Using Calibration to Optimize Performance in Crucial Measurements
As we referred to "Please Come to Boston in the Springtime" as our pre-show theme song, we are making "Rock Lobster" by the B-52s our post-show theme song. IMS2009 probably faced some of the biggest challenges in its history--a big economic downturn and the swine flu virus, for example--but everyone pulled together and rocked in Boston with a successful show. The show attendance for the technical conference and exhibition turned out pretty well after some initial pre-show concerns.
Based on initial registration data for IMS2009 that took place June 7-12 in Boston, technical registration was 2,676, an 11 percent increase over 2008 registration and exhibit-only registration numbers indicate 2,131 participants, an 83 percent increase over 2008. IMS2009 attracted 559 exhibiting companies, also an 11 percent increase over the number of exhibitors in 2008. According to preliminary results, the total number of IMS2009 participants, including exhibitor booth staff and guests, was 9,316 attendees, an 11 percent increase over 2008 participation.
The plenary session with Petteri Alinikula of Nokia drew a large crowd and the technical sessions were well attended. There seemed to be good advances in amplifier and nonlinear characterization along with other areas. LDMOS and GaN are really fighting it out for the very high power applications with SiC and other vertical FETs making some noise. See our June issue cover story for more details.
Congratulations to Fred Schindler - IMS 2009 Chair, Tina Quach - RFIC 2009 Chair and Charles Wilker - ARFTG 2009 Chair and their teams for running successful conferences. Several of us at Microwave Journal were on Fred's team, so we are well aware of the hard work everyone puts into these conferences and exhibitions. It was a pleasure working with Fred as he was very organized and had an experienced team in place. You can view our video interview with him during the show at here.
With over 550 companies exhibiting new products and capabilities, Microwave Journal editors had a lot of ground to cover, from the show floor to organized press conferences. Below is a summary of the companies and products we came across.
Anritsu Co. introduced several new products at IMS 2009 including the MA24108A/MA24118A microwave USB power sensors that provide accurate average power measurements from 10 MHz to 18 GHz over 60 dB of dynamic range. Employing a “dual path” architecture to achieve True-RMS measurement similar to a thermal sensor over the entire frequency and dynamic range, the power sensors can measure CW, multi-tone, and digitally modulated signals used in commercial and aerospace/defense systems.
Anritsu also introduced the MN469xA series 4-port test sets for use with its VectorStar MS4640A vector network analyzer (VNA). The development of the MN469xA series takes advantage of VectorStar’s 70 GHz high-performance, proven switching technology to produce the high accuracy and wide dynamic range necessary to conduct 16 fully corrected S-parameter measurements with speed and accuracy.
And finally Anritsu introduced the VectorStar™ Broadband ME7828A vector network analyzer system that produces industry-best dynamic range, measurement speed, and calibration and measurement stability over the broadest frequency range of 70 kHz to 110 GHz. The performance and frequency coverage provide designers and manufacturers of microwave/millimeter-wave components and devices with a single system to accurately and quickly measure devices from DC to daylight.
Agilent Technologies was a dominant force at the show with a large booth front and center, press conferences and talks, platinum show sponsorship and expanded MicroApps area that they sponsored and organized. They introduced a Microwave Signal Generator that breaks the one-watt output power barrier: The Agilent PSG E8257D option 521 signal generator delivers output power in excess of one-watt over most of its frequency range. With specified output power from +24 to +28 dBm over most of its 20 GHz of frequency range, it eliminates the need for additional hardware such as amplifiers, couplers and detectors in most high-power test environments.
They also recently announced Advanced Design System (ADS) 2009 Update 1, the industry's first complete, front-to-back solution for monolithic microwave integrated circuit (MMIC) and RF module design. The release integrates 3-D electromagnetic (EM) analysis, wireless standards-based design verification libraries, X-parameter simulation, and statistical design and yield optimization. Advanced Design System 2009 Update 1 enables designers to stay within the design and simulation platform of choice for their entire design cycle and eliminates the need for separate, time-consuming point tools.
Also the Advanced Wideband Vector Signal Analysis and Digital Troubleshooting: Agilent's Infiniium 9000 Series oscilloscopes offer the broadest measurement capability with true analog bandwidths up to 4 GHz. They have impressive scope performance and built-in logic and protocol analysis. These oscilloscopes are the world's first scopes with integrated logic analysis channels and a protocol analyzer viewer for buses such as PCIeTM and USB. These integrated features extend scope functionality, making it easier for engineers to test complex designs, and giving companies higher oscilloscope utilization for better return on capital equipment.
Agilent Technologies expanded its mixed-signal and digital-storage oscilloscope portfolio with six new models that comprise its next-generation Infiniium 9000 Series. These scopes offer the broadest measurement capability with true analog bandwidths up to 4 GHz, impressive scope performance, and built-in logic and protocol analysis. Each model, equipped with the industry's largest screen -- a 15-inch (38.1 cm) XGA LCD display -- comes in a highly portable package that is just 9 inches (22.86 cm) deep and weighs only 25 pounds (11.3 kg).
Agilent Technologies announced that SATA-IO has certified the Agilent SATA total test solution, which is used by Allion Test Labs. The test platform includes a transmitter, receiver and test automatic software platform. The Serial ATA International Organization (SATA-IO) develops, manages and drives adoption of the Serial ATA specifications. The SATA interface is the industry-standard application used to manage data transmission between system board and storage device on personal computers, laptops or server systems. SATA Gen 3 can drive speeds up to 6 Gbps.
And finally a significant announcement in that they recently expanded the flexible PNA-X network analyzer with 13.5, 43.5 and 50 GHz models. The 43.5 and 50 GHz models support higher frequency applications such as radar and satellite communications, while the 13.5 GHz model is ideal for lower-frequency devices used in wireless communications. Agilent's PNA-X nonlinear vector network analyzer (NVNA) has also been expanded to include a 13.5 GHz model and the industry's first 43.5 and 50 GHz NVNA. These new solutions provide engineers developing and manufacturing active devices the flexibility to select just the right frequency that is required for their specific application.
Tektronix displayed the recently introduced Option 200, for the RSA6000 Series spectrum analyzer. Innovative DPX Density™ triggering enables another unique method of isolating frequency domain signals based on statistical occurrence. The swept DPX functionality enables DPX spectrum viewing over the entire range of the spectrum analyzer, to 14 GHz, and the highest probability of detecting spectrum events. With >292,000 spectrum updates per second, the patented DPX technology represents a six-fold improvement on the first generation capability.
The RSA6000 Series spectrum analyzer with option 21 now includes new modulation analysis and display enhancements for the government communications designer and operators of spectrum management systems. The new modulation types enable development of cutting-edge communications systems necessary to meet the need for increased communications bandwidth and spectrum efficiency in military and homeland security applications.
Tektronix has teamed with Mesuro Limited to demonstrate the most advanced system for nonlinear measurements that is commercially available. Based on the Tektronix AWG7122B Arbitrary Waveform Generator and DSA8200 Sampling Oscilloscope, the Mesuro MB 20 Open Loop Active Harmonic Load Pull system enables the characterization of devices and power amplifiers for any signal and impedance environment up to 150 W in power. Being an all-electronic solution, it is ideal for on-wafer measurements. These solutions enable customers to design more efficient power devices for the wireless industry and have a demonstrated capability to optimize performance with first-pass designs. The system was shown in the Tektronix booth #2624 at IMS2009. Microwave Journal moderated a Webinar on the subject which can be viewed here.
Tektronix had new enhancements to improve the utility of its portable spectrum analyzers for remote RF monitoring and sensing applications. Users are able to improve spectrum awareness for unattended applications with synchronous triggering and GPS time stamps for RF measurements.
Tektronix also introduced a new software module for RFXpress (RFX100 option SPARA) that provides emulation of RF components from touchstone files. Engineers can use arbitrary waveform signals and cascade multiple touchstone files to emulate a RF chain gain insight into component behaviour with a complex stimulus and to shorten design time. The effect of the RF component can also be de-embedded by selecting the Inversion option.
Rohde & Schwarz and Noisecom have jointly set up a test solution for making Y-factor noise figure measurements in the 60 GHz frequency range. The system, which is much less complex than traditional noise figure measurement systems and does not require downconversion using harmonic mixers, was demonstrated at the Rohde & Schwarz booth.
Rohde & Schwarz demonstrated a complete system for generating and analyzing user-defined and standard independent Orthogonal Frequency Division Multiplex (OFDM) signals at its booth at the show. The system consists of R&S signal generators and a signal analyzer using OFDM specific measurement software and covers microwave frequencies up to 40 GHz with a signal bandwidth up to 100 MHz.
Rohde & Schwarz also demonstrated a new technique for measuring the group delay of frequency-converting devices at the show. The technique does not require access to the local oscillator (LO) of the device under test. This is extremely useful in applications such as satellite communication links and highly-integrated devices in which the LO cannot be accessed. The solution is extremely fast, accurate and easy to use. It is available as an option for all four-port R&S ZVA and R&S ZVT Series of vector network analyzers.
In addition, Rohde & Schwarz demonstrated new capabilities for evaluating differential (balanced) devices at the International Microwave Symposium. Rohde & Schwarz R&S ZVA and R&S ZVT series of vector network analyzers (VNA) equipped with the R&S ZVA-K6 true differential option can now take advantage of the coherent signal sources to adjust them to a selected phase or amplitude offset. This unique capability, made possible by a special architecture, is valuable when characterizing phased-array antennas, the nonlinear behavior of differential amplifiers and many other applications for aerospace and defense.
Keithley Instruments Inc. announced that it has upgraded its popular RF Vector Signal Analyzer line with new capabilities that reduce signal acquisition and measurement times. The new Model 2820A RF Vector Signal Analyzer, which provides a 40 MHz signal acquisition bandwidth with a frequency range of either 400 MHz to 4 GHz or 400 MHz to 6 GHz, builds on the capabilities of Keithley’s Series 2800 signal analyzer line. It expands the line’s applications for testing wireless devices to today’s high throughput, complex modulation, and wide bandwidth wireless telecom standards.
Keithley also introduced the Model 2891-IQ Upconverter, which provides comprehensive support for transceiver testing by processing analog I and Q baseband signals for testing a transceiver’s transmitter, as well as processing analog I and Q output signals for testing a transceiver’s receiver.
AWR announced AWR Connected for Rohde & Schwarz, which integrates the capabilities of R&S WinIQSIM2 simulation software from the leading test and measurement manufacturer within its Visual System Simulator (VSS) system analysis software. The complete range of digitally-modulated signals generated by R&S WinIQSIM2, along with those already present within VSS, ensure that the same real-world test signals can be used throughout the design cycle.
Mimix Broadband develops state-of-the-art GaAs semiconductors for RF, microwave and millimeter-wave applications in the telecommunications, satellite communications, and defense markets. Mimix Broadband was designing a millimeter-wave converter that employed innovative passive circuits. If the design could be realized successfully, it would achieve exceptionally high performance without using larger conventional millimeter-wave wave structures that would result in a larger die size and greater cost. However, this required the entire structure to be solved in order to verify the design.
Using a variety of commercial electromagnetic (EM) solvers, Mimix Broadband was unable to simulate the entire monolithic microwave integrated circuit (MMIC), which includes more than 100 ports and 100,000 unknowns. The company’s designers turned to AWR’s AXIEM software, which solved the entire structure on a desktop PC. Armed with a full-chip EM solution, Mimix Broadband had far greater understanding of the circuit’s physics as well. The complete story detailing Mimix Broadband’s design challenge is available at www.awr.com.

Boonton, a Wireless Telecom Group Co., introduced a new, very fast 59318 Peak Power Sensor that is optimized for Boonton’s 4540 and 4500B Peak Power Meter product lines.
Wireless communication and aerospace technology is getting increasingly complex. Highly dynamic signals with noise like signal characteristics, fast switching carriers, as well as pulsed signals need to be measured and analyzed. Developers and engineers need measurement tools that allow them to tackle such intricate waveforms. Boonton proudly announces a new RF Power Sensor that fulfills these requirements – the 59318. The dynamic input power ranges from -24 to +20 dBm in Peak mode and -34 to +20 dBm in CW mode, with input frequencies of up to 18 GHz. With its very fast rise time of <10 ns and a bandwidth of 50 MHz, the new 59318 can handle the most difficult signal forms. Due to its high speed the sensor is likewise ideal for statistical measurements. These are utilized if signals show noise like characteristics; hence do not support conventional trigger methods. The 59318 is extraordinary fast but also able to handle very low frequencies, starting already as low as 50 MHz. Frequency range is dependent upon which bandwidth the sensor is set to; it ranges from 0.5 to 18 GHz in high bandwidth mode and from 50 MHz to 18 GHz in low bandwidth mode. All 59310 sensors are equipped with an N (m) connector.
