C
Calibration
A standardized maintenance procedure designed to ensure system accuracy. In this manual it refers to
removing those items that require calibration the DVM and the Frequency Counter and shipping them to
an Agilent bench site for calibration.
Card
As used in this manual, refers to printed circuit boards that are not installed VXI mainframes. See
module.
Column Disconnect Relay
A series relay on each of the four lines of the ABus that can be controlled either automatically or
manually. In automatic mode, the default mode, if any relay in the column is closed, then the column
disconnect relay is also closed; otherwise it is open.
Common Line
This refers to the power bus side of a load on the 24-Channel Load Card. A line is run back up to the
DUT load side of the card, and jumpering a channel's internal load terminals allows the user to utilize
the load switch as a GP relay.
Configurable
An instrument capable of having its values or performance modified to accommodate system
requirements.
Counter
A frequency counter, specifically the Agilent E1333A Universal Counter.
CtrCh1 and CtrCh2
CtrCh1 is the signal between the E1333A Counter Channel 1 and J3 row 11 of the Measurement Control
module. CtrCh2 is the signal between the E1333A Counter Channel 2 and J3 row 12 of the Measurement
Control module.
Current Sensing
Determining the current through a fixed, known-value resistor, using the four-wire measurement method
and deriving the current in amperes via the equation: I=E/R.
