HP 71612B 12 Gb/s Error Performance Analyzer

The HP 71612B Error Performance Analyzer addresses applications for high speed digital testing up to 12 Gb/s, including R&D and manufacturing test of lightwave components and sub-assemblies, advanced computer technology and high-capacity communication systems.

The analyzer operates from 1 to 12 Gb/s and will operate down to 100 Mb/s with a clock-source extension. Features include high quality waveforms, versatile triggering, and sufficient memory for running multiple SONET and SDH frames at STS-192/STM-64. Use error location analysis to help identify the cause of pattern-dependent errors.

Powerful application software to speed measurement time.

The HP E4543A Q Factor and Eye Contour application software is designed to simplify the characterization of high speed optical communication links, automatically calculating the Q figure of merit.

Adaptable application software for full functional testing.

The HP E4544A OC-192/STM-64 application software automatically constructs SONET/SDH frames for functional test of network elements. Features including error and alarm generation plus CID stressing patterns.

Except where otherwise stated, the following parameters are 
warranted performance specifications. Parameters described as 
"typical" or "nominal" are supplemental characteristics that provide 
a useful indication of typical, but non-warranted, performance 
characteristics. All specifications are for 0° to 40°C after 30 
minutes warm-up.

In the pattern generator,any pattern may be split into two equal-length

patterns may be loaded from, or saved to, a 3½ inch, MS-DOS® 

format floppy disk.

alternate-pattern switch and data output on/off switch. There are 

outputs for clock and inverted clock, data and inverted data and

where n = 3 to 9.
External: TTL levels (active low).



Error Detector
The error detector has clock and data inputs and an input which inhibits 

error counting. There are outputs for errors and pattern trigger. 

The error detector has both manual and automatic setting of decision 

threshold and clock/data phase alignment.
