High-bandwidth oscilloscopes

16 May 2012 Test & Measurement

Agilent Technologies has rolled out new Infiniium 90000 Q-Series oscilloscopes with real-time bandwidth of 63 GHz on two channels and 33 GHz on four channels. The new lineup includes 10 four-channel models ranging from 20 GHz to 63 GHz, all of which are bandwidth upgradeable.

At its maximum bandwidth the Q-Series breaks the 60 GHz barrier, with a -3 dB point of 63 GHz. The 33 GHz model allows engineers to simultaneously trigger on and capture signals on all four channels with no compromise. These two specifications allow the oscilloscopes to make measurements on devices designed to conform to emerging standards.

Key capabilities include:

* Direct digitisation of M-band signals (60 GHz to 100 GHz).

* Capture of the third harmonic on 28, 32 and 40 Gbps digital signals.

* Analysis of IEEE 802.3ba 40/100/400-GbE and Optical Internetworking Forum CEI 3.0 signals.

* Measurement of up to four differential channels in a single acquisition for unravelling difficult cross-talk problems.

* Direct measurement of voltage swings larger than 1 V when high-bandwidth and general-purpose measurements need to be made with the same instrument.

The 90000 Q-Series improves upon Agilent’s use of custom integrated circuits and multichip module packaging with an exclusive new technology called RealEdge. RealEdge comprises a combination of new architectures, next-generation microcircuits and thin-film components, and advanced application of Agilent’s indium phosphide semiconductor process. This new technology enables high-frequency capability while maintaining what Agilent claims are the industry’s lowest noise and jitter measurement floor (75 fs).
