Test Adherence to Standards

Test Adherence to Standards
The following information describes the implementation of the measurements in the E1963A Mobile Test
Application and their compliance with established standards.

Thermal Power

Thermal power is an unfiltered, broadband RF power measurement, that is intended for the Maximum Output
Power test (3GPP TS 34.121, section 5.2). At the time of this writing, the 3GPP standard specifies that this
measurement be made over 1 timeslot (667 µs); however, the implementation of this measurement in the
Agilent 8960 requires 10 ms.

Channel Power

Channel power is a filtered RF power measurement, using a Root-Raised Cosine (RRC) filter with a rolloff of
α=0.22 , and a bandwidth equal to the chip rate (3.84 MHz). This measurement meets the requirements for the
following tests: Transmit Off Power (3GPP TS 34.121, section 5.5.1).

Adjacent Channel Leakage RAtio

Adjacent channel leakage ratio (ACLR) measures RF power at +/-5 MHz and +/-10 MHz offsets from the
carrier (center) frequency, using a Root-Raised Cosine (RRC) filter with a rolloff of α =0.22, and a bandwidth
equal to the chip rate (3.84 MHz). This measurement meets the requirements defined in 3GPP TS 34.121,
section 5.10, Adjacent Channel Power Leakage Ratio (ACLR).

Waveform Quality

Waveform quality performs the following measurements: error vector magnitude (EVM), frequency error,
origin offset, phase error, magnitude error. The frequency error result meets the requirements for 3GPP TS
34.121, section 5.3, Frequency Error.
For this revision of the W-CDMA test application , the error vector magnitude result meets the requirements
for 3GPP TS 34.121, section 5.13.1, Error Vector Magnitude, with the following exceptions:
• This release only supports the 12.2k reference measurement channel (RMC).
• Peak Code Domain Error (section 5.13.2.1) is not available in this release, since that measurement is
intended for multi-code signals and only one code is used in FDD test mode.

Frequency Error

Frequency error compares the expected uplink channel frequency to the measured uplink channel frequency,
and is included with the waveform quality measurement results. See "Waveform Quality" .
