Procedure

A. Low Voltage/ Bias Control

In preparation for the tests, set-up the WIENER power supply (readout power and bias supplies) under computer control.
The readout supplies (channels 0 and 1 of the 8008L module) should be set to 5V and the bias supplies (channels 0 through 4 of the ISEG module)
should be set to the respective bias operating voltages from the SiPM channel chart.

    1. Connect the 37 pin power cable to the WIENER 8008 power supply slot 2, CH 0-3.
2. Connect the redl Bias cable to the iSEG module slot 1, ch 0-15.
3. Turn on the WEINER MPOD main power stitch.
4. Open iSEG SNMP Control Version 1.1.5.0 software.
5. In the File Menu, click select controller and use the following IP address:
> Delete what is there > Add 192.168.0.0
6. The software will populate the currently loaded iSEG module and 8008 module.
7. Refer to the BIAS and power channel excel maps to load the correct voltage for the SiPM channels that you are currently testing. NEVER ENABLE THE BIAS WITH THE DARK BOX DOORS OPEN
8. Close the LED dark box doors cover with black felt blanket.
9. Once voltages have been confirmed, connect the appropriate signal cable to the oscilloscope channel
10. Enable the LED pulse generator with the settings in part B of this guide.
11. Record the confirmation of a signal present
