Keithley Instruments - Press Release 6-17-2008
FOR IMMEDIATE RELEASE
Keithley's unique approach to instrument design provides simple,
low-cost upgrade path to future Wave 2 MIMO with 4x4 signal streams
and other new wireless standards
Keithley's RF test
solutions are based on the company's award-winning Model 2820 RF Vector
Signal Analyzers and Model 2920 RF Vector Signal Generators. Because
these test instruments rely on a next-generation DSP-based Software-Defined
Radio (SDR) architecture, they are capable of making extremely high
speed measurements both thoroughly and accurately. The SDR architecture
enables Keithley's highly flexible offering with instruments that are
easy and less costly to upgrade as new wireless and cellular standards
are introduced. In addition, the same Keithley signal analyzers
or signal generators can be used in an automated production environment
or can be moved easily to the bench for standalone test applications.
Keithley's test systems provide frequency
coverage from 400MHz to 4GHz and to 6GHz if WLAN measurements are needed.
Coverage in the lower frequencies, below 2.4GHz, has become more important
recently, as the 400-700MHz bands are being opened for new mobile wireless
communications services where WiMAX solutions are likely to be employed.
The Challenge of Next-Generation WiMAX
WiMAX is arguably the most complex modulation
scheme in the world, encompassing multiple technologies into one very
versatile system, including bandwidths in excess of 20MHz, configurations
with more than 2000 subcarriers, high peak-to-average power ratios,
and both SISO and MIMO radio configurations.
This complexity has made testing a challenge
for manufacturers. Keithley's Model 2820 RF Vector Signal Analyzer and
Model 2920 RF Vector Signal Generator enable users to test WiMAX in
any frequency band between 400MHz and 4GHz faster and more easily than
other available instruments.
A Powerful and Integrated WiMAX Solution
The Model 2820 RF Vector Signal Analyzer
is designed to work closely with Keithley's Model 2920 RF Vector Signal
Generator. Together, these two instrument families form a powerful
RF test and measurement solution that reduces test times and capital
equipment costs for testing RF devices. For example, production test
engineers can use built-in list mode features to perform fast simultaneous
measurement of components, transmitters and receivers - dramatically
reducing test times.
Working in conjunction with the two RF
test instrument families is Version 2.0 of Keithley's SignalMeister™
Waveform Creation Software, for creation of the entire range of signals
in accordance with WiMAX and WLAN wireless connectivity standards and
3GPP and 3GPP2 cellular standards. First introduced in mid-2007,
SignalMeister is a PC-based object-orientated waveform creation tool
that allows engineers to create highly complex signals required for
today's RF testing needs quickly and flawlessly. SignalMeister
is the only waveform creation software tool available that uses an object-oriented
graphical interface that is optimized for MIMO signals, allowing engineers
to easily create basic and complex waveforms.
SignalMeister is an expandable software
platform with a common user interface that allows creation of waveforms
from multiple signal standards with optional additive signal impairments
and channel modeling in a single environment. Users download the
waveforms they create to any Keithley Series 2900 RF Vector Signal Generator.
