The Chroma 42010
is a dual-channel multipath fading simulator
that accurately reproduces conditions in which
frequency-selective effects are not
significant. In other words it simulates
channels that are commonly termed narrowband.
However, the frequency-selective fading with
standard time-delay spread for WCDMA/ cdma2000
and GSM (6~12 tapped delays) are also
available upon request. The simulator is
capable of generating signals with both
Rayleigh and lognormal fading components and
offers an exceptional degree of flexibility
and simplicity in selecting the required
channel parameters.
The MFCS 42010
has been adopted up-todate technologies that
makes it simple to test a full range
multi-mode handset through the user defined RF
scenarios, especially for smartphone
calibration tests.
This product
can fully support WiMAX mobile performing the
simulations for 1 x 2 SIMO antenna design over
1.25MHz-10MHz band width with Jakes multipath
fading channel.
The
incorporation of both Rayleigh and lognormal
fading makes the Chroma 42010 ideally suited
for measuring the effects of multipath
propagation and co-channel interference and
for testing the effectiveness of micro and
macro diversity systems. Expandable wideband
channel models can be characterized for Rake
receiver, MIMO multiple antennas, and
beamforming system designs. The instrument
replicates real-world conditions, making it
possible to validate performance issues early
in the development and design cycle, and
calibration tests in the production line.
