RF & Wireless Test & Measurement Agilent Technologies Celebrates Third Anniversary of InfiniiVision X-Series Oscilloscopes Agilent Technologies Inc. is celebrating the third anniversary of its InfiniiVision X-Series oscilloscopes, which redefined oscilloscope technology with several innovations: The InfiniiVision X-Series’ success has propelled Agilent to be the fastest-growing oscilloscope company in the world for the past several years, as demonstrated most recently by the 2013 Global Oscilloscopes Growth Leadership Award from Frost & Sullivan. Agilent is celebrating the X-Series anniversary by offering a powerful new investment-protection program called “Upgrade to Your Ultimate Scope.” With this promotion, users can turn on all software applications on their X-Series oscilloscopes instantly, including the arbitrary waveform generator and digital voltmeter. The promotion can be used in conjunction with Agilent’s “Supercharge Your Bandwidth” promotion, which gives customers the next-higherbandwidth model for the same price. The Agilent InfiniiVision X-Series bandwidth upgrade option allows users to purchase the bandwidth performance they need today and upgrade it later. The X-Series integrates the capabilities of five instruments in one unit: an oscilloscope with an uncompromised waveform update rate of up to 1 million waveforms per second, digital channels (MSO), integrated WaveGen arbitrary waveform generator, integrated digital voltmeter and a serial protocol analyzer. All X-Series scopes come with a standard fast Fourier transform math function and are supported by the Agilent 64997A Spectrum Visualizer. InfiniiVision 3000 X-Series and 4000 X-Series scopes are supported by Agilent 89600B vector signal analyzer software to provide comprehensive RF domain measurements. ■ Agilent Technologies www.agilent.com Next-Generation System for Measuring Flicker Noise Agilent Technologies Inc. introduced the Agilent EEsof EDA E4727A Advanced Low- Frequency Noise Analyzer — a next-generation hardware and software system for measurement and analysis of flicker noise and random telegraph noise (RTN). Flicker noise has long been considered a critical characteristic of electronic devices. It significantly affects performance of circuits such as active mixers, voltage-controlled oscillators, frequency dividers, op amps and comparators, which are fundamental building blocks in RF, analog/ mixed signal, and high-speed wireline communication applications. Flicker noise and RTN are also both sensitive indicators of semiconductor material and manufacturing processes. With the semiconductor industry continuing to advance new technologies, the need for lower-frequency noise has never been greater. Agilent’s newest Advanced Low-Frequency Noise Analyzer is designed from the ground up to meet these new challenges. Its unique modular design allows it to minimize system noise, provide measurement capabilities at an ultra-low frequency, and offer the best high-voltage/ high-current handling capabilities on the market. ■ Agilent Technologies www.agilent.com 54 hf-praxis 6/2014

RF & Wireless Test & Measurement Tek‘s MDO3000 scopes are six-instruments-into-one Tektronix‘ MDO3000 series of oscilloscopes are not just scopes, as Tek refers to this range as six instruments in one, the six being scope, spectrum analyser, logic analyser, protocol analyser, arbitrary function generator and DVM. Instruments that are extensible – in terms of their feature set – and upgradeable, in parametric terms, are popular: as the manufacturers‘ documentation says, you are protecting your investment by not having to purchase a new unit when you move your own technology on. Defined in software As more and more of the features of T&M instrumentation has come to be defined in software, it has also become common that the instrument you buy is capable, and fullyequipped, to operate at a higher specification than the one you initially purchase. A software key, that you subsequently purchase, enables more advanced performance than you bought at the outset. This benefits the manufacturers, who can limit the number of variants that they build: and it means that your instrument is not obsoleted quickly, and does not have to return to its maker to receive an upgrade. It also enables the T&M vendor to offer you an “entry-point” specification – as distinct from an entry-point instrument – at a price that may fall into a lower capital-expenditure category. Tektronix has applied all of these marketing strategies to its new MDO3000 series of oscilloscopes – or, not just scopes, as Tek refers to this range as six instruments in one, the six being scope, spectrum analyser, logic analyser, protocol analyser, arbitrary function generator and DVM. The spectrum analyser function follows the pattern that Tek set with the MDO4000 series in that it is a separate full-function channel, and not an FFT-derived analysis function applied to the main oscilloscope inputs. The 3000 instrument “platform” can be upgraded in the field. Performance upgrades include analogue bandwidth of the oscilloscope and input frequency of the spectrum analyzer. Functional upgrades include the addition of digital channels, protocol analysis, arbitrary function generation or digital voltmeter measurements. Bandwidth upgrades, for both scope and spectrum analyser, are tied to the specific serial number of the instrument – although you enable the upgrade by software key, Tek will send you a new front-panel label in the mail. Certain other features – such as the protocol analyser, and specific protocols that you might purchase, are enabled by plug-in tokens that you can transfer between similar instruments. The DVM is not enabled at purchase, but you get that in return for registering the instrument. The MDO3000 Series oscilloscopes feature 2 or 4 analogue input channels with bandwidth ranging from 100 MHz to 1 GHz, 16 digital channels (optional) and one RF input channel matching the bandwidth of the oscilloscope (9 kHz up to analogue bandwidth). The RF input frequency on any model can be extended to 3 GHz. A “FastAcq” feature enables the MDO3000 oscilloscopes to run at more than 280,000 waveforms per second capture rate displayed on a digital phosphor display for easily finding infrequent anomalies in a signal. More than 125 available trigger combinations, automated serial and parallel bus analysis, innovative Wave Inspector controls, and optional automated power measurements round out the feature-set, and ensure comprehensive tools for every stage of debug. This functionality is extended with the addition of 9 optional serial protocol analysis packages – I2C, SPI, RS-232, USB 2.0, CAN, LIN, FlexRay, MIL-STD-1553, and Audio. The integrated, optional 50 MHz AFG functionality is more than twice as fast as competitive offerings, Tek says, with eight times the arbitrary waveform record length. While the integrated digital voltmeter (DVM) provides 4-digit AC RMS, DC, or AC+DC RMS voltage measurements, as well as 5-digit frequency measurements in a large, display that makes changes in your readings instantly visible. MDO3000 also get 3.9 pF passive voltage probing. For higher speed applications, 1 GHz (3 dB bandwidth) passive voltage probes are offered standard with 1 GHz instruments. When operating the instrument, the basic choice is analogue-scope or RF mode; otherwise, all enabled options can run at the same time. Differentiation between the 3000 series and the MDO4000 range – which also gets a restructuring of its pricing and feature set structure – is maintained by, among other aspects, the correlation between time-domain and RF measurements; the 4000 retains more capability in that respect. There are ten pre-configured model options, 2 or 4 channels at 100, 200, 350, and 500 MHz, and 1 GHz, bandwidth. All use the 2.5 Gsample/sec ADCs that Tek developed for existing scopes, that can be interleaved to 5 Gsamples/sec. ■ Tektronix www.tektronix.com hf-praxis 6/2014 55
