JD780A Series Analyzers Figure 51 SEM measurement with WCDMA/HSPA+ signal analyzer 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 150 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 137, your measurement result is displayed on the screen as like the following example, Figure 52.
