E6198B Switch/Load Unit User Manual
• Glitch
An unexpected or unplanned event or occurrence. Abrupt
termination of tests is usually due to a software glitch.
• GP
Acronym for General Purpose. The relays on the E6177A
24-Channel Medium Current Load card can be configured as
GP relays.
• Hardware Configuration
The physical and functional arrangement of the system
components with respect to each other. Refers to the relative
placement of modules load cards in the E6185A Switch/Load
Unit.
• Isense + and Isense -
The Switch/Load Unit has a two-line current sense bus along
the Switch/Load Unit backplane. This Current sense bus can
be broken into as many as four discrete buses by removing
jumper plugs on JP1, JP2, and JP3. Current sensing is
performed on any load card channel across a four-terminal
current sense resistor. Two load cards are designed to
connect to the current sense bus in the Switch/Load Unit:
The 8-Channel, and 16-Channel High Current Load Cards.
Each channel's current sense lines are multiplexed so that on
each card only one channel at a time can be connected to the
Switch/Load Unit current sense bus.
• Isolated Inputs
Inputs that have the common connected to system ground.
• ISrcHi and ISrcLo
The signal between the E1411B DMM "Current Source"
Channel and J3 row 3 of the Measurement Control module.
• LADDR
Logical Address - The address set on a VXlbus module that is
unique to that system. This usually corresponds to its slot
number.
• LEM Module
A current transducer with multiple primary coil taps that
allows it to be set for five different current levels.
