Keithley's WiMAX solution is built on a next-generation hardware platform
that enables the simple and inexpensive addition of support for new
signal standards and methodologies (such as 802.16e mobile WiMAX Wave
2 testing of up to 8x8 MIMO channels) without requiring users to purchase
expensive hardware upgrades or new instrumentation. Keithley MIMO systems
based on the Keithley Model 2820 RF Vector Signal Analyzer and Model
2920 RF Vector Signal Generator offer unprecedented time and phase synchronization
of MIMO signals. For example, such a system can accommodate the
generation of MIMO signals with under 1ns of timing alignment and less
than 0.1º of phase jitter. Similarly, the system's multiple Model 2820
analyzers can acquire signals synchronized to fewer than 250ps of time
record jitter. Keithley leads the market in offering innovative MIMO
test solutions that provide a tightly integrated hardware and software
solution for 802.11n WLAN and 802.16 Wave 2 devices.
"WiMAX is quite possibly the most complex
modulation scheme in the world, encompassing multiple technologies,
and this complexity has made testing a challenge for manufacturers,"
said Mark Hoersten, vice-president of business development for Keithley.
"Keithley's WiMAX test solution will enable Fujitsu Microelectronics
to test in any frequency band between 400MHz and 6GHz faster and more
easily than any competing offering.
"Keithley has demonstrated a solid understanding
of our WiMAX testing application and requirements," said Makoto Awaga,
general manager of the Mobile Solution Division at Fujitsu Microelectronics
Limited. "They have provided us with a powerful and integrated WiMAX
solution that makes very high-speed measurements at the high accuracy
levels that are beneficial to production testing."
Keithley's Series 2800 RF Vector Signal
Analyzers and Series 2900 RF Vector Generators, which are designed to
meet the challenges faced by designers and manufacturers of today's
wireless technologies, are also suitable for emerging and future technologies.
Because these test instruments are based on next-generation DSP-based
Software-Defined Radio (SDR) architecture, they are capable of making
extremely high speed measurements with excellent accuracy. Their SDR
architecture also enables easier and less costly instrument upgrades
to accommodate new wireless and cellular standards. In addition, 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. Coverage in the lower frequencies (below
2.4GHz) is gaining in importance, as the 400-700MHz bands are opened
to new mobile wireless communications services likely to employ WiMAX.
