Copyright © 2011 Agilent Technologies Modular Solution Space 7 A/D Industry -In 2004 the US Department of Defense (DoD) announced its business and technical strategy to adopt an Modular Open Systems Approach (MOSA) for developing new systems or modernizing existing ones. Here is a sample of the MOSA objectives taken from the Executive summary. The document further states that these edicts will be followed, where feasible. o Adapt to evolving requirements and threats o Leverage commercial investment o Reduce the development cycle time and total life-cycle cost o Enhance commonality and re-use of components among systems o Enhance access to cutting edge technologies and products from multiple suppliers o Mitigate the risks associated with technology obsolescence o Mitigate the risks of a single source of supply over the life of a system o Enhance life-cycle supportability
Copyright © 2011 Agilent Technologies Modular Value 8 Modular hardware need to be designed from the perspective of breaking down the block diagram of an existing system. A complete VSA might become an attenuator / preselector module, a downconverter (perhaps both Rf & uW), an LO module and a Digitizer module. A serious attempt should be made to allow maximum re-use of these modules. In this way an LO designed for a VSA can be re-used in a VSG New Technology needs to be made available in module form as soon as possible. Customers will find a way to utilize the module if it confers enough advantage over the existing technology to make it worth the effort. Incremental improvements to system modules are acceptable Improving the performance of just one module can make for a much better system. For example Improving LO phase noise in a module will improve overall VSA specs

Copyright © 2011 Agilent Technologies Generation of Typical Wideband Measurements 14 Signal Simulation Designing Waveforms When creating waveforms for the Agilent M9330A 1.25G Sa/s 15bit QARB a broad set of applications are used. These include Signal Studio, Agilent SystemVue and MATLAB. Each having its own benefits. Wideband RF Measurements Up-converting baseband IQ waveforms The Agilent M9330A QARB is limited to generating a waveform at a bandwidth within its Nyquist sample rate. Upconverting radar waveforms to microwave carriers can be accomplished using the Agilent PSG (E8267D) and Option 016 – which adds wideband IQ Inputs

Copyright © 2011 Agilent Technologies Wideband Modular Solution Space 16 Industry trends in general predicts movement of some business from traditional box instruments to modular Particularly acute for manufacturing test systems High Speed - modules are an extension of the pc backplane Inherent Upgrade Opportunities Means longer useful service life since single modules upgrades can match test requirements. Reduced cost of ownership since complete system does not need to be replaced. Flexibility - Multi-vendor mix match capability and system re-configurability Replace Rack & Stack – reduced footprint Agilent modular products can directly leverage our industry leading measurement science (89601 VSA SW for example) – this measurement capability is severely lacking in competitive modular solutions.
Copyright © 2011 Agilent Technologies Modular Value (A Software Perspective) 17 Modular systems use a defined software standard for instrument control and can provide support for multiple programming environments. –IVI-COM and IVI-C –LabVIEW, MATLAB,.NET, and C++ leverage the IVI Modular systems should provide a consistent look and feel across all modules or defined modular systems –Each module has a software front panel control for manual setup and diagnostic support –A test developer experienced on one set of modules already has the software programming skill to move to another set of modules A modular system should allow for the coordination and control of multiple sub-systems –A modular system should allow the overlap of setup and acquisition of different instruments or sub-systems to minimize test times

Copyright © 2011 Agilent Technologies 29 Flexible, Scalable and Upgradeable Solutions Flexible Being able to serve multiple needs and is easily reconfigurable Agilent VSA software can exist as a Digitizer only Much of the VSA hardware could be leveraged into a VNA product Scalable Being able to coordinate multiple instances of a measurement or sub-system The Agilent M9210A digitizers can be synchronized in to within one sample by using the concept of an ASBus. The ASBus connects the ADC sample clocks across multiple modules via a simple front panel adaptor Upgradeable Being able to easily improve functionality or performance by replacing discrete modular components [includes customizable FPGA] Improving system performance by replacing individual modules
Copyright © 2011 Agilent Technologies In Summary 30 Modular products provide an level of flexibility and an upgrade path that traditional box instruments typically cannot approach Many manufacturing customers are migrating to modular-style instruments for improvements in speed and the reduced footprint. Other customers are migrating because to them Modular just makes more sense (The DoDs move to MOSA being a case in point) It is likely that Modular products will have a longer useful service life because individual modules can be upgraded to improve system performance over the service life of the instrument. If the Modular paradigm is proving attractive on these grounds alone, then it must seem more compelling still as Agilent brings its industry recognized Measurement science over to its modular products
