Atec Advantest-R3131 - Manual (Page 5)

POWER MEASURE
The R3131 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 R3131 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 the upper and lower point data offset from the carrier
and the leakage power values at all the displayed frequency points.
