Access Key Description
Selects absolute decibels relative to 1 µV as the
AMPLITUDE
amplitude units.
Selects absolute decibels relative to 1 mV as the
AMPLITUDE
amplitude units.
Adds an offset value to displayed frequency values,
FREQUENCY
including marker frequency values. The range of the
sweep (that is, the span) is not affected. When this
function is active an F appears on the left edge of the
display.
— Activates the center frequency (or the start frequency)
and accesses a menu of frequency functions.
Sets the spectrum analyzer span to its maximum
SPAN
frequency range.
— Holds the active function to its present value, blanks the
softkeys and active function area from the display, and
expands the remaining graticule and annotation.
Sets the spectrum analyzer to the previously selected
SPAN
span.
Selects the linear amplitude scale.
AMPLITUDE
Selects a 1, 2, 5, or 10 dB logarithmic amplitude scale.
AMPLITUDE
Selects the maximum mixer level seen at the input mixer
AMPLITUDE
for signals at or below the reference level.
Activates the normalized reference level, permitting an
AMPLITUDE
offset to be introduced to the displayed trace.
Adjusts the normalized reference position.
AMPLITUDE
Automatically peaks the preselector for the desired
AMPLITUDE
signal on a trace.
Permits manual adjustment of the preselector. Peak the
AMPLITUDE
preselector using the data keys, the step keys, or the
knob.
Activates the dynamic range level function and ensures
AMPLITUDE
the displayed range is compression free.
Activates the reference level function.
AMPLITUDE
Introduces an offset to all amplitude readouts, but does
AMPLITUDE
not change the position of the on-screen trace. When this
function is active, an R appears on the left side of the
display.
