Picosecond Pulse Labs Announces High-Resolution 9 ps Differential TDR Instrument.Business Editors/High-Tech Writers BOULDER, Colo.--(BUSINESS WIRE)--Sept. 25, 2003 Picosecond One trillionth of a second. Pronounced "pee-co-second." See space/time and ohnosecond. (unit) picosecond - 10^-12 seconds. Pulse Labs expands its Time Domain Reflectometry (TDR) instrument family with the introduction of the Model 4022 Differential TDR Source Enhancement Module. The Model 4022 provides 9-picosecond rise-time signals to measure features as small as 0.5 mm in differential communication links. It is designed to work in conjunction with either Agilent or Tektronix TDR products. When used with an Agilent or Tektronix TDR plug-in and a high-bandwidth (50 GHz or 70 GHz) sampling oscilloscope, the Model 4022 improves the resolution of TDR measurements by two to four times. It may also be used for TDR common mode measurements of a differential link. High-resolution TDR is particularly useful in the characterization of components, interconnects, backplanes, and circuit boards that are used in multi-gigabit differential communication (SERDES See serializer/deserializer. ) structures like XFI/XFP, LVDS (Low Voltage Differential Signaling) A transmission method for sending digital information. LVDS sends data over data high and data low lines rather than data and ground. , PCI Express, Serial ATA, Serial Attached SCSI See SAS. , Fibre Channel, HSBI HSBI High Speed Backplane Initiative and others. TDR measurements identify small physical transitions in connectors and component packages that impair performance. High-resolution TDR measurement results compare favorably with 65 GHz Vector Network Analyzer (VNA VNA abbr. Visiting Nurse Association ) measurements, but TDR techniques are faster, more intuitive, and do not require laborious system calibration. The Model 4022 can also be configured to deliver Time Domain Transmission (TDT) signals for both differential and common mode measurements. The Model 4020 Single Ended TDR/TDT Source Enhancement Module was announced earlier this year. The basic Model 4022 Differential TDR Source U.S. price is $23,995 with a six-week delivery interval.
