E6198B Switch/Load Unit User Manual
For example: If the UUT requires precisely 12 Vdc applied to
it, and there is a 0.5 Vdc drop between the power supply and
the UUT due to system and cable losses, setting the voltage
sense to remote and thereby monitoring the power supply
output at the UUT will compensate for the voltage drops
between the power supply and the UUT.
• Rs
Source resistance.
• Safety Shroud
A cover for the Switch/Load Unit that protects personnel
from possible contact with dangerous voltages on the
exposed PC board.
• Self-test
A test executed by an instrument or system on itself to verify
the functionality of the instrument or system.
• Sense
See: Current sensing.
• Slot Decode Logic
The circuitry that interprets the data that represents the
physical slot a load card occupies in a Switch/Load Unit.
• SLU
Switch/Load Unit.
• Stand Off Voltage
The maximum voltage differential an open relay can tolerate
without arcing across the contacts.
• Switching Voltage
The nominal voltage differential across a relay's contacts at
which it can be switched. The switching voltage is typically
much less than the standoff voltage.
• Unit Under Test (UUT)
The automotive module or printed circuit board being tested.
• VME
Computer backplane architecture standard.
• VXI
Computer backplane architecture standard that incorporates
both the VMEbus and GPIB communications features.
