Preface
About This Manual
This manual provides operating instructions for the RSA3303B, RSA3308B, and
RSA3408B Real-Time Spectrum Analyzer Option 30 3GPP Release 99 and
Release 5 uplink and downlink analysis software.
This manual supports the following instruments:
RSA3303B Option 30
RSA3308B Option 30
RSA3408B Option 30
The manual consists of the following sections:
Getting Started describes the overview of the 3GPP Release 5 analysis.
Operating Basics explains the menu functions and measurement procedures.
Appendices provide additional information about default settings and scale
setting ranges.
The analyzer uses Microsoft Windows XP as the operating system. This manual
does not describe common usage of Windows XP. Refer to your Windows manuals
as necessary.

ACLR Measurement
3GPP-R99/R5 Spectrum Analysis
The ACLR (Adjacent Channel Leakage Power Ratio) measurement according to
the 3GPP-R5 standard is based on the ACPR measurement function in the normal
spectrum analysis. For the basics, refer to ACPR Measurement in your instrument
user manual.
The following settings are fixed according to the 3GPP-R5 standard:
Span: 25 MHz
Main channel measurement bandwidth (Main Chan BW): 3.84 MHz
Adjacent channel measurement bandwidth (Adj Chan BW): 3.84 MHz
Channel spacing (Chan Spacing): 5 MHz
After selecting ACLR in the procedure described on page 2-2, set the parameters
in the Meas Setup menu as follows.
Measurement Setup Menu
The Meas Setup menu for the ACLR measurement contains the following controls:
Sweep.
On. Default. Acquires an input signal with five scans by the channel spacing
Selects how to scan the 25 MHz span for acquiring an input signal.
(5 MHz).
Off. Acquires an input signal with a single scan in the 25 MHz span.
Noise Correction.
Determines whether to subtract the noise level from the
signal level to obtain the measurement results.
On. Measures noise level first, and then subtracts the noise level from the
signal level to calculate ACLR measurement values.
Off. Default. Calculates ACLR measurement values directly from the input
signal level.
Measurement Filter Shape...
Selects a filter shape:
Rect (rectangle) or RootNyquist (Root Nyquist, default)
Rolloff Ratio.
Sets the roll-off value when the filter is Root Nyquist.
Range: 0.0001 to 1 (default: 0.22)
Limits...
3GPP-R5 only. Sets the pass/fail limit for the ACLR measurement.
When you press this side key, the measurement limits editor appears. Refer to
Editing the Measurement Limits on page 2-14 for more information.
NOTE.
The ACLR measurement and the multi-carrier ACLR measurement use the
same limits setting.
