Product Description

This section provides an overview of the product capabilities.

The RSA3300B Series and RSA3408B Real-Time Spectrum Analyzer Option 26
is an analysis software option that adds transmitter measurements capability for
1xEV-DO forward link (3GPP2 C.S0032) and reverse link (3GPP2 C.S0033) to the
analyzers.

You can perform the following 1xEV-DO measurements:

 Modulation accuracy

 Code domain power

 Channel power

 OBW (occupied bandwidth)

 ACPR (Adjacent channel power ratio)

 Spectrum emission mask

 Gated output power (forward link only)

 Intermodulation

 CCDF

 Pilot to code channel

In addition, the option provides predefined measurement limits for the ACPR,
spectrum emission mask, and gated output power measurements. Using these
measurement limits, you can easily check that the input signal meets the
specification.

Modulation Accuracy Measurement

The modulation accuracy measurement measures Rho (ratio of the correlated
power to the total power), EVM (Error Vector Magnitude), magnitude error, phase
error, frequency error, and origin offset. Figure 2-2 shows an example of the
modulation accuracy measurement.

View Define me n u.

You can set the following timing parameters using the Acquisition/Analysis menu.
Press the Acquisition/Analysis key to open the Acquisition/Analysis menu.

 Acquisition (chips): Sets the acquisition length in chips. The range depends

on the acquisition memory size and the span setting.

 Acquisition Length (s): Displays the acquisition length in seconds.

 Acquisition History: Specifies the number of the block to display and

analyze. The latest block is number zero. Older blocks have larger negative
numbers.

 Analysis Interval: Sets the analysis interval in half slots. The range depends

on the acquisition length setting.

 Analysis Offset: Sets the start point of the analysis with respect to the left end

of the acquisition length in half slots.

 Spectrum Length: Displays the time length for FFT processing of the

spectrum displayed in the subview. This value is equivalent to one frame
acquisition length.

 Spectrum Offset: Sets the beginning of Spectrum Length with respect to the

left end of the acquisition length.

NOTE. Refer to your instrument user manual for detailed information about the

timing parameters.
