The Seattle weather was unexpectedly great for IMS2013, sunny and clear all week.  The venue was very good but the 2 room setup was far from ideal for the exhibition and some people did not even know there was a second room attached in the back left corner.  So it is not surprising that the traffic in the back room seemed to be a step below that in the front but still respectable. While the attendance did not seem overwhelming, there was some optimistic pockets of activity and many were satisfied with the high quality of the attendees.

Here a summary of the products from the exhibition for all of the companies our editors were able to visit during the event.

Test and Measurement:

Agilent Technologies demonstrated 25 of its newest design and measurement solutions, covering everything from circuit-level modeling through system verification for general RF, microwave, 4G communications and aerospace/defense. Areas covered included: design software, network analysis, signal generation and analysis, peak power analysis and AXIe digitizers.  They announced that its FieldFox handheld analyzers can now be remotely controlled via an iOS device such as an iPad or iPhone. Also new are a spectrum analysis time-gating option and support for Agilent’s USB peak-power sensors. These features provide engineers the precision and flexibility they need to more easily and quickly test their RF communications infrastructure.

They announced significant enhancements to their midrange N9020A MXA X-Series signal analyzer. New options for 160-MHz analysis bandwidth and real-time spectrum analyzer (RTSA) capability address the challenges of measuring interference in the next generation of heterogeneous wireless networks. The options can be included in new MXAs or added to existing units. The RTSA option is one-seventh the cost of a single-purpose real-time analyzer.

They also announced the E4980AL precision LCR meter with three cost-effective frequency options: 300 kHz, 500 kHz and 1 MHz. The new meter options are a follow-on to Agilent’s industry-standard E4980A LCR meter, which has long offered the best price/performance and application breadth among basic LCR meters.

Another announcement was there source/monitor unit (SMU) and software enhancements to its B1500A semiconductor device analyzer, the industry’s leading semiconductor parameter analyzer. The new B1514A 50-µs pulse medium-current SMU gives a faster pulse at 30V/1A range plus oscilloscope-like viewing. The new B1511B medium-power SMU delivers 0.1 fA low-current measurement capability at a lower price with an optional atto-sense switch unit. The latest EasyEXPERT 5.5 software enables remote test without complex programming, using more than 300 ready-to-use application tests in addition to manual operation.  You could probably spend a whole day at their booth (see software section also for more releases).

Anapico has extended the frequency range of a number of its products. The APSIN26G is a low-noise and fast-switching microwave signal generator covering a continuous frequency range from 100 kHz to 26 GHz. Advanced technology allows a 0.001 Hz frequency resolution, fast switching, excellent phase noise and a high power output. The signal generator operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) and can be phase-locked to any external reference from 1 to 250 MHz. Alternatively, the APSIN12G is a low-noise and fast-switching microwave signal generator covering a frequency range from 100 kHz up to 12 GHz and comprises a full set of analog modulation (AM, FM; PM, Pulse, Pulse trains, Chirps). Finally, the APSIN20G 5 MHz to 20 GHz signal source analyzer provides fast and accurate measurements of SSB phase noise and also provides full time domain analysis capability.

Anritsu displayed test solutions to meet the high-frequency testing requirements of engineers in the aerospace and defense, communications, and semiconductor industries. Center stage was the VectorStar Vector Network Analyzer (VNA) platform. For signal integrity engineers, the company showed the MS4640A series, which features wide frequency coverage of 70 kHz to 70 GHz, as well as high-accuracy time domain and wide dynamic range. There were also demonstrations of the ME7838A VectorStar 70 kHz to 110 GHz broadband VNA aimed at semiconductor test engineers who conduct on-wafer measurements, enabling them to see how the ME7838A achieves accurate, stable measurements over extended time periods.

For conducting pulse measurements in radar applications, Anritsu showed the MG3690C RF/microwave signal generators. Producing 100 ns leveled pulse widths with 10 ns resolution, as well as the ability to generate single, doublet, triplet and quadruplet pulses, the MG3690C features comprehensive emulation and testing of high-performance narrow pulse radars. The measurement side will be covered by the ML2495A Wideband Peak Power Meter, which is suitable for measuring fast radar pulses due to its 65 MHz video bandwidth.

Also on display was their Spectrum/Signal Analyzer, which was used to conduct millimeter wave measurements on a BridgeWave Communications 80 GHz Wireless Ethernet Bridge. It offers high dynamic range and low phase noise and supports direct coaxial input of signals up to 43 GHz. Maximum frequency may be extended up to 325 GHz via a range external harmonic mixers. A second test station demonstrated VCO analysis using the sophisticated signal analysis tools, which offers 14-bit resolution and a maximum analysis bandwidth of 125 MHz at frequencies up to 43 GHz.

AR has now complemented their previous line of 4-18 GHz Hybrid Power Modules (HPM’s) and bench top units with new designs to instantaneously cover the entire 0.7-6 GHz frequency range with one amplifier.  The 1-6 GHz modules have output powers up to 25 W Class A and 40 W Class AB, while bench top Class A units produce over 100 W.  Typical applications are EMC wireless testing and military EW.

dBm released their latest satellite link emulator providing a cost effective, time-saving, repeatable total test solution for satellite and aircraft RF link testing. They have various models, as an example the 1200 MHz center frequency emulator has a 1 dB bandwidth of 250 MHz and maximum delay per channel of 447 ms with up to 4 channels.

Empower RF continued to push the boundaries of minimizing real-estate among its high power amplifier platform. The companydemonstrated their 1 kW, 20 to 1000 MHz, 5U chassis design (model 2162). This air cooled chassis delivers over 1 kW of output power and is available in three specific models (in the frequency ranges of 20 to 500, 500 to 1000, and 20 to 1000 MHz). The company was also showing of the fully functional control software that allows users to operate the unit remotely using a standard web browser interface. With real-time monitoring and control, the software supports development of customized test sequencing for the unit to operate within a test lab system.

Holzworth Instrumentation’s phase noise analyzers were designed to optimize measurement speed and low noise floors, while being highly intuitive to set up and operate. In response to customer requests to measure both absolute and additive phase noise with Z540 traceability, Holzworth has released revision B of the HA7000 Series. The revisited design has a more advanced front-end, an external power supply for cleaner spurs (also allowing for powering the analyzer via a 12 V battery), and a Z540 traceable calibration. Most significantly, it has introduced fully automated additive phase noise measurements.

National Instruments was using LabVIEW system design software and high-performance modular hardware for solving design challenges with digital pre-distortion and envelope tracking measurements. In the DPD demo, AM-AM and AM-PM of the PA was measured.  The resulting information was used to create a lookup table to modify the waveform that was sent into the PA.  As a result, the PA performance was improved. In the ET demo, by modulating the Vcc signal in a manner that is synchronized with the RF signal generator, the PA operated at is most efficient region resulting in less power comsumption with less complexity and more precision using LabVIEW and the vector signal transceiver.

NI is building an ecosystem of partners to solve the challenge of load pull measurements.  These partners now include Anteverta, Cardiff/Mesuro, Maury and Focus which includes most of the experts in the field.

Harnessing the latest technologies is a key approach to graphical system design and involves FPGAs and CPUs.  Because of this, NI has found that PXI cna perform measurements at least 5 to 10 times faster than traditional rack-and-stack equipement.  Their PXI platform dramatically reduces test time in most situations.

Mesuro launched a new test solution that utilizes an ‘envelope load pull technique’, along with the latest generation of commercial off-the-shelf PXI hardware and LabVIEW system design software from National Instruments, to provide extremely rapid test scenarios to be run on the device under test. The ‘Rapid Load Pull’ product can replace traditional passive tuning networks within load pull test systems. The way in which the solution fits into the test environment allows for the existing measurement hardware to be re-used within the improved test station. The system can be supplied as a turnkey project to include, the NI portion with Mesuro Software/Coupler/Amplifier, etc or can be customer assembled. The system is currently available covering frequency ranges up to 4.4 GHz.

OML was showing of a number of new innovations including the mate-less waveguide connector that was featured as the cover story in MWJ’s February issue. Among the company’s new products, we were introduced to a 60 to 90 GHz VNA extender that provides single connection to the DUTs undergoing linear and nonlinear characterization such as S-parameter measurements, IMD and gain compression.

Rohde & Schwarz has added a realtime option and extended the frequency range of the R&S FSW high-end signal and spectrum analyzer. The new R&S FSW K160R option upgrades the R&S FSW to a realtime spectrum analyzer, giving users a single instrument that can be used for traditional spectrum analysis with excellent RF characteristics as well as spectrum analysis without any time gaps and a bandwidth of up to 160 MHz in realtime mode. With 600,000 FFT/s in realtime mode, the R&S FSW is claimed to have twice the time resolution of other instruments on the market and covers the entire frequency range from 2 Hz to 50 GHz.

The company also announced that it has doubled the analysis bandwidth of the R&S FSW signal and spectrum analyzer from 160 MHz to 320 MHz. The R&S FSW is currently the only signal and spectrum analyzer on the market able to process signals in this bandwidth.

Users who need to analyze radar signals with very short pulses of less than 10 ns or wideband signals in radar systems will find the analyzer to be the ideal tool. Analyzing automotive radar signals (FM CW radar or pulsed radar) requires at least 200 MHz, for example.

Rohde & Schwarz also presented the new midrange R&S ZNB20 and R&S ZNB40 vector network analyzers for frequency ranges from 100 kHz to 20 GHz and from 10 MHz to 40 GHz. These powerful analyzers are equipped with two test ports and offer outstanding measurement characteristics that are on a similar level as high-end instruments. A dynamic range of up to 135 dB makes the new instruments suitable for tasks such as performing measurements on high-blocking DUTs such as filters.

Tektronix and partner Octoscope demonstrated the use of an MDO4000 mixed domain oscilloscope to analyze 802.11g bursts, supporting the need for affordable signal quality testing for WLAN 802.11xx signals as Wi-Fi continues to gain speed and market acceptance. The MDO4000 is the world's first oscilloscope with a built-in spectrum analyzer, and another example of innovation from Tektronix.

Teseq showcased a number of products. To focus on just two, the first is the expansion of its broadband amplifier line to include the Class A linear and low distortion CBA 400M-260 model that operates from 10 kHz to 400 MHz with a rated power of 260 W. Used in commercial or in-house EMC test laboratories, the CBA 400M-260 is suitable for automotive, military and aerospace BCI (bulk current injections) applications that require testing at higher levels. Like other Teseq broadband amplifiers in its class, the CBA 400M-260 uses GaAs integrated circuit technology.

Now a part of Teseq, Milmega offers a new amplifier product range designed to meet test requirements within wireless testing frequency bands. The AS0728 family of amplifiers has a frequency range of 700 MHz to 2.8 GHz. Available in 25 W, 50 W, 100 W and 170 W P1 dB power levels, these amplifiers are ideal in the wireless communications industry where high reliability, excellent linearity, power density and leading performance are required.

Signal Generators through 20 GHz offer advanced features such as phase-continuous linear-frequency sweeping and optional pulse modulation. Eight new models to their LMS Series of Signal Generators have been added in the following bands: 70-450 MHz; 250-1500 MHz; 600-3200 MHz, and 1000-4000 MHz. Attenuators are easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. LDA Digital Attenuators are now available with popular N-Type Connectors and with input power up to 2 W. The new Lab Brick Solid State Switch product family features 10 W power handling capability and offers reliability and high isolation in both single pole double throw and single pole four throw configurations. And the Lab Brick Phase Shifter provides excellent phase accuracy while offering 1 degree phase resolution.

VDI was displaying their VNA extenders that provide high performance frequency extension of vector network analyzers into the THz range. Models are currently available for coverage from 50 to 1,100 GHz, with additional bands under development. These modules combine high test port power and excellent dynamic range. They are compatible with all modern network analyzers, and have been integrated with a variety of probe stations for on-wafer testing. Available options include increased test port power (selected bands), micrometer driven attenuators, reduced input frequency (24 or 20 GHz), increased cable length and waveguide based calibration kits.

Among their product demos, Wireless Telecom Group featured Current RF - a customer success story in their booth. Using WTG equipment, a successful test system was developed leading to results that show a reference design from Current RF (5mm x 5mm IC fabricated on an IBM process) will save anywhere from 10% to 20% of digital power in any given system with digital switching circuits(DSP).  In battery powered systems, potentially a 10% to 20% extension of battery life is possible. Battery size/weight reduction is made possible with the CC-100. In wall plugged systems, a 10% to 20% reduction in heat dissipation from power supplies is possible.


Agilent Technologies demonstrated 25 of its newest design and measurement solutions, covering everything from circuit-level modeling through system verification for general RF, microwave, 4G communications and aerospace/defense.  Its software highlights included the latest release of Electromagnetic Professional (EMPro), the company’s 3-D electromagnetic simulation software. EMPro 2013 allows engineers to simulate the radiated emissions of electronic circuits and components and then determine whether these emissions are within levels specified by common EMC standards, such as FCC Part 15, CISPR 22 and MIL-STD-461F. This capability is enabled by new specification-compliance templates, as well as several enhancements to both EMPro’s finite element method (FEM) and finite difference time domain (FDTD) simulators. EMPro 2013 will be available for download in July.

They announced two software releases that support the design and verification of envelope tracking, a technique that improves the efficiency and linearity of power amplifiers used in mobile handsets. New capabilities available in Agilent Signal Studio software and Agilent 89600 VSA software will help developers quickly optimize their envelope-tracking implementations. In Signal Studio for LTE/LTE-Advanced (FDD or TDD), developers can now define and optimize test stimuli for power amplifiers using envelope waveforms based on the LTE in-phase/quadrature (I/Q) signal. In addition, the crucial timing alignment between envelope and I/Q can be achieved with picosecond resolution and real-time adjustments. For playback during testing, Signal Studio can download the resulting waveforms to Agilent’s X-Series signal generators and 33500 Series waveform generators.

Agilent Technologies also introduced the latest addition to its repeater model library for quickly and accurately solving the challenge posed by signal distortion in the multigigabit-per-second regime. The retimer solution, available in the Advanced Design System 2013 Transient Convolution Element and SystemVue 2013 AMI Modeling Kit, is used for designing electrical retimers in chip-to-chip, high-speed digital links.

Phase Matrix QuickSyn® microwave synthesizers deliver instrument-grade performance, increased functionality, and efficient power consumption at a reduced size and low cost. The synthesizers employ a patented, revolutionary phase-refining technology that provides a unique combination of fast-switching speed and low phase-noise characteristics. They utilize a fundamental VCO to achieve the desired output frequency. In contrast to frequency multiplication schemes, this approach eliminates possible spectrum contamination from subharmonic products. The use of the advanced direct digital synthesis approach, enables a very fine frequency resolution of 0.001 Hz. The VCO noise is suppressed by utilizing an ultra low noise reference oscillator in conjunction with a low-noise locking mechanism. Microphonic effects are also greatly reduced due to the use of a low-mass VCO and very wide PLL filter bandwidth. They are not offered in a significantly reduced size form factor.
