  • Page 17: Section 1 General

    GENERAL 1.1 Features The MP1763C Pulse Pattern Generator has two data output channels (DATA and DATA) and three clock output channels (CLOCK1, CLOCK1, CLOCK2). The MP1763C is used with the MP1764A/C Error Detector to test high-speed digital communication systems and high-speed semiconductors. It operates over the 50 MHz to 12.5 GHz frequency range and generates four pulse patterns: alternate, programmable, zero substitution, and pseudorandom.
