Cover Story Keysight

Cover Story Keysight Technologies Introduces 65-GSa/s High-Speed Arbitrary Waveform Generator Keysight Technologies, Inc. added a 65-GSa/s, 20-GHz modular instrument to its portfolio of arbitrary waveform generators. The new high-speed, wide-bandwidth M8195A arbitrary waveform generator allows engineers to generate digital, multilevel (e.g. PAM4, MIPI C-PHY) signal scenarios and test their electrical and optical links with complex modulated signals up to 32 GBaud and beyond. This makes the M8195A the most versatile signal generator in the industry. The instantaneous bandwidth from DC to 20 GHz allows researchers to create extremely short, yet precise pulses. Developers of radar, electronic warfare, satellite and wireless applications can use the M8195A AWG to create wideband signals up to 20 GHz. The instrument delivers high sample rate and wide bandwidth in combination with industry-leading port density. This unique functionality allows engineers to make reliable, repeatable measurements when they are working on binary and multilevel, multichannel digital interfaces as well as coherent optical and wideband communication applications. The M8195A uses out-of-the box and in-situ calibration and signal predistortion methods to generate exceptionally clean signals – even at the highest data rates. Engineers also can use these techniques to embed or de-embed the channel between the generator and the device under test. The implementation in hardware allows change of parameters at runtime. Highly realistic signal scenarios With up to 16 GSamples of waveform memory, the M8195A allows designers to create long and highly realistic signal scenarios. Multiple M8195A modules can be combined in a system with up to 16 fully synchronous PAM4 signal at 28 GBaud ( = 56 GBit/s) PAM4 signal with distortion 44 hf-praxis 2/2015

RF & Wireless Frequency Response 16 QAM at 32 GBaud channels in a single 5-slot AXIe chassis. “The M8195A uses proprietary ASIC technology to deliver a combination of the fastest speed, widest bandwidth and highest port density,” said Juergen Beck, vice president and general manager of Keysight’s digital and photonic test business. “This enables customers to economically test their multichannel, high-speed designs to the limit of required functionality.” The M8195A arbitrary waveform generator helps engineers to: • Generate four channels of multilevel signals (e.g PAM4) with programmable distortions and jitter up to 32 Gbaud. • Generate two pairs of complex modulated baseband signals (four channels) for coherent optical applications up to 32 GBaud and beyond. • A maximum sample rate of 65-GSa/s with 20 GHz of analog bandwidth on up to four precisely aligned channels per 1-slot AXIe module simultaneously. • Up to 2 Vpp differential output voltage and adjustable DC offset in a -1 to 3.3 V window. • The ability to build realistic scenarios with up to 16 GSa of waveform memory. The M8195A runs on an AXIe modular system designed for high-performance instrumentation and can be used with a 2-slot or 5-slot chassis. ■ Keysight www.keysight.com Skyworks Zirkulatoren und Isolatoren IL < 0,12dB, -40°C bis +95°C, 2110 – 2170 MHz 1800 – 2700 MHz, 23 dB Isolation, 8,5 mm Ø IMD < -90 dBc (2 x 50 W), 925 – 960 MHz Peak Power bis 2kW für S-Band Radar und IFF Integration in kundenspezifische Gehäuse Trans-Tech keramische Filter Subminiatur-Filter 1,55 mm hoch, 350 MHz bis 6 GHz kundenspezifische Filter mit optimierter Keramik koaxiale Filtermodule als Tief-, Hoch-, Bandpass keramische Filter bis 100 W CW für LTE koaxiale Resonatoren und Induktivitäten Trans-Tech temperaturstabile dielektrische Resonatoren Trans-Tech dielektrische und magnetische Materialien MRC GIGACOMP GmbH & Co.
