Parallel production testing for increased through-put
High quality, low cost alternative to bench top pattern generators and BERTs The Picosecond Advantage:
Instrument grade DC coupled output with the highest possible eye quality.Description:
The Programmable Pattern Amplifier (PPA) is an limiting amplifier module that is designed to produce instrument quality serial data streams and eye diagrams. The PPA contains an interface/controller board as well as a high-performance, custom hybrid output circuit. The module is oven calibrated for consistent performance across it's entire operating range (amplitude, offset, temperature, crossing point).
The PPA is available for purchase as single or multiple modules integrated into a LABware instrument (combines PPA modules, power supply, cooling, and USB interface). These LABware instruments (the Models 8010 and 8020B) come in several configurations.
The Model 8020B integrates connections for a differential input (pos. and neg.), two 1:4 splitters, and 8 PPA modules for independent programming of 4 differential outputs.
Currently, parallel serial test sources are very expensive. The Model 8020B's configuration allows it to be simply and easily connected to a single channel BERT or pattern generator instrument to produce multi-channel, programmable, high-speed serial data signals.
