SANTA CLARA, CA--It's not easy doing leading-edge optical and electronic-communication
system design: You need instrumentation that's better than the
leading-edge performance you're trying to achieve. The 86108B precision
waveform analyzer module from Agilent Technologies for the company's
86100C/D DCA wide-bandwidth oscilloscope family targets engineers
testing high-speed links such as IEEE 802.3ba (40/100 GB Ethernet);
optical Internetworking Forum CEI 3.0, Fibre Channel INCITS T-11 32G,
and others.
Its integrated precision timebase and clock-recover design yields
typical residual jitter below 50 femtoseconds (rms) for the
high-bandwidth option, while providing continuous data-rate coverage
form 50 Mbps to 32 Gbps (along with peaking control and adjustable loop
bandwidths to 20 MHz for enhanced PLL response).
The internal triggering architecture allows simple connection schemes (relatively speaking, of course), along with analysis of low-amplitude signals and elimination of clock-data delay that can corrupt jitter measurements. An internal phase detector supports accurate measurements of PLL bandwidth, jitter transfer, and jitter/phase noise spectrum.

The low-bandwidth option offers two channels with 35 GHz bandwidth, residual jitter below 60 fs/90 fs noise of 500 μV/700 μV (typical/guaranteed, respectively), internal clock recovery rates of 50 Mbps to 16 Gbps or 50 Mbps to 32 Gbps, depending on option. The high-bandwidth option instrument's bandwidth is 50 GHz, with jitter specifications of 50 fs/70 fs, noise of 800 μV/980 μV, (typical/guaranteed, respectively) and the same clock recovery rates as the low-bandwidth option.

Price and availability: Of course, such performance doesn't come easy, nor cheap, but the challenges it solves are neither, as well. Prices start at $80,000 for the unit, which is available now.
