12-GHz Sampling Scope Handles TDR/TDT Analysis

Designed for time-domain reflectometry (TDR) and time-domain transmissometry (TDT) analysis, the PicoScope 9211A sampling oscilloscope stimulates a device under test using two independently programmable 100-ps, rise-time step generators and builds up a performance picture from a sequence of reflected or transmitted pulses via its 12-GHz sampling inputs. The results can be displayed as Volts, Ohms, or reflection coefficient against time or distance. The instrument can also be used for mask-limit testing communications standards such as Ethernet, InfiniBand 2.5G and 5.0G, XAUI, ITU G.703, ANSI T1/102, RapidIO 1.25G and 3.125G, G.984.2, PCI Express 2.5G and 3.0G, and Serial ATA 1.5G and 3.0G. Over 150 industry-standard masks are included. Other features include three trigger inputs, a dc to 1-GHz direct trigger, 1- to 10-GHz pre-scaled trigger, and a 12.3 Mb/s to 2.7 Gb/s clock- recovery trigger. Additionally, the analyzer connects to a Windows PC via its USB 2.0 port and an Ethernet port on tap for remote operation over a network. Price for the PicoScope 9211A is $10,999.
