TTC T-BERD 310-1 DS1/DSO Analyzer

The TTC T-BERD 310-1 DS1/DSO Analyzer is a modular digital communications test instrument engineered for DS1 and DSO signal generation, measurement, and analysis across telecommunications infrastructure. It addresses testing requirements in central offices, laboratories, mobile telephone switching offices, and manufacturing environments with field-upgradeable architecture supporting evolving network demands.

Technical Specifications

The 310-1 configuration delivers DS1/DSO analysis with DS1 scanning and automatic payload detection. It measures transmit and receive frequency, signal level, and power across digital circuits. Pulse shape analysis conforms to 1991 and 1993 ANSI and ITU-T specifications for DS3 circuits, enabling correlation of error bursts with level dropouts and frequency variations during installation. Jitter measurements extend to DS3 and SONET signals, including in-service DS3 jitter detection for SONET SPE pointer adjustment analysis. Frequency spectrum analysis operates on demodulated jitter output.
