ACPR
The adjacent channel power ratio (ACPR) measures
the power ratio between the main channel power
and the adjacent channel power.
ACPR measures the total power (RMS voltage) in
the specified channel. The measurement result
reports the ratios of the two adjacent channel
powers to the main channel power.
Center Frequency
Key access: [MEAS] > {ACPR} > {Center Freq}
Sets the center frequency of the main channel
power.
Main Channel
Key access: [MEAS] > {ACPR} > {Main Channel}
Specifies
the range of integration used in
calculating the power in the main channel. Use the
knob, the arrow
keys, or the numeric keypad to set
the bandwidth.
Adjacent Channel
Key access: [MEAS] > {ACPR} > {Adj Channel}
Specifies the range of integration used in
calculating the power in the adjacent channel. Use
the knob, the arrow keys, or the numeric keypad to
set the bandwidth.
Channel Space
Key access: [MEAS] > {ACPR} > {Channel Space}
Sets the space value between the center frequency
of main channel power and that of the adjacent
channel power.
