Equally impressive is the number of new product releases announced every year at IMS.
The company introduced five new PNA microwave vector network analyzer models based on Agilent’s PNA-X architecture. The PNA family includes the PNA-L, PNA and PNA-X Series, covering frequencies from 300 kHz to 1.05 THz. The PNA-L is designed for general-purpose network analysis; the PNA is the company’s high performance vector network analyzer available with two-port internal single-source or four-port internal dual-source configuration in five frequency models: 13.5, 26.5, 43.5, 50 and 67 GHz, high source output power of +11 dBm at 67 GHz ( N5227A 67 GHz model) and a 0.1 dB receiver compression point higher than +10 dBm (all models). Meanwhile, the PNA-X provides complete linear and nonlinear component characterization in a single instrument with a single connection and can perform noise figure measurements, gain compression, two-tone IMD/spectrum analysis, true-mode stimulus, source phase control and fast CW mode.
In addition to the PNA series, the company introduced its ENA Series of network analyzers, the E5072A vector network analyzer, available as either a two-port, 30-kHz to 4.5-GHz or 8.5-GHz instrument. The E5072A, available with a sweep time of 4 ms with 401 points, is designed for cost-sensitive manufacturing customers requiring higher performance than comparably priced RF network analyzers, addressing this need with enhanced capability and performance at an affordable cost.
Agilent has also entered the peak power test equipment market with the introduction of its 8990B analyzer for the aerospace, defense and wireless markets. Combined with either the new N1923A or N1924A wideband power sensors, which cover a frequency range of 50 MHz to 18 GHz and 50 MHz to 40 GHz, respectively, the 8990B peak power analyzer achieves 5 nanosecond rise time/fall time, the fastest overall rise time/fall time in the peak-power market.
For testing radar and EW systems, the company introduced N7620A Signal Studio for pulse building software enables the creation of highly realistic test signals. New options add the generation of pulse-width and pulse-repetition interval patterns, which enhance the realism of radar simulations. Impairments such as jitter and wobulation add even greater realism to simulated pulsed-RF signals. Options include a wide variety of antenna scan and radiation patterns, enabling accurate modeling of antenna behavior. Signals created with Signal Studio for pulse building can be downloaded into instruments such as the Agilent E8267D PSG vector signal generator. A recent enhancement to the PSG, Option UNY, typically provides -143 dBc/Hz phase noise (10-kHz offset, 1-GHz signal), which is required for precise simulation of moving-target-indicator (MTI) and pulsed-Doppler radar signals.
On the software side, the folks at Agilent EEsof EDA introduced a new Eigenmode solver to their EMPro product as well as cut-planes in the 3D modeler that allows the user to view internal details of complex structures and easily snap to internal objects. Animated electromagnetic field visualization enhancements provide improved design insight while the Eigenmode solver helps designers quickly find the resonant frequencies for RF structures such as cavity filters. EMPro is integrated with the company’s popular ADS RF/microwave circuit design environment. See our 4 video demos from the show of Agilent products.
Anritsu was featuring a number of test solutions in their booth including a new Jitter modulation source and the MP1825A 4 Tap Emphasis converter, which were designed for integration with the MP1800 Signal Quality Analyzer. The configuration supports jitter tolerance and generates emphasis signals up to 28 Gbit/s for evaluation of high-speed interconnects common to PCBs found in digital transmission equipment and computer backplanes.
A test instrument that may be more familiar to the microwave community, was the new ME7838A broadband vector network analyzer (VNA) system introduced by Anritsu. This impressive broadband VNA provides single-sweep coverage from 70 kHz to 110 GHz with operation from 40 kHz to 125 GHz, and utilizes an advanced design that eliminates the need for large, heavy millimeter wave (mmWave) modules and coax combiners. Most test engineers taking S-parameter at mmwave frequencies are very familiar with the large and cumbersome external modules that extend standard microwave VNAs for use at these higher frequencies. Besides for consuming considerable bench space, these frequency extenders make it difficult to apply signals directly to die on wafers without the use of performance hindering coax cables. The ME7838A provides broadband device characterization of active and passive MW/mmWave devices, including those designed into emerging 60 GHz wireless personal area networks, 40 Gbps and higher optical networks, 77 and 94 GHz automotive radar, digital radio links, 94 GHz imaging mmWave radar, and Ka-Band satellite communications. See of video demo of the new Anritsu VNA.
ANSYS, which acquired Ansoft several years ago, was on hand to introduce a new finite array analysis with domain decomposition to its HFSS product, a leading industry tool for 3D EM simulation. This HPC parallel computing technique leverages the breakthrough domain decomposition solver to efficiently set up and analyze large, finite sized antenna arrays. The user simply draws the unit cell geometry of a repeating array element, then defines the size and shape of the array, solution setup and solves. Efficiencies in solution are realized through parallel computing on one or more networked machines. The solution captures the effects of finite sized array such as edge effects for radiation patterns and coupling matrices. In general any repeating design such as photonic band-gap structures frequency selective surfaces or even multi-wafer backplane connectors can take advantage of this technique for efficient computing of finite sized geometrically repeating structures.
The company was also demoing Solver on Demand in Designer RF, which provides a layout driven or “electrical CAD” flow for the rigorous solution from HFSS. This interface provides for many engineers an intuitive and easy to use entry point for HFSS. Many aspects of the simulation process are greatly simplified allowing for faster and more automated setup for simulation saving valuable engineering time and money. In addition this interface provides a closer link to many of the more common EDA design tools along with a more generic interface for the industry standard ODB++ format. Built in the Designer RF layout interface it provides a very tight link between rigorous full wave electromagnetics from HFSS and circuit/system analysis.
AWR apart from the big news of their acquisition by National Instruments, was very eager to display the latest product enhancements and features to the Microwave office, VSS, ACE, AXIEM and Analog Office products. The big push was to introduce show attendees to the company’s enhancements for Design sharing (group design), which targets the needs of enterprise-level design activity among global engineering organizations. The new features make it easier to manage data (schematics, layout, EM analysis and measurements) and resolve conflicts as sub-designs are shared and combined into modules or sub-systems by collaborating design groups. Other new features include simulation state management (allows large amounts of simulation results, optimization and Monte Carlo analyses to be managed by MWO, AO and AXIEM), enhanced yield analysis, RF aware short/open connection checker, and floating windows that can be pulled outside the run-time window for analysis. See of exclusive video interview with the CEOs of NI and AWR.
