W-CDMA (Option E4406A-BAF)
Channel power measurement
The channel power measurement measures the total RMS
power in a user-specified bandwidth. The following specifi-
cations apply for the default bandwidth of 3.84 MHz for the
3GPP standard.
Minimum power at –70 dBm (nominal)
RF input
Absolute power accuracy, ±0.63 dB
18 to 30 °C
(±0.41 dB, typical)
Measurement floor -73 dBm (nominal)
ACPR measurement (ACLR)
The adjacent channel power ratio (ACPR) measurement
measures up to five pairs of offset channels and relates
them to the carrier power. The measurement result is a
ratio of the channel power to the power in each offset.
The results can be displayed as a ratio to the total power
in each bandwidth, or as a ration of the power spectral
density. Simulated spectrum analyzer mode is for those
who are accustomed to spectrum analyzers.
Minimum power at –27 dBm (nominal)

–42 to –48 dBc with optimum
mixer level
BTS 10 MHz ±0.82 dB, at ACPR range of
–47 to –53 dBc with optimum
mixer level
BTS 5 MHz ±0.39 dB, at –48 dBc

Power statistics CCDF measurement
The complementary-cumulative distribution function (CCDF)
traces provide you with how much time the waveform
spends at or above a given power level. The percent of time
the signal spends at or above the level defines the
probability for that particular power level.
Minimum power at –40 dBm, average (nominal)
RF input
Histogram resolution 0.01 dB
Code domain measurement
The code domain measurement provides a tremendous
amount of information about the in-channel characteristics
of the W-CDMA signal. Code domain power (CDP) view
directly informs the user of the active channels with their
individual channel powers. The CDP view also leads you to
symbol rate analysis such as symbol rate EVM and symbol
power versus time.
