NOTE
You can use the LIMIT hot key to analyze your measurements with the user-definable
limit and Pass/Fail indication. See "Setting limit for RF tests" on page 147 for more
information.
ACLR
The Adjacent Channel Power Ratio (ACPR), designated by the 3GPP WCDMA 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.
After configuring test parameters as described in the "Configuring test parameters" on page 134, your
measurement result is displayed on the screen as like the following example, Figure 56.
