Access Key Description
— Activates the frequency span, sets the spectrum analyzer
to center-frequency span mode, and accesses a menu of
span related functions.
Activates the span width function and sets the spectrum
SPAN
analyzer to center-frequency span mode.
Tracks a marked signal and activates the span function
SPAN
so that the span may be reduced quickly without losing
the signal from the display.
Activates the start frequency and sets the spectrum
FREQUENCY
analyzer to start stop mode.
Activates the stop frequency and sets the spectrum
FREQUENCY
analyzer to start stop mode.
Accesses a menu of amplitude units. AUTO indicates
AMPLITUDE
default units for the amplitude scale are in use. MAN
indicates other units have been selected.
Selects volts as the display amplitude units.
AMPLITUDE
Selects watts as the display amplitude units.
AMPLITUDE
Sets the span to 0 Hz. This displays the input signal in
SPAN
an amplitude versus time mode which is especially
useful for viewing modulation.
Access Key Description
Selects the number of pairs of alternate channels for
MEAS/USER
an ACP measurement.
Calculates the occupied power bandwidth with respect
MEAS/USER
to the power between the markers.
MEAS/USER Makes ACP measurement using two different
resolution bandwidths.
AUX CTRL Selects the 0 V to 10 V ramp for J8 on the rear panel.
The 0 V to 10 V ramp corresponds to the sweep ramp.
AUX CTRL Selects a 0.5 V per GHz sweep output for J8 on the
rear panel. This is the frequency-analog voltage (FAV).
It is primarily used with external tracking generators.
AUX CTRL Selects an external (EXT) or internal (INT) frequency
reference. When external mode is selected, an X
appears on the left side of the display.
