Front-Panel Key Reference
Det/Demod
Det/Demod
Accesses the menu keys controlling detector functions, demodulation
functions, the speaker, and FM gain.
Detector Accesses the Detector menu keys which allow you to select between
Peak, Sample, and Negative Peak detection.
When
Peak detection is selected, Peak appears in the upper-left corner
of the display. Peak detection is used primarily when measuring
sinusoidal (spectral) components. Peak detection obtains the maximum
video signal value between the last display point and the present
display point and stores this value in memory. Peak detection is
selected at power on and by pressing
Preset.
When
Sample detection is selected, Samp appears in the upper-left
corner of the display. Sample detection is used primarily to display
noise or noise-like signals. This detection should not be used to make
the most accurate amplitude measurement of non noise-like signals. In
sample mode, the instantaneous signal value at the present display
point is placed in memory. Sample detection is activated automatically
for noise level markers or during averaging.
Negative peak detection functions the same as peak detection, but
selects the minimum video signal value. When
Negative Peak is selected,
NPeak appears in the upper-left corner of the screen. This detection
should not be used to make the most accurate amplitude measurements
of signals.
Demod Accesses the menu keys to select AM demodulation, FM demodulation or
demodulation
Off. It also accesses the Demod View On Off, Speaker On
Off, and Demod Time menu keys described below.
NOTE The FM menu key only appears when the FM demod option (Option
BAA) is installed. Option BAA is available on Agilent ESA-E Series
spectrum analyzers only (E4401B, E4402B, E4404B, E4405B and
E4407B).
NOTE Segmented sweep is not available with the demodulation functions in
this section.
