure the Tristan computer (to the left of the desk), Tristan NI chassis (inside of the shielded room), and chassis fan (controlled with the red and black striped power cable plugged into the white surge protector just behind the laptop) are all turned off. If any one of these is still on, again ask Sarah or Bill if it's OK to turn it off.
