AMPLITUDE Y Scale
current amplitude scale. When Power On is set to Preset and Preset Type
is set to
Factory, pressing Preset or powering on the analyzer sets the
default units.
Key Access:
AMPLITUDE / Y Scale
Presel Center
Agilent E7403A, E7404A, and E7405A only. Adjusts the frequency of
the preselector filter (above 2.85 GHz) to optimize the amplitude
accuracy at the active marker frequency. If activated in a
non-preselected band, Presel Center does nothing.
Preselector center should be used to improve amplitude accuracy for
signals which fall into any one of the harmonic mixing bands. The
harmonic mixing bands Frequency Ranges are:

AMPLITUDE / Y Scale
Presel Adjust
Agilent E7403A, E7404A, and E7405A only. Allows manual adjustment
of the preselector frequency to optimize its response on the signal of
interest.
By changing the
Presel Adjust, the center of the preselector filter can be
moved in frequency. The signal of interest will appear to change in
amplitude with the frequency response of the preselector filter.

Y Axis Units
Accesses the menu keys that change the amplitude units. Amplitude
units are maintained for both logarithmic and linear modes. The
amplitude units can be changed by pressing
dBm, dBmV, dBµV, dBµA,
Watts
, Volts, and Amps. This key is unavailable when FM Demod and
Demod View are on.
