Calculate subsystems

There are three Calculate Subsystems. The CALC1 Subsystem is used for math expres-
sions, CALC2 is used for limit tests, and CALC3 provides statistical data on readings
stored in the buffer. The commands in these subsystems are summarized in
CALCulate[1]
NOTE Percent deviation (%DEV) is included in the catalog as a built-in math expres-
sion but is only available from the front panel. However, percent deviation can
be added as a user-defined math expression for remote operation
examples").

CATalog?
:CALCulate[1]:MATH[:EXPression]:CATalog?
Description This query command is used to list the math expression names. This list
includes the built-in expression names as well as the names of expres-
sions defined by the user. The names for the built-in expressions are as
follows:
"POWER," "OFFCOMPOHM," "VOLTCOEF," "VARALPHA,"
"%DEV"
Thus, the :CATalog? command will return the above names as well as
the names of any user-defined expressions. See
