Keysight (Agilent) 3781B Pattern Generator

The HP 3781B Pattern Generator used with a HP 3782B Error Detector forms a flexible, high-performance error measuring system for use in the North American digital hierarchy. Standard interfaces include DS I, DS I C, DS2, and DS3. Binary ECL operation to 50 Mb/ s covers general-purpose requirements. Automated or remote measurement capability with HP-IB. Measurements can be made on all types of digital transmission systems including cable, digital radio, satellite, and lightwave. The pattern generator provides a wide range of test patterns including PRBS for simulating live traffic and shorter WORD patterns for checking pattern sensitivity in transmission equipment. Binary and code error injection capability is included for stress-testing line terminating equipment. A jitter modulation input is provided to add controlled amounts of jitter to the output test pattern and perform jitter tolerance tests on equipment interfaces.

Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Data Rate
Data Rate is the maximum number of bits of information which can be transmitted per second, as in a data transmission link. Typically expressed as megabits per second (Mbps).

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

SONET
Synchronous Optical NETwork (SONET) is a fiber-optic transmission system for high-speed digital traffic. Employed by telephone companies and common carriers, speeds range from 51 Mbps to 40 Gbps. SONET is an intelligent system that provides advanced network management and a standard optical interface. Specified in the Broadband ISDN (B-ISDN) standard, SONET backbones are widely used to aggregate T1 and T3 lines. The European counterpart to SONET is the Synchronous Digital Hierarchy, and the term "SONET/SDH" is widely used when referring to SONET
