The HP 37717B is a multi-rate bit error measuring test set for comprehensive testing and verification of communication systems and networks. It generates and receives data patterns with G.821-compliant error analysis, supporting AMI, HDB3, and CMI coding schemes. The instrument delivers accurate error measurements in the presence of signal degradation, including half-rate cable loss up to 12 dB. This configuration includes options A1P, A3D, UH2, UH4, UKK, and US1, enabling advanced PDH/SDH and ATM testing across multiple rates and interfaces.
