The ESOR 2904 is a high performance, flexible and cost effective four channel Pulse Pattern Generator (PPG) and Error Detector (ED) that can operate from 24.6 to 29.5 Gb/s along with half rates. It is capable of generating a Pseudo Random Bit Sequence (PRBS) or a user defined 40 bit fixed pattern to test signal integrity of digital communication system links. PRBS patterns of 2^7, 9, 15, 23, 31 are supported. It is a standalone Bit Error Rate (BER) test solution that incorporates an internal full rate clock synthesizer therefore avoiding the expense of an external precision clock source. Optional features: Tilt bar, custom power up configuration for standalone operation, parallel I/O control, dipswitch control, LED status diagnostics, individual PPG or ED configurations, face plate for 19 inch rack attachment, loopback cables or adding attenuators to the ED to adjust sensitivity.
