The N2102B PXIT pattern generator is a 2-slot PXI module capable of generating a number of industry standard patterns, with very low jitter, from 622 Mb/s to 10.3125 Gb/s. The N2102B requires an external clock source for operation at these rates. The N2099A PXIT synthesizer is a 2-slot PXI module with dual RF outputs, tunable over a 2 GHz range. There are three options available that cover different frequency ranges depending on the required application. The N2099A is the ideal clock source for the N2102B. Both instruments form part of the Agilent PXIT family of modules. Other modules available include the N2100B PXIT DCA and the N2101B PXIT BERT which can also be used (via its at rate clock out) to drive the N2102B PXIT pattern generator.
