Low Voltage Power Supply Project

ELMB_MB ProductionTester (for MB v.6.5., 6.5.3A)

The ELMB_MB Tester was developed in 2005 as a full-automated production test-bench. The tester simulates a real
environment inside of a finger LVBOX for the tested ELMB_MB. An automated production tester was designed to evaluate
functionality of each ELMB_MB manufactured in 300pcs.
The described tester has to check:
- CAN bus communication between ELMB module and a host computer via CAN open protocol.
- Simulated behavior of all connected bricks (3VDIG, 5VDIG, 5VMB, -5MB, 15MB, -15VHV, 15HV, 5HV)
         = Application and level checking of the Startup signal on each brick
         = Measurements of Three thermometers on bricks
         = Measurements of Input/Output brick parameters (Vin, Iin, Vout, Iout)
         = Checking enable/disable DIG/HV loops
         = Brick Vout DAC Trimming simulation on ELMB_MB motherboard
- simulation of five sense line signals of the TileCal drawer coming from 3VDIG, 5VDIG, 5VMB, -5VMB, 15VMB lines
- reading of two heatsink thermometers connected to ELMB_MB
- clock distribution to each brick for possible DC/DC switching synchronization
