Tektronix CSA 907R 1 MHz to 700 MHz Error Detector

The Tektronix CSA 907R is a high-performance error detector for characterizing and validating high-speed digital communication systems across 150 kHz to 700 MHz. This receiver module identifies, analyzes, and quantifies errors in digital data streams with precision measurement capabilities essential for LAN, WAN, Ethernet, FDDI, SONET/SDH, ATM, and satellite system testing. When paired with the CSA 907T pattern generator, the CSA 907R forms the complete CSA 907A BERT system for end-to-end signal validation.
