KEITHLEY ADDS NEW CAPABILITIES AND MEMORY ENHANCEMENTS TO MODEL 2910
RF VECTOR SIGNAL GENERATOR
Ohio – June 5, 2007 -
Inc. (NYSE:KEI), a leader in solutions for emerging measurement
needs, announces a series of enhancements to its
Model 2910 RF Vector Signal Generator. The new capabilities included
in the Model 2910 V2.0 include additional wireless signal generation
waveforms, a new power calibration feature, and increased ARB memory
to accommodate more and larger waveforms. To learn more about Keithley’s
Model 2910 V2.0 RF Vector Signal Generator, visit
award-winning Model 2910 RF Vector Signal Generator has been recognized
for a number of industry innovations, such as its Software-Defined Radio
(SDR) Architecture, patent-pending synthesizer technology, and unique
power leveling circuitry. The Model 2910 uses a highly versatile software
architecture to adapt to the quickly changing test requirements of the
dynamic wireless market. It provides a flexible RF test platform that
reduces test times with fast frequency tuning, amplitude settling, and
waveform switching for half the cost of instruments with similar, or
less, performance capabilities. The Model 2910 can internally generate
virtually any signal with up to 40MHz of modulation bandwidth and signals
greater than 400MHz modulation bandwidth using external I-Q inputs.
The Model 2910’s continuous tuning capability from 400MHz to 2.5GHz
covers the key ISM bands used for wireless communications.
addition, the Model 2910 has the most intuitive user interface on the
market, making it simple for even the novice user to quickly and easily
generate RF signals. With an unrivaled combination of high accuracy
and repeatability, speed, flexibility, ease of use, and compact size,
the Model 2910 V2.0 employs new approaches to RF test and measurement
that enables users to get accurate measurement results quickly, reduce
test times, and decrease costs.
Powerful New Modulation
The Model 2910 V2.0 features two new modulation
capability options. The first of these, the Model 2910-DIG, is a flexible
digital modulation option that allows users to create an extensive range
of signal modulations used in modern RF communication products. The
Model 2910-DIG lets users create multiple permutations of all digital
modulation signals including ASK, FSK, PSK, and QAM, each with user-selectable
symbol rates, filter types, and data types. The Model 2910-DIG option
is especially useful in research and development labs and in education
for its ability to easily create a wide range of digital modulation
The other new option is the Model 2910-GPS, a low-cost
and flexible solution for GPS testing that is especially well suited
for production test environments. The Model 2910-GPS option simulates
the coded L1 signal of a GPS satellite with a variety of data types,
including using an external user-file with up to 37,504 bits (12.5 minutes)
of actual satellite data. Comparable solutions cost at least twice as
much as the Model 2910 V2.0 with GPS option. Together with other common
wireless standards, such as GSM, EDGE, W-CDMA, cdmaOne, and cdma2000,
the Model 2910-GPS option expands the scope of the Model 2910’s RF test
and measurement capabilities to test mobile devices with integrated
Improved Power Calibration Increases
Keithley’s Model 2910 V2.0 also features a
new power calibration table that improves measurement accuracy by compensating
for RF power losses in test fixture cables. The table stores power vs.
frequency values of the cables obtained via a separate RF power meter.
The Model 2910 then automatically adjusts the power, correcting for
cable losses to an accuracy of +0.3dB. This reduces operator error when
making manual measurements and eliminates the need to develop power
correction programming scripts in the test executive for automated systems.
Calibrating the test fixture is simplified with a new SCPI (Standard
Commands for Programmable Instruments) command feature that allows an
external PC connected to a Model 2910 V2.0 to control a separate RF
power meter, such as a handheld Keithley Model 3500 RF Power Meter,
via a USB cable; the power meter is used to measure power at the RF
cable connected to the device under test. Compensating for cable power
loss is critical for production test environments to reduce measurement
uncertainty, which helps to increase product quality and yields.
Increased Memory Supports Large Waveforms
Another enhancement to the Model 2910 V2.0 is its Arbitrary Waveform
Generator (ARB) memory expansion to 100 Mega-samples, allowing very
large waveforms or many smaller waveforms to be loaded into memory.
The 100 Mega-sample ARB of the Model 2910-ARB option supports multiple
signal waveforms to be resident in memory and enables switching between
these waveforms in less than three milliseconds using a remote-control
SCPI command over the instrument’s GPIB, USB or LAN interfaces.
A new ARB Sequencing feature further speeds up waveform switching
times to support instant transition times. Here, the waveform sampler
moves from the last point of an ARB waveform to the first point of the
next waveform in one clock cycle. The ARB waveforms can be played in
any sequence, providing added flexibility for speeding up measurements.
Such fast and flexible testing is especially useful for production test
Whether switching between frequencies, amplitude
levels, or waveforms, the Model 2910 V2.0 delivers measurement speeds
that are two to twenty times faster than traditional instruments – delivering
the fastest execution times for testing wireless devices and products.
Preserving Capital Investment
Model 2910 V2.0 RF Vector Signal Generator is an extremely accurate
and versatile test instrument. It is readily adaptable to new wireless
standards, increasing productivity, reducing time to market, and protecting
test equipment capital investment. Users can easily upgrade to new and
emerging standards as they become available without expensive hardware
upgrades or new equipment purchases. The Model 2910 is a flexible RF
test platform with the performance needed for today and the flexibility
for the test needs of future RF wireless technologies.
owners of the Model 2910 can download the Model 2910 V2.0 firmware with
standard enhancements from Keithley’s Web site at no additional cost.
Units can also be upgraded with the optional Model 2910-DIG or Model
2910-GPS, or both. These can all be done in the field, do not need to
be returned to a Keithley Service Center, and require no hardware upgrade.
Price and availability: Units are now available
with four weeks delivery. The base price for the Model 2910 V2.0 RF
Vector Signal Generator is $13,400 USD. The ARB option is $3,150 USD,
the flexible digital modulation option is $3,500 USD, and the GPS option
is $2,500 USD. Firmware upgrade is free for existing owners of Model

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
