• Working with the SiPM and the laser diode in the lab
• We don't have anything to digitize the signals with at the moment, so for now sending the SiPM signal direct to the oscilloscope
• Previously were having trouble reading the data out from the scope using a USB connection
  • Hooked the scope up to the ethernet switch so we could get it on the network
    • Currently: 10.44.45.11, but it will change if it gets switched off
      • Read it from: Utility > I/O > IPset
      • Follow directions here: https://siglentna.com/operating-tip/configuring-the-ip-address-on-the-sds1000-dl-cnl-and-more/
  • Connected with pyvisa -> open_resource('TCPIP::10.44.45.11::INSTR')
• Right now seeing some weird things in the externally triggered laser signals
  • 1. a delay of around 20 ns between the two
  • 2. oscillations in the signal (look like reflections)

• It does not work. Bad touchscreen. Rerouted VGA cable to a monitor to see how it’s behaving. SBC (the on-board computer) restarts once a minute on a loop, beeping once at the start. We checked bios and found nothing useful.
• 
• Deivid was able to enter the BIOS using what was most likely the delete key (maybe the escape key was involved too)
  • Seems like it uses Award BIOS / CMOS
