Measuring ACPR
The adjacent channel power ratio (ACPR) measures the power ratio between the main channel power and the adjacent channel power.
Center Frequency
Sets the center frequency of the main channel power.
Key Access: [MEAS] > {ACPR} > {Center Freq}
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.
Key Access: [MEAS] > {ACPR} > {Main Channel}
Adjacent 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.
Key Access: [MEAS] > {ACPR} > {Adj Channel}
Channel Space
Sets the space value between the center frequency of main channel power and that of the adjacent channel power.
Key Access: [MEAS] > {ACPR} > {Channel Space}
