Agilent 86108B Precision Waveform Analyzer

New architecture yields precision measurements and

easy-to-use operation

The 86108B combines two high-bandwidth channels, an instrumentation-

grade clock recovery which features variable loop bandwidth and peaking,

and a precision timebase into a single unit.

The ultimate in accuracy and ease-of-use for analyzing

high-speed electrical digital communications signals

Highest accuracy scope featuring:

• Ultra-low jitter < 50 fs (typ.)

• Wide bandwidth

> 35 GHz (Option LBW)

> 50 GHz (Option HBW)

• Clock-data delay mitigation (“O ns” delay)

Easy setup and operation:

• Simple one connection ‘triggerless’ operation

• Auto setup for serial bus differential signaling including PCI-

EXPRESS

, SATA, HDMI, DisplayPort, SFP+, 8 GFC, 10 GbE

PLL characterization/Jitter transfer:

• Flexible operation: Data or clock input/output,

50 Mb/s to 2 Gb/s or 25 MHz to 16 GHz

• Compliant: PCI SIG approved, SONET/SDH

Integrated hardware clock recovery:

- Continuous clock recovery rates:

• 50Mb/sto16Gb/s(Option216)

• 50Mb/sto32Gb/s(Option232)

- Adjustable loop bandwidth (LBW)/Type-2 transition frequency

(Peaking)

• “GoldenPLL”loopbandwidthadjustment

15 KHz to 20 MHz (rate dependent)

• Peaking0to>2dB(bandwidthdependent)

- Exceeds industry standards for SSC tracking

The Agilent 86108B precision waveform analyzer is a plug-in module

used with the 86100C/D DCA Wide-Bandwidth Oscilloscope. An optimum

combination ultra-low jitter, low noise, and wide bandwidth makes the

86108B the ideal choice in helping engineers develop and test designs for

PCI-EXPRESS

, SATA, SAS, HDMI, DisplayPort, SFP+, Fibre Channel, CEI,

Gb Ethernet, and any proprietary rate to 32 Gb/s. The 86108B overcomes

conventional test equipment limitations and provides designers with the

confidence that the waveform displayed by the oscilloscope is a faithful

representation of the true device performance for todays technologies as

well a future generations.

This combination results in the world’s most accurate scope measure-

ments available today. With setup similar to a real-time scope, it also

provides significant ease-of-use advantages over traditional sampling

scopes. The architecture virtually eliminates the trigger-sample delay in-

herent in most sampling instruments, and permits accurate and compliant

measurement of large amounts of periodic jitter (e.g. SSC) without the use

of specially matched cables which degrade performance.

PLL bandwidth, jitter transfer and jitter spectrum

The on-board phase detector of the 86108B allows for a precision mea-

surement of phase-locked loop (PLL) bandwidth, sometimes referred to as

jitter transfer. An external software application running on a PC controls

the jitter source to provide a modulated stimulus to the device under test

(DUT). The system is approved by the PCI SIG for PLL bandwidth compli-

ance testing. The fast and flexible measurement can also test SONET/SDH

and other PLL designs.
