  • PicoScope 9211A Oscilloscope

PITTSFORD, N.Y, June 8, 2010 — Saelig Co. Inc. has introduced the PicoScope 9211A, an economical instrument specifically designed for time-domain reflectometry applications, providing a low-cost method of analyzing the real-world functionality of cables, connectors, circuit boards and integrated circuit packages.

It stimulates a device under test using two independently programmable 100-ps rise-time step generators and builds up an accurate performance picture from a sequence of reflected or transmitted pulses via its 12-GHz sampling inputs. The results can be usefully displayed as volts, ohms or reflection coefficient against time or distance.

As well as time-domain reflectometry and time-domain transmisson analysis, the instrument also can be used for mask-limit testing communications standards such as Ethernet, InfiniBand 2.5 G and 5.0 G, XAUI, ITU G.703, ANSI T1/102, RapidIO 1.25 G and 3.125 G, G.984.2, PCI Express 2.5 G and 3.0 G, and Serial ATA 1.5 G and 3.0 G. More than 150 industry-standard masks are included.

The oscilloscope features three trigger inputs: a DC to 1-GHz direct trigger, a 1- to 10-GHz prescaled trigger and a 12.3-Mb/s to 2.7-Gb/s clock-recovery trigger, as well as an internal 10-Gb/s software pattern sync trigger for averaging eye diagrams.

Unlike traditional, bulky benchtop instruments, it takes up very little bench space. The analyzer connects to a Windows PC via its USB 2.0 port, and an Ethernet port is also provided for remote operation over a network.

Available now, it includes all necessary calibrated cables, filters, power splitters and adapters.

A system in which a supplied signal causes the deflection of the electron beam in a cathode-ray tube, thus forming a visible trace on the phosphor screen of the tube and providing for examination of signal characteristics. A CRT oscilloscope is particularly convenient for studying repetitive phenomena, but a tube with a long-delay phosphor can be used to analyze a single electrical pulse. An oscilloscope equipped with a camera becomes an oscillograph.  
reflection coefficient
Parametric measurement for elliptical fiber and cable expressed as a ratio of the two-directional flow of power through the cable at any chosen point.
