Universal Interference Emulator
TAS5600
Dramatically simplifies the test
setup required for compre-
hensive receiver performance
analysis.
Wireless equipment’s mitigation of the
effects of co-channel and adjacent
channel interference directly affects key
performance metrics such as capacity,
quality, and coverage. A receiver’s
performance must be characterized over
a variety of channel conditions that
reflect real world operating conditions.
This characterization must be done
precisely, as small differences in receiver
performance can have a dramatic
impact on performance metrics.
Uncertainty in test conditions leads to
an even greater uncertainty in test
results.
Creating a test setup for today’s
wireless receivers can be a challenging
task given all of the elements required.
Covering all types of real-world
interference requires combining signal
generators, noise generators, cables,
and RF combiners. The challenges
inherent in constructing a test rack for
receiver characterization include:
■ Interferer Phase Noise
■ Modulated Interferer ACLR
■ Test set VSWR interactions
contributing to amplitude
uncertainty
■ Signal-to-noise ratio accuracy
■ Receiver sensitivity testing
accuracy
■ Test set self-intermodulation
■ Test set repeatability and
reproducibility
■ Minimization of technical resource
involvement necessary to perform
the test
Spirent’s TAS5600 Universal
Interference Emulator addresses these
issues by combining all of the necessary
hardware to facilitate receiver testing.
The TAS5600 addresses critical receiver
test setup issues such as signal-to-
noise ratio accuracy, output power
accuracy, phase noise, ACLR, test set
VSWR interaction, and repeatability
over time and across multiple test
setups.
Specifically, the TAS5600 combines
the functionality of two high-
performance, low phase noise signal
generators, two arbitrary waveform
generators, two real-time signal
generators, a precision instrument
grade power meter, and high accuracy
RF attenuators, across multiple RF
channels to support diversity testing.
This powerful combination of hardware
is housed within a single rack-
mountable chassis.
Benefits:
■ Increases confidence in test results
■ Reduces test time
■ Assures repeatable results over time
and across multiple test setups
■ Integrates of all receiver testing
components eliminating unweildy
test setups
TAS5600 is a
powerful,
integrated
solution for
evaluating receiver
performance.
Major Features:
■ Precise, repeatable C/N and C/I
emulation in one integrated
instrument
■ Application-specific UMTS and
CDMA2000 interferers
■ Integrates functionality of multiple
signal generators, attenuators and
measurement devices
■ Signal generation engine with long
data sequences for maximum
confidence in test results
■ GSM modulated inteferer, with
optional fading, is ideal for dual
mode test applications
■ Combines with Spirent’s SR5500 to
provide fading conditions necessary
for complete receiver testing
■ Two independent RF channels for
receiver diversity testing
■ Maintains signal path during
calibration cycle to speed up test
execution
■ TASKIT ® software provides easy
setup and control
