What does a pattern generator usually do?
Data Pattern Generators offer a complete and unique portfolio of instruments to address a wide range of applications starting from Digital Logic and Semiconductors characterization, Aerospace & Defense compliance testing, Mixed Signal Systems testing to Signal Integrity experiments. Active Technologies offers two different product families: Digital Pattern Generator (DPG) and Serial Data Pattern Generator (SPG).
Which pattern is produced by generator?
The DPG generator allows you to create digital stimuli synchronous with analog channels to test and debug Mixed-Signal applications: they can be used for FPGA / peripheral / ASIC emulation and stimulation, protocol level testing setup/hold verification, production test, mixed signal testing and general digital stimulus. The Serial Data Pattern Generator family is designed to generate a stream of binary information. The binary data stream is generated through the front panel BNC/SMA connectors.
With up to 8 channels of data stream, built-in PRBS sequences, modulation features, transition shaping and the flexibility of a powerful analog front end, the SPG is the perfect tool to address the most challenging application where the digital data should be modelled with analog characteristics.
How do you use a pattern generator?
The DPG generates digital stimuli for the Device Under Test using a digital connector and a digital probe (LVDS or LVDS to LVTTL). The SPG generates the data stream through the front end BNC or SMA connectors.
