ACLR
The Adjacent Channel Power Ratio (ACPR) designated by the 3GPP LTE/LTE-A
specifications as the Adjacent Channel Leakage Power Ratio (ACLR), is the power
contained in a specified frequency channel bandwidth relative to the total carrier
power. It may also be expressed as a ratio of power spectral densities between the
carrier and the specified offset frequency band.

NOTE
If Lower Peak or Upper Peak indicates Fail, the mask line becomes red.
If the Trace View is set to Off, the Reference Power, Lower Peak, and Upper
Peak is not shown. If the Trace View is set to On and the Trace Type is
selected other than Clear Write, the Reference Power, Lower Peak, and Upper
Peak is shown with value and
