Vector Signal Analyzer
Data Sheet
The Agilent Technologies E4406A vector signal
analyzer (VSA) is a full-featured transmitter tester
designed to meet the test needs of wireless equipment developers and manufacturers. For wireless
base station, mobile transmitters and their
components, the easy-to-use E4406A provides the
best combination of speed and accuracy for a wide
range of digital modulation analysis capability.
And, with multiformat capability (W-CDMA,
cdma2000, 1xEV-DO, cdmaOne, EDGE, GSM, NADC,
and PDC) the E4406A is the ideal, flexible choice
for your production line.
Easily configure one-button measurements with
the simple, straight-forward menu structure and
view them on the large, high-resolution color display. With built-in, standards-compliant tests and
state-of-the-art digital IF technology, engineers can
be confident that test results are accurate. And,
when combined with the Agilent ESG series of
digital RF signal generators, the E4406A VSA provides a powerful, transmit-receive test solution for
wireless-equipment manufacturers.

3GPP standard.

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.

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.

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.

QPSK EVM measurement
Modulation accuracy measurement (composite EVM)
The QPSK EVM measurement measures the modulation
quality of QPSK modulated signal. This measurement provides an IQ constellation diagram, error vector magnitude
(EVM) in RMS and peak as well as magnitude error versus
chip, phase error versus chip, and EVM versus chip.
Composite EVM is a measure of the performance of a
W-CDMA transmitter’s modulation circuitry. Composite
EVM can be measured for a pilot channel along with other
channel structures, i.e. multiple traffic channels.

The intermodulation distortion measurement determines

and a modulated W-CDMA signal. The results are displayed
in relative power to the carrier in dBc or in absolute power
in dBm.

Spectrum emission mask measurement
Absolute power measurement
Using 5 MHz resolution bandwidth
The spectrum emission mask measurement measures
the in-channel and out-of-channel spurious emissions to
provide useful figures of merit for spectral regrowth and
emissions produced by components and circuit blocks. Up
to five pairs of offsets/regions can be defined in which the
user can specify the start and stop frequencies, resolution
bandwidth, and the start and stop amplitudes of the mask.

Multicarrier power measurement
This measurement is used for adjusting multicarrier power
amplifiers to transmit well balanced multiple carriers. The
measurement is similar to a combination of those for ACPR

giving in-channel and out-of-channel performance results.
The results are displayed for the different frequency offsets

power in dBm.

Modulation accuracy (rho) measurement
Adjacent channel power ratio measurement
Rho is a measure of the performance of a cdmaOne
transmitter’s modulation circuitry. Rho can be measured for
a base station only when a pilot is the only active channel.
Rho can be measured for a reverse channel offset-QPSK
signal when the data is all zeros going into the short code
spreading. Error vector magnitude, time offset, frequency
error, and carrier feedthrough are also measured and
reported.

Power versus time measurement
Power versus time measures the average power during the
“useful part” of the EDGE or GSM burst and verifies that
the power ramp is within the EDGE or GSM mask. The
specified EDGE or GSM masks for both base transceiver
stations and mobile stations are provided. Power versus
time also lets you view the rise, fall, and “useful part” of
the burst. The timings are referenced to the transmitter
from bit 13 to 14 of the training sequence (midamble).

due to switching transients (burst ramping). A single offset
can be examined with a corresponding trace, or up to 15
offsets can be measured with a tabular data display.
