RF analyser runs from the bench to the line
RF vector signal analyser is optimised for testing of wireless devices and transmitter circuits in production test environments, as well as new product research and development.
Keithley Instruments has released the Model 2810 RF vector signal analyser, optimised for automated testing of wireless devices and transmitter circuits in production test environments, as well as in new product and device research and development. It features measurement speeds up to three times faster than competitive instruments in production test, takes up half the space, and costs half as much as competitive products. The Model 2810 combines high performance, complex signal analysis capability with unprecedented ease of use for even those with little training, background, or practical experience in RF measurement to serve a wide range of measurement needs on wireless devices, transceiver modules, and RF components.
Keithley's Model 2810 is the lowest cost, widest signal acquisition bandwidth, stand-alone vector signal analyser with both manual and automated operation on the market today.
The Model 2810 RF vector signal analyser is designed to work closely with Keithley's Model 2910 RF vector signal generator.
Together, these two instruments form a powerful RF test ad measurement solution hat reduces test times and capital equipment costs for testing active and passive RF components.
For example, production test engineers can use built-in list mode features with the test modes of the latest mobile phone chipsets to perform fast simultaneous calibration of the phone's transmitters and receivers - dramatically reducing test times.
Mobile handset manufacturers and wireless component manufacturers are under tremendous pressure to reduce costs, address new technologies, and increase their manufacturing flexibility.
The Model 2810 reduces testing time with industry leading measurement and data acquisition times.
Keithley's Model 2810 vector signal analyser uses an advanced software-defined radio architecture with a 500MHz digital signal processor, enabling fast data acquisition and processing.
Production test engineers can drastically reduce test times, and R and D engineers and scientists can reduce the time it takes to acquire large sets of data.
For example, in the case of users searching for spurious emissions from devices under test, the Model 2810 can perform a 200MHz span sweep using a narrow resolution bandwidth of 100Hz in approximately 15 seconds.
A conventional spectrum analyser needs 1000 times longer to perform the same sweep.
Another factor contributing to the Model 2810's outstanding processing power is greater than 30MHz of 3dB measurement bandwidth with 20MHz of flatness within 1dB.
Wide bandwidth signals can be captured in one acquisition, which is essential for capturing the new high bandwidth, high throughput transmission signals such as WLAN and WiMAX signals.
This exceptionally wide signal acquisition bandwidth is much greater than conventional spectrum analysers and wider than most VSAs in the $30,000 and under price range.
The Model 2810 has the performance now to acquire the future 4G technology signals under development in R and D labs.
The Model 2810 is more than a spectrum analyser.
In addition to being able to decompose a waveform into its constituent frequencies, it can also decompose digitally modulated signals into their I and Q phase components.
With the I and Q components, a vector signal analyser can determine the quality of a modulated signal.
Research and development personnel working with modulation schemes can easily transfer the acquired signal components to a PC for more extensive analysis.
The Model 2810 offers firmware options at prices significantly lower than competitors to enable more cost effective modulation quality analysis on GSM and Edge signals, CDMA2000 Reverse Link signals, and WCDMA Uplink signals.
These measurements are performed much faster than analysers commonly used today.
A suite of GSM/EDGE measurements including time mask conformance, phase error or EVM, and channel power can be acquired and computed in 27ms.
This is twice as fast as the industry's current leading analysers.
The Model 2810's flexible, software-defined radio architecture gives telecom manufacturers the testing flexibility needed to keep pace with changing wireless technologies.
New modulation analysis schemes and new measurement algorithms can be incorporated easily and economically with ongoing firmware updates.
The Model 2810's upgradeability eliminates the need to buy another instrument when new measurement needs arise, making it a more flexible instrument over time and keeping down capital equipment costs.
In addition, with space at a premium, the Model 2810's reduced sise is a significant advantage, reducing the amount of space needed in a standard rack or on a benchtop.
The Model 2810 also speeds start-up and troubleshooting times in automated test development.
Its user-friendly interface also minimises the time it takes to learn how to operate the instrument.
In either R and D or university laboratories, even occasional users, such as RF development engineers and researchers, can quickly orient themselves to the nonintimidating front panel and easily make measurements.
The graphical user interface (GUI) greatly simplifies the use of such a complex instrument and eliminates the need for an entire front panel of buttons.
While typical spectrum analysers may have more than 20 buttons, the Model 2810 has only two buttons and an intuitive touch screen.
It can also be easily operated by a USB mouse, making it an excellent tool for communications theory training in student labs where PC-knowledgeable students can comfortably learn to make spectrum analysis measurements via the mouse.
The GUI uses a Windows-based display format, so any user who is familiar with operating a PC can easily navigate through the menus of the Model 2810.
A built-in help system makes all user information available at the touch of the screen or with the click of a mouse.
Because its GUI eliminates the need for a whole front panel of buttons, the Model 2810 can be packaged in an industry-leading half-rack package, saving precious rack space in production and R and D environments.
The Model 2810 includes a number of additional features that most competitive analysers do not provide as part of their standard offering.
Examples include electronic attenuation, pre-amplifiers, and a sweeping continuous wave source, all of which are included as standard features on the Model 2810 but are costly options on competitive instruments.
Also, an industry-leading three-year warranty on the Model 2810 is included at no additional charge.
The Model 2810 includes three standard interfaces to meet current and future system integration requirements.
An IEEE488 interface enables users of legacy systems to easily integrate the Model 2810 into their test systems.
Users looking for higher data transfer rates can use the USB or LAN interface.
The LAN interface is compatible with the new LXI standard.
Specifically, the Model 2810 conforms to the LXI-C standard.
The Model 2810 RF vector signal analyser is available four weeks after receipt of order.

Handheld tester hunts out rogue wireless devices
Fluke Networks has added new capabilities to its award-winning EtherScope Series II Network Assistant.
Fluke Networks has added new capabilities to its award-winning EtherScope Series II Network Assistant. The new security scan and locate features reduce the time to locate a rogue wireless local area network (WLAN) device by 75%, as measured by the time spent on the same task using an omnidirectional antenna found on most PC radio cards. The advanced WLAN locate feature uses an external, directional antenna to quickly identify and pinpoint the location of unauthorised wireless access points.
This includes access points in ceilings and on floors above and below, which saves time in a multi-floor environment.
Combined with the EtherScope's handheld, lightweight package and easy-to-read, colour touch-screen display, users will find rogue access points faster and easier than ever before.
Also new to EtherScope is the ability to test the performance of LAN and WAN links using commonly accepted RFC 2544 test procedures.
EtherScope Series II Network Assistant incorporates RFC 2544 tests for measuring throughput, latency and frame loss.
These tests are bundled together with EtherScope's current Internetwork Throughput Option and traffic generator.
Private network owners and service providers now have the ability to perform a fast, easy and RFC-based means of verifying network performance.
Carriers can document the performance levels delivered to their customers.
Private network owners can verify the bandwidth received matches that which was purchased.
Concurrent with the new RFC 2544 tests and advanced WLAN Locate ability, EtherScope will now support Russian as a user-selectable language.
EtherScope now displays its user interface, all desktop applications on the unit, report headers, and help screens in eight different languages (English, Chinese, French, German, Japanese, Portuguese, Spanish and Russian), making EtherScope Network Assistant a tool for the truly worldwide nature of networking.
EtherScope Series II Network Assistant is available for immediate delivery through Fluke Networks sales partners worldwide.
The RFC 2544/ITO tests and WLAN analysis, including the directional Locate feature, are available as options.
Current EtherScope owners can purchase these options as upgrades.

Supply sets standard for harmonics tests
Low-distortion AC power supply provides pure source of mains power for the measurement of current waveform harmonics as required for EMC compliance under EN61000-3-2.
TTi (Thurlby Thandar Instruments) has re-engineered its AC1000 low-distortion EN61000-3-2 compliant power source. The new unit, designated AC1000A, has been redesigned to improve both performance and ergonomics. The AC1000A is a 1kW low-distortion AC power supply designed to provide a pure source of mains power for the measurement of current waveform harmonics as required for EMC compliance under EN61000-3-2.
Compliance quality measurements under the standard require the source supply to provide a pure voltage waveform to the equipment under test.
The AC1000A is specifically designed for this purpose.
Many environments may have mains waveforms which diverge significantly from a pure sinusoid as a result of nonlinear loading, either within the environment or outside.
Most common of these distortions is the 'flat topped' waveform that results from high currents being taken at the voltage peaks.
The AC1000A is also very useful for the stress testing of power supplies in electronic equipment.
The use of a harmonically pure, distortion-free device is essential to fully stress and evaluate the power supply under test.
The power source is rated up to 1000VA for 230V operation.
It has a continuous current rating of 4.4A and a peak current rating of 10A.
In contrast to products which use a passive filtering approach, it uses an innovative technique which actively corrects the AC supply to produce a harmonically pure output.
The unit under test is connected via a standard 13A socket mounted on the front panel of the instrument.
Weighing only 5kg and measuring 307 x 105 x 225mm, the unit has a compact footprint which matches that of TTi's own power and harmonic analyser, the HA1600A.
