This functional index categorizes the programming commands by the type of function that the
command performs. The functional index contains the following information: the programming
command mnemonic, the softkey or front-panel key that corresponds to the command’s
function, and a brief definition of the command. Once the desired command is found, refer
to the alphabetical listing of commands later in this chapter for more information about the
command.

as linear units, without changing the
reference level.
UAX UXR LVL Specifies the maximum signal level that
is applied to the input mixer for a signal
that is equal to or below the reference
level.
Sets the normalized reference level.
EXTERWAL PREABPG Subtracts a positive or negative
preamplifier gain value from the
displayed signal.
PRESEL PEAK t Performs a preselector peak.
Resets the reference level to its
instrument preset level.
REP LVL Specifies the amplitude value of the
reference level.
REF I.‘& OFFSET Offsets all amplitude readouts without
affecting the trace.
AUTO ALL Couples the active functions
automatically.
CNTL A 0 1 Sets the control line A of the auxiliary
interface high or low.
CNTL I3 0 I Sets the control line B of the auxiliary
interface high or low.
GNTL C 0 1 Sets the interface control line C of the
auxiliary interface high or low.
CNTL D 0 1 Sets the interface control line D of the
auxiliary interface high or low.
DISPLAY CNTL I Returns a “1” when the interface
control line I of the auxlllary interface is
high, and “0” if the line is low.
