2 TAS5600 Universal Interference Emulator
TAS5600 combines precision interference generators, a power meter, attenuators,
signal combiners and a duplexer in one compact, easy-to-control instrument.
* The TAS5600’s digitally-modulated interferers include AWGN, WCDMA, GSM and CDMA2000 .
Receiver performance test setups
require multiple signal generators, RF
attenuators and signal combiners. To
increase level accuracies a
measurement device is typically
included into the test setup. A
calibration methodology, control
software, and maintenance are
required.
The TAS5600 addresses these
complex requirements inherent to
receiver testing. The TAS5600 is a two
channel instrument that combines
multiple signal generators with the
required RF components and an
instrument grade power meter to satisfy
receiver testing requirements. The
internal signal generators can be
configured to provide low phase noise
CW, popular modulated interferer types,
or AWGN. The two signal generators
can be combined and sent to one or
both channels, or used individually on
a per channel basis. The instrument
grade power meter within the TAS5600
automatically samples RF power levels
at multiple locations within the
instrument to assure accurate level
settings.
The TAS5600 has been optimized to
be repeatable over time to give
consistent results across multiple test
setups.
Operation of the TAS5600 is via
TASKIT/5600 control software.
Alternately, user-generated control code
can be employed via the TAS5600’s
comprehensive remote command set
over GPIB, Ethernet, or RS 232.
