PERSONAL SPECTRUM ANALYZER
POWER MEASURE
The R3131A can measure the power within
the specified band of frequency diffuse signals
and the total power of multi-carrier signals. It
can also be used to measure the occupied
frequency bandwidth (OBW ) and adjacent
channel leakage power (ACP) which are
essential to transmission characteristics testing
for radio equipment.
Channel Power
The R3131A allows you to measure the total power within the
window and display it as the channel power simply by setting
the measurement window to the specified occupied bandwidth.
Total Power
Obtains the total power from the spectrum displayed on the
screen. This function is useful for total power measurement of
multi-carrier signals.
OBW
Measures the frequency band which contains 99% of the total
power of the spectrum displayed on the screen. In addition,
the % value of OBW can be set to any desired value.
ACP
The measurement results can be displayed in graphical form,
including upper and lower point data, up to the 2nd ACP,
respectively, offset from the carrier and leakage power value at
all the displayed frequency points.
