Spectrum Analyzer Mode Key Descriptions
Spectrum Analyzer Mode Functions
CHANNEL
BANDWDTH
allows the user to enter the channel bandwidth to set up
the analyzer when using the measurement functions under
the Power Menu
softkey.
When the power measurements
are first accessed the initial value for channel bandwidth
is 16
kHz.
If the value is changed, the new value will be
saved through an instrument preset or power on. An error
message will occur for invalid values of channel bandwidth
and channel spacing.
If one of the power measurements is active and the channel
bandwidth is changed, with
PARAM
AUTO selected, then
the coupled analyzer settings are immediately updated. If
CONT
MEXS
is also selected, then another sweep is taken
and the measured results are updated.

CHANNEL
POWER
measures the power and power spectral density in the
channel bandwidth specified by the user. Two vertical lines
on the display indicate the edges of the channel bandwidth.
The measurement can be made on a single sweep or
to continuously update at the end of each sweep. The
center frequency, reference level, and channel bandwidth
must be set by the user. If
PARAM
AUTO MAN is selected
(AUTO is underlined), other settings will be coupled and
set automatically.
PARAM
AUTO
MAN can be selected to
manually control all settings by underlining MAN. The
measurement stops and the analyzer is returned to its
prior state when other functions are activated. The
channel power measurement responds like an rms power
measurement.
